Acadia National Park Natural Resource Report 2006-02. ABSTRACT

This report outlines the goals, objectives, and methods of the Acadia National Park lake monitoring program, and summarizes the data collected in the 2002 through 2005 seasons. Field measurements and water samples were taken monthly at ten park lakes from May through October each year, providing data for a variety of water quality parameters that can serve as indicators for the effects of atmospheric deposition, cultural eutrophication, and climate change.

The monitoring data indicates that the lakes recovered from the effects of the 2001 drought in 2002. Secchi transparency and lake water levels followed the precipitation trends of the seasons. Dissolved oxygen, pH, acid neutralizing capacity, and nutrients all generally appeared to be relatively stable with concentrations generally within the historical range of variability for these lakes.

Although no statistical analyses were performed in this report to determine long-term data trends, a primary recommendation is that such an analysis be conducted to enhance the understanding of the current condition of the park's aquatic resources.

INTRODUCTION

Freshwater resources at Acadia National Park (ANP) include 24 named lakes (Figure 1), 34 named streams, and numerous wetlands within or adjacent to the park boundary. The current lake monitoring program has largely evolved from recommendations of a 1997 workshop designed to develop long-term monitoring strategies for ANP freshwater resources, and guidance outlined in the Acadia National Park Water Resources Management Plan (WRMP) (Kahl et al., 2000). Specific monitoring protocols have been selected to provide the information needed to detect changes in aquatic ecosystem structure and function caused by natural processes and human-induced factors. Lake monitoring forms the ‘core’ of the long-term freshwater monitoring program at ANP, and is a cooperative effort involving park staff, the US Geological Survey (USGS), University of Maine, Maine Department of Environmental Protection (MDEP), volunteers and others.

A representative subset of all park lakes, sampled monthly from May through October, makes up the foundation of the monitoring program. These 10 lakes range in size from 1 acre to 897 acres, with maximum depths from less than 3 meters to more than 45 meters (Table 1). All water monitoring data are incorporated into a comprehensive ANP database that includes recent as well as historical water quality data for park waters.

The major water related concerns that could affect ANP resources include atmospheric deposition, toxic contaminants within the watershed, input of nitrogen and other nutrients, and climate change. In addition to the lake monitoring program, park staff monitor benthic stream macroinvertebrates and bacteria at ANP swim beaches. There are also a number of water related research studies currently being conducted at the park that will help to better define water quality and watershed processes and function at ANP.

MONITORING OBJECTIVES

The primary objective of the ANP lake monitoring program is to detect changes in aquatic ecosystem structure and function; and determine if, and to what degree, human-induced factors are contributing to these changes. In order to measure human-induced changes it is necessary to determine the normal variability inherent in natural aquatic systems, and to establish baseline conditions from which future changes can be detected.

Specific objectives of the lake monitoring program are:

1) characterize existing water quality conditions and establish a baseline for future comparisons;

2) to serve as an early warning system for anthropogenic effects such as non-point source pollution (cultural eutrophication), climate change, and atmospheric deposition of acidic and toxic contaminants, nitrogen, and other nutrients;

3) assist in identifying potential sources of pollution;

4) provide water quality data and information needed to manage and protect other ANP resources;

5) track long and short-term trends.

As described previously, the process of designing a long-term monitoring program for freshwater resources was initiated at a workshop held in January of 1997 at ANP. Participants with diverse and multidisciplinary backgrounds represented a variety of state, federal agencies and academia at the workshop. The workshop concluded that the primary threats to ANP water resources are impacts associated with atmospheric deposition and nutrient enrichment (cultural eutrophication). Expanding and enhancing the existing ANP lake monitoring program was recommended as being a strategy to provide a broad foundation upon which additional water related monitoring and research can be supported.

METHODS

An Interim Report was prepared describing the 1997 workshop accomplishments, suggested monitoring priorities, and research and inventory needs (Kahl and Manski, 1997). Current monitoring protocols have been adopted based on recommendations in the Interim Report and guidelines identified in the WRMP. There has been no evaluation of monitoring protocols and their effectiveness in addressing set objectives since the program’s inception in 1997.

