I. INTRODUCI10N

Cascades Environmental Services, Inc. (CES) and Hydro West negotiated instream flows for rainbow trout winter rearing, spawning and summer rearing in both Hancock (FERC Number 9(25) and Calligan (PERC Number 8864) creeks. Rainbow trout spawning timing

.in these creeks was uncertain and assumed to occur in June and July. To resolve this issue, CES developed a study plan in cooperation with Hydro West Group and Dr. Hal Beecher of the Washington Department of Wildlife (WDW). The objective of the study was to detennine the central 80% spawning timing of the rainbow trout populations in the bypass reaches of Hancock and Calligan creeks.

II. METHODS

CES used two different techniques to determine spawning timing in the study reaches. The most common methodology for calculating the incubation and emergence period of eggs and fry uses temperature units. One Daily Temperature Unit (DTU) equals 1°F above freezing (32°F) for a 24-hour period. For example, if the water temperature for the first day of incubation is 56~, it would contnbute 24 DTU. Temperature units required for a given species of fish are not fixed. They will vary with different water temperatures and are affected by fluctuations in temperature (piper et al. 1982).

Another commonly used indicator of the onset of trout spawning and summer rearing activity in the Cascade Mountains is· the increase in stream temperatures to above 8°C, or 46.4°F (Campbell and Neuner 1985a). Conversely, winter behavior and changes in depth and velocity preferences typically begin when stream temp'eratures drop below this threshold (Campbell and Neuner 1985b).

CES inst~lled thermographs to record air and water temperatures in April at three different locations: 1) downstream of the outlet to Hancock Lake on Hancock Creek; 2) downstream of the outlet to Calligan Lake on Calligan Creek; and 3) at the IFIM site on Calligan Creek. Data Loggers recorded mean air and water temperatures every two hours. We downloaded the data from the sites every 6 - 8 weeks.

We surveyed Calligan and Hancock creeks once per week from June through September, with a final survey in October. CES snorkeled the streams to observe fish and note the onset of fry emergence. After we documented fry emergence, we electroshocked index areas in both streams to. sample fry populations, noting length and species when possible. We developed cumulative fry emergent timing curves for each stream. CES determined the central 80% of the emergence timing curve, per agreement of the parties, and we backcalculated rainbow trout spawning ~mlng using fry emergence data and temperature information gathered from the Data-pods.

m. RESULTS AND DISCUSSION

A Hancock Creek

1. Water Temperature.

Table 1 descnbes minimum, mean and maximum air and water temperatures at the gaging site below Hancock Lake. Water temperatures at the gaging station varied from a 2-hour mean low of 39.'?F on April 18 to a 2-hour mean high of 7430f" on July 23. Mean water temperature of the period of record was 55.2~.

The gaging station on Hancock Creek is located in a broad, flat, slow-moving section of stream below the lake outlet which receives a great deal of solar radiation. The remainder of the stream, however, travels through much narrower, steeper, and confined channels that are often shaded. From April through mid-June, temperatures at the IFIM site, index areas and gage station were fairly equivalent (Figure 1a). By June 23, however, temperatures in the bypass reach began to deviate from temperatures recorded at the gage station by as much as 12°F (Figures Ib-c). When discrepancies existed, CES used temperatures recorded in the bypass reach for the study calculations.

2. Fry Emergence and Growth

CES started snorkeling Hancock Creek on June 1. We observed several pairs of rainbow trout, but could find no evidence of newly-rlug redds. When we first observed fry near the outlet to the lake and the bypass reach on June 22, CES began electroshocking the stream to collect fry abundance and length data.

Table 2 summarizes trout fry observations in Hancock C-!"eek. We conducted a length frequency analysis and Figure 2 depicts cumulative emergence timing of rainbow trout in Hancock Creek by size classes (35mm, 40mm and 45mm). We used the central 80% of the run timing curveS, discarding the "tails." Using this methodology, CES determined the central 80% emergence timing of rainbow trout fly « = 35mm) spanned the period July 13 - 27.

3. Spawning Timing of Rainbow Trout in Hancock Creek.

Table 3 presents Daily Temperature Units (DTU) at the Hancock Creek gaging station and the bypass reach. In Hancock Creek, where mean water temperatures remain between 500F and 600F during the spawning and incubation period, approximat~ly 765 DTU are required for emergence of rainbow trout fry (Leitritz and Lewis 1976).

calculating 765 DTU's, CES estimated that the majority of rainbow trout spawned in the bypass reach from June 8 - 25, 1991. If we were to increase the size of the fly used in the analysis « = 45mm), spawning timing would extend from June 8 through July 18, 1991.

As we mentioned earlier in this report, Campbell and Neuner (1985a) demonstrated that temperatures exceeding 8°C (46.4°F) could trigger spawning and summer rearing behavior in Western Washington, Cascade Mountain trout populations. Table 5 shows 15-day mean temperatures in Hancock Creek below the lake outlet and in the bypass reach.

Temperatures rose to exceed 46.4°F during the 15-day period beginning May 1; however, the temperature patterns we observed in 1991 were atypical. Air temperatures usually begin to increase in late May, resulting in snow melt and runoff through the end of June or the beginning of July. Stream temperatures will typically remain low throughout the end of the snow melt period, then increase as streamflow levels drop and air temperatures rise. In 1991, however, the climate remained cool and rainy until the beginning of July. Consequently, the persistent rainfall gradually melted the snowpack throughout the entire spring/early summer period. Stream temperatures remained ,higher than would have been expected in a typical spring and spawning occurred earlier in 1991 than in a more "nonnal" year