Because of funding and staff limitations, annual comprehensive monitoring of all ANP lakes, streams and other surface waters is not realistic. However, lakes to a large extent reflect the hydrogeochemical processes that occur within their respective watersheds. Therefore, the current freshwater monitoring program focuses on a subset of park lakes that provide a range of geophysical and ecological conditions, and allows for a preliminary assessment of changes and impacts associated with human related activity.

Sampling locations

The core monitoring design identifies three subsets of lakes to sample (Table 1.). The first, is a set of five lakes (Jordan Pond, Bubble Pond, Sargent Mountain Pond, The Bowl, and Witch Hole Pond) that are sampled to determine response to acidification and changes in atmospheric deposition. These lakes were selected to be representative of: a) the main large/deep water lakes on Mount Desert Island that are most associated with ANP (Jordan and Bubble ponds); b) smaller headwater and/or high elevation lakes most likely to show chronic acidification trends (Sargent, The Bowl); and c) an organically affected lake, as it is adjacent to wetlands (Witch Hole).

The second subset includes five lakes sampled for indicators of nutrient enrichment (Witch Hole Pond, Upper Hadlock, Seal Cove, Echo Lake, and Jordan Pond). These lakes were selected to be representative of the broad range of ANP lakes vulnerable to cultural eutrophication primarily from surrounding residential development. These lakes were also selected based on a variety of physical and environmental factors (e.g. size/depth, morphology, trophic state, watershed/ ecosystem type, amount of watershed development, burned/unburned in a major fire in 1947, amount/type of recreational and other human use). Jordan Pond was included on both lists because it is considered the "jewel of Acadia waters” and perhaps the entire state.

A third group of lakes that are sampled as part of the core lake monitoring program are lakes with existing long-term monitoring records (Secchi transparency, some chemical/physical parameters) and are not included in the first two lake sets. These lakes, Eagle Lake, Long Pond (MDI) and Bubble Pond (also included in the set of acidification lakes) are sampled a minimum of once monthly May through October for temperature and Secchi, pH, ANC, and dissolved oxygen/temperature profile.

Sample collection and analysis

The analytes selected for the acidification and eutrophication sampling regimes (Table 2.), and the annual monitoring schedule (Table 3.), are essentially unchanged since 1997 and follow closely the recommendations of the workshop. Acidification parameters are analyzed at the University of Maine (UMO) lab on samples taken in April and October during spring and fall turnover. Eutrophication parameters are analyzed at the UMO lab on samples taken in June and August, to represent the spectrum of productivity developing through summer season. Two additional measurements have been added to the eutrophication sampling regime: water column light extinction/attenuation using a LI-COR radiation sensor (scaled back to 1 profile/lake during the 2005 season), and weekly lake surface level (stage) monitoring during the open water season spring through fall.

The lake sampling regime entails collecting half-meter deep grab samples from the deep hole (or center, in the case of lakes with uniform depth) of the lake for acidification chemistry, based on the assumption that early spring and late fall water columns are relatively homogeneous. For eutrophication chemistry, an epilimnion core sample (4-10 meter depth) is collected at the deep hole if the lake is stratified, or a half-meter grab sample if unstratified. For lakes with poor accessibility by boat, a throw bottle was used in fall 2003 and spring/fall 2004 and 2005 to collect epilimnion grab samples. The throw bottle took samples at a depth of 0.6 meters, at a distance of about 9 meters from shore.

Specific methods used for field measurements, sample collection techniques, and QA/QC procedures are described in the Acadia National Park Lake Monitoring Field and Laboratory Methods (Gawley, 1996). Secchi disk transparency, weather conditions; dissolved oxygen (DO), temperature, and light penetration profiles, and lake stage were measured in the field. A YSI 52 meter was used to measure DO and temperature, and LI-COR spherical PAR and deck cells measured light penetration. Light attenuation coefficients were calculated using methods developed for the NPS North Atlantic Coastal Parks (Kopp and Neckles, 2004). Lake stage was measured from a drilled hole ("tape down point") in a large rock in each pond using a wooden leveling stick and folding ruler.

Laboratory analysis for acidification and eutrophication parameters was conducted by the Environmental Chemistry Lab at the University of Maine in from 1996 to 2003. Beginning in 2004, samples were analyzed at the George Mitchell Center for Environmental and Watershed Research Laboratory at the University of Maine. Chemical analysis (summarized in Table 4) and QA/QC procedures followed by the two EPA-certified University of Maine labs were similar in methods and protocol. Independent audits performed by Environment Canada in 2004 between the two UMO labs indicated data were consistent and not compromised for long-term analysis. The GMC continues to participate in both EPA and Environment Canada audits to ensure data quality.

A recommendation of the 1997 workshop was for ANP staff to also perform analysis on closed cell pH, conductivity, ANC, and color at the park laboratory. Procedures for ANP chemistry and QC criteria are described in Gawley (1996) and Seger (2005). The workshop additionally recommended conducting an interlab comparison between the park lab and the University of Maine lab for these analytes. This comparison would provide an opportunity for park staff to evaluate the in-house capability to perform these standardized analyses.

For data up to 2001, casual comparisons suggested there was good agreement in most instances between the UMO and ANP labs, though a comprehensive statistical evaluation was not done. Monthly chemical analysis of these four analytes has continued at the ANP lab to maintain the dataset. In a more in-depth report (Seger, 2005), preliminary interlab comparisons were again performed on 2002 to 2004 data using percent difference calculations. For consistency, and because agreement between the ANP lab and the EPA-certified UMO lab was not always within acceptable range, only UMO data are used for graphical analysis of chemical parameters in this report. Graphs and descriptive statistics were produced with Microsoft Excel 2003 software.

RESULTS AND DISCUSSION

General

Data from the ANP and UMO labs from 2002 to 2005 are included in tabular form in Appendix A. The lakes sampled in the ANP monitoring program have been selected to be representative of the broad range of hydrogeochemical and morphological conditions at the park. The core monitoring lakes range in size from 1 to 897 acres in surface area, and from 3 meters to 45 meters in depth. Although park lakes are poorly buffered, most are circumneutral in pH with trophic levels ranging from oligotrophic to eutrophic (most are mesotrophic), and acid neutralizing capacity (ANC) among the lowest in Maine. In general, the data indicate concentrations for most water quality parameters were within their historical range and continued to meet park water quality objectives.

Precipitation Trends

Statewide, 2001 to 2002 was the worst drought period in over thirty years (Lombard, 2003) and this is reflected in precipitation patterns at Acadia National Park as well. By late spring 2002 surface water levels returned to normal due to increased precipitation; however, groundwater levels statewide remained low throughout 2002 as there is a lag in response to climatic shifts in groundwater levels (Stewart et. al, 2003). Mean precipitation measured at the McFarland Hill National Atmospheric Deposition Program (NADP) site at Acadia National Park headquarters for the period 1982-2005 was 54.51 inches. Annual precipitation trends for this period are shown in Figure 1. For the Acadia area, 2002 to 2004 annual precipitation consecutively decreased over the three years from above normal conditions to a drier period (though 2004 was not nearly as dry as 2001). In 2005 annual precipitation reached the highest level since the NADP began monitoring at Acadia National Park (Figure 2).

Precipitation is one factor that has had relatively large seasonal fluctuations over the years. For example, above normal annual precipitation and temperature conditions occurred in 2002, near normal in 2003, then below normal in 2004 (though temperatures were average), then increasing again in 2005. Seasonal changes however were different between the years. Winter temperatures, snow levels, spring rainfall, and annual precipitation were less in 2004 than the previous two years, but 2004 had a wetter/cooler summer and a drier fall than 2002 and 2003 (Figure 3). In 2005 precipitation was the highest it had been in over 24 years, but most accumulation occurred in winter, spring, and fall. The 2005 summer was similar in mean rainfall and temperatures to 2002 and 2003. Mean summer (June-August) precipitation volumes were 3.15, 3.69, 4.60, and 2.12 inches in 2002 to 2005 respectively. Again though, 2004 annual rainfall was below normal. Both seasonal and annual shifts in precipitation and temperatures can have distinctive short-term and cumulative effects on lake levels, physical lake properties, and water chemistry.

Lake Stage Monitoring

Spring lake levels are influenced by snowmelt and spring rains. Summer and fall levels are influenced by precipitation and evapoconcentration. Additional factors that can affect lake levels are drinking water demand in water district lakes (Bubble, Eagle, Upper Hadlock, Jordan), use for fire control (the Tarn), and human and beaver damming activity. Some lakes are flashier in response to the timing, frequency, and duration of rainfall depending on their watershed influences and flushing rate. In general, lake levels reflected rainfall trends throughout the summer and into fall during 2002 to 2005 (Appendix B). Upper Hadlock, The Tarn, and sometimes Bubble appeared to be more responsive to precipitation.

Emergent vegetation at the Tarn and Aunt Betty ponds has continued to increase in recent years. Both of these ponds are naturally very shallow with summer water levels between 1 and 2 meters, as well as have active beaver activity. These ponds appear to be slowly succeeding to freshwater wetlands as organic sediments accumulate on the pond bottom.

Secchi Disk Transparency

One long-term water quality measurement available for the core monitoring lakes at ANP is Secchi depth transparency. Mean, maximum, and minimum annual transparency and values for the core ponds (except Sargent Mountain Pond and The Bowl), can be seen in Table 5. Raw data of monthly readings are available on the University of Maine's Pearl website (http://pearl.maine.edu/).

Mean annual transparency has remained remarkably stable in the core ponds despite a number of different monitors over the years. Some ponds appear to have experienced a slight increase in transparency since the mid-1990’s, however this probably corresponds to a change in monitoring equipment. In 1995, the Secchi viewing scope was modified by adding two side flaps that shade the observer’s eyes from peripheral light. These flaps help to reduce the glare seen by the observer looking through the scope and tend to increase the transparency reading.

Graphs of annual mean Secchi transparency and Trophic State Index (TSI) data from 1980s to present are included in Appendix C. The more oligotrophic lakes appear to have slightly more variation in annual Secchi readings and thus transparency conditions in these lakes may be more responsive to precipitation and other environmental influences. The general Secchi trend in most of the core lakes was a decrease in transparency since the drought of 2001. This follows the pattern of increased summer precipitation from 2002 to 2004. Often during drier conditions lakes will become more clear due to less runoff of nutrient and soil inputs. In 2005 several lakes continued to have decreased secchi readings, due most likely to extremely high levels of spring and fall precipitation, and cumulative effects of a high rainfall year.

Table 5. Secchi Disk Readings

Dissolved Oxygen

Dissolved oxygen (DO) is the measure of the amount of oxygen occurring throughout the water column. Low oxygen rates can stress or directly kill organisms. Water with less than 1 mg/L of oxygen is considered anoxic and can promote the release of phosphorous from sediments and possibly increase algal blooms; less than 5 mg/L (hypoxia) is generally considered stressful to most coldwater fish. Temperature affects DO as well, in that increased water temperature leads to decreased oxygen solubility. Near the bottom of the water column, the more mesotrophic Seal Cove, Witch Hole, and Upper Hadlock ponds often reached below 5 mg/L or became anoxic during the months July through September. The more oligotrophic lakes sometimes reached below 1 mg/L, but only directly above the bottom sediment.

Graphs of mean hypolimnion depth, dissolved oxygen, and temperature (Appendix D) suggest that these parameters are staying relatively constant over time. Although annual mean hypolimnion temperatures are somewhat variable due to normal fluctuations in climate, both mean hypolimnion depths and DO levels appear to be either stable or slightly increasing. This indicates that the majority of the water column in park lakes continues to be well oxygenated, since most hypoxia occurs in the hypolimnion and the relative proportion of hypolimnetic water remains fairly unchanged.

Eutrophication Subset of Lakes

In the lakes sampled for eutrophication indicators, annual and seasonal (June/August) values for total phosphorus, total nitrogen and chlorophyll a from 1996 to 2005 continued to be

14

relatively stable with concentrations generally within the historical range of variability for these lakes (see Appendix E.). Although tests for statistically significant trends were not conducted, general patterns were observed, with some anomalies. Often total phosphorous (TP) and total nitrogen (TN) were higher in the early summer compared to late. This is most likely due to spring runoff from snowmelt and rainfall. Chlorophyll a was higher in the late summer, as this is the prime growing time for phytoplankton and algae. TP concentrations from 1996 to 2005 in Witch Hole Pond were the highest of the five lakes, with a mean concentration of 9.9 ug/L. Mean total phosphorus concentration in the other eutrophication lakes ranged from 2.8 ug/L in Jordan Pond to 6.1 ug/L in Seal Cove Pond. Upper Hadlock had an unexplainably high TP concentration of 12 ug/L in June 2001, but dropped to 3.9 ug/L in August, and then went back up to 11 ug/L the following June 2002. Most likely this is due to spring rain runoff. In early summer 2003, both TP and TN in Jordan were unusually high at 10.3 ug/L and 0.328 mg/L respectively. TN continued to be high in the late summer. In 2004 the levels were back to normal. TN ranged from a mean low of 0.134 mg/L in Bubble Pond to 0.377 mg/L in Witch Hole Pond from 1996 to 2005. Mean chlorophyll a concentrations ranged from a low of 1.0 ug/L in Jordan Pond to 4.2 ug/L in Witch Hole Pond from 1996 to 2005.

Light Penetration Profiles

Light penetration profiles were collected monthly for many of the eutrophication lakes from 2002 through 2004, using a LI-COR submersible PAR cell and surface deck cell. The goal of this sampling was to obtain baseline data and to attempt to determine a relationship between Secchi transparency and the light meter readings. The light penetration data and corresponding Secchi depths were examined by USGS staff in 2005 during the development of sampling protocols for NPS Vital Signs monitoring. Although the direct correlation between the Secchi depth and meter values was not as strong as anticipated, attenuation coefficients calculated from the profile data were shown to be a remarkably consistent index for seasonal comparison of lake transparency (Lombard, 2005; pers.comm.).

The profile information from deeper lakes may also be of value to compare with dissolved oxygen and temperature data, and to relate to productivity/food web studies. Secchi depth has long been considered a suitable and easily obtainable index for transparency, and the USGS comparison studies did not suggest there would be any advantage to augmenting (or replacing) Secchi transparency with LI-COR profiles in lakes that are deep enough to obtain Secchi readings. However, the greatest value of the LI-COR profiles is the ability to have an index of comparison (the attenuation coefficient) in shallower lakes. This data gap was noted in the 1998-2001 Lake Monitoring Report (Breen, et.al, 2002), so the sampling strategy was modified in 2005 to collect light profiles only in lakes too shallow for Secchi disk readings. Although each shallow lake was profiled once in 2005, increasing sampling frequency in future years would provide a more statistically robust sample size.

lake from 1996 to 2005 (see Appendix G). From 1998 to 2005 Sargent Mountain Pond was the most acidic lake with a mean air equilibrated pH of 4.91, and mean ANC of –11.35 ueq/L. Jordan and Bubble Ponds were the most circumneutral lakes with mean pH values of 6.9, and mean ANC of 58.32 ueq/L and 56.10 ueq/L respectively. Spring pH and ANC tended to be somewhat lower than fall values in the Bowl, Jordan, Bubble, and Witch Hole Ponds, most likely due to spring melt episodic acidification. The reverse pattern was true for Sargent Mountain Pond, which is different in that it is a higher elevation headwater lake. However, in 2005 more often fall pH and ANC values were lower in the lakes than in spring. This is most likely due to above average fall precipitation (12.9 inches in the ten days preceding the fall sampling dates).

Interlab Comparison

Detailed results and discussion of the interlab comparison can be found in Seger, 2005. Overall results showed that apparent color analyzed at ANP is often less than true color values from the UMO lab. However, ANP values have been consistent since analysis began at ANP and are generally consistent within acceptable QC limits. ANC had the greatest discrepancy between the two labs. Conductivity differences between the two labs were generally less than 10%. Closed cell pH had the best agreement between the two labs. Again, these results were from a preliminary comparison. Percent difference limits followed were those used by the UMO lab for acceptable differences between field duplicate samples. Because differences are inevitable due to slightly varied analytical methods between the two labs, these percent difference limits may have been too strict. A stronger statistical comparison using peer-reviewed standards will be completed in the near future.

CONCLUSIONS

In summary of the results reported here using 2002 to 2005 data (and 1996 to 2005 data for graphs presenting longer periods of record), recovery from the 2001 drought occurred in 2002, with the two subsequent years becoming consecutively drier on an annual basis, although summers received relatively average amounts of precipitation. 2005 was an anomalous year with very high precipitation levels (totaling 84.3 inches), yet an average summer in temperature and rainfall. Secchi transparency and lake levels followed the precipitation trends of the seasons. Dissolved oxygen levels were within the expected ranges for the trophic type of each lake. In the eutrophication sampling subset of lakes, annual and seasonal (June/August) variation for total phosphorus, total nitrogen and chlorophyll a from 1996 to 2005 continued to be relatively stable with concentrations generally within the historical range of variability for these lakes. A notable exception is that TN appeared to be increasing over the years in Seal Cove Pond, though tests were not conducted to determine if this is a statistically significant trend. Results for the five acidification sampling subset of lakes indicate pH and acid neutralizing capacity (ANC) remained relatively stable both seasonally (spring/fall) and annually within each lake.

Although the results of the 2002 to 2005 lake monitoring were generally within their historical range, several samples with inexplicably elevated levels of TP and TN should be considered.

These nutrient spikes were initially attributed to episiodic loading due to heavy rainfall prior to sampling, but closer examination revealed that only one of the samples was preceded by more than 0.10" of rain in the 72 hours before sampling. It appears unlikely that rainfall was the cause of these transient high nutrient levels, and further investigation is suggested to try to establish the cause.

Attempting to determine long-term trends for specific water quality parameters is complicated by a variety of factors. Although the ANP lakes database contains records dating back to 1942, only the data collected using the current sampling and analytical protocols can be confidently used for trend analysis, and we are only now reaching the point of having a sufficient number of years of data to conduct such an analysis. Analytical methods for some analytes have changed in recent years from those used in earlier monitoring, making direct comparisons between different sets of data problematic. Analytical methods since the mid-1990s are much more uniform because the University of Maine laboratory has performed all of the analysis. In many instances, data from this period can be compared to data collected and analyzed by University of Maine researchers from the early 1980s, through 1995 that used essentially the same methodology (Kahl, 1996). However, data collected before 1980 was often analyzed using different or unknown methods.

Another factor making the analysis of trends difficult is the natural variation in annual and seasonal environmental/climatic conditions, especially in recent years. There has been great variation in seasonal and annual precipitation and temperature conditions in the past decade, as well as changes in atmospheric deposition patterns due to emission reductions as a result of amendments to the Clean Air Act in 1990. Differences in various data sets can be observed but these relatively short-term differences may not represent long-term trends.

The ANP lake monitoring program is designed to provide critical baseline data on the chemical status of ANP lakes and the temporal variability of individual constituents inherent within each water body. Because the monitored lakes reflect the broad range of lake types within ANP, these data also provide an indication of the relative status of unmonitored park lakes. Although there has not yet been a formal evaluation of the draft lake monitoring protocols, park staff and others who have informally reviewed the draft protocols believe they represent a reasonable and cost effective basis for a core long-term freshwater monitoring program.

In addition to the current lake and invertebrate monitoring programs conducted by park staff, a number of research investigations are underway to more fully characterize freshwater and estuarine systems at ANP. Several USGS research projects are investigating water budgets and nutrient enhancement in major estuaries (Nielsen, 2002), identifying and characterizing key ecological indicators and developing long-term monitoring protocols for freshwater wetlands (Guntenspurgen and Neckles, in prog.), and characterizing groundwater recharge and contamination potential (Culbertson, in prog.). The University of Maine and the USGS collaborated in a comprehensive paired watershed study to assess chemical cycling and the potential ecological impacts of atmospheric deposition on forested ecosystems (Kahl, et al, 2003). These additional water related research efforts are furnishing numerous datasets that can be integrated with other elements of the ANP long-term water monitoring program in the next few years. The Vital Signs Inventory and Monitoring Program currently being developed

17

within the National Park Service to identify key indicators of ecosystem health and a long-term monitoring program for parks will likely provide one opportunity for that integration. In preparation for this, a rigorous statistical analysis of the first 10 years of lake monitoring data, including an assessment of earlier lake monitoring data sets, is needed to determine if the current monitoring strategy will provide the data necessary to determine long-term trends in key water monitoring parameters. The park hopes to receive a full evaluation of the current monitoring program in 2006.

RECOMMENDATIONS

1) Consider more thorough investigation of nutrient (TP, TN) concentrations and sources in eutrophication group of lakes. Examine the relationship between precipitation and nutrient levels to determine the relative contributions of direct deposition and runoff to lakes.

2) Collect light profiles only in lakes too shallow for Secchi disk readings. Although each shallow lake was profiled once in 2005, increasing sampling frequency in future years would provide a more statistically robust sample size.

3) Obtain a comprehensive statistical analysis of the first 10 years of lake monitoring data collected using current protocols to determine if the current monitoring strategy will provide the data necessary to determine long-term trends in key water monitoring parameters. (Technical Assistance Request for this task was submitted to NPS Water Resources Division September 2005)

4) Obtain a formal evaluation of the draft lake monitoring protocols to determine if they represent a reasonable and cost effective basis for a ‘core’ long-term freshwater monitoring program. (Technical Assistance Request for this task was submitted to NPS Water Resources Division September 2005)

5) Continue to integrate lake monitoring data with information obtained from other aquatic monitoring and research conducted at ANP in order to better understand the current condition of the freshwater resources, as well as their responses to environmental variability and anthropogenic threats.

APPENDIX C Transparency Graphs: 1980-2005

TRANSPARENCY GRAPHS

Explanation of the Trophic State Index (TSI) (from Heiskary and Lindbloom, 1993) The trophic state index, developed by limnologist Dr.Robert Carlson, is one means to evaluate the trophic status of a lake and to interpret the relationship between total phosphorus, chlorophyll a, and Secchi transparency. TSI values are calculated as follows:

Secchi disk TSI = 60-14.41 ln(Secchi depth in meters)

Interpretation: TSI < 30: Classic oligotrophic lake- clear water, hypolimnion well-oxygenated throughout the year. TSI 30-40: Deeper lakes exhibit classical oligotrophy, shallower lakes may become anoxic in the hypolimnion during the summer. TSI 40-50: Water relatively clear, but increasing probability of anoxia in hypolimnion during summer. TSI 50-60: Lower boundary of classic eutrophy: Decreased transparency, anoxic hypolimnia duning the summer, macrophyte problems evident, warm-water fisheries only. TSI 60-70: Dominance of blue-green algae, algal scums probable, extensive macrophyte problems. TSI 70-80: Heavy algal blooms possible throughout the summer, dense macrophyte beds, but extent limited by light penetration. Often would be classified as hypertrophic. TSI >80: Algal scums, summer fish kills, few macrophytes, dominance of rough fish. An increase of ten units represents a doubling of algal biomass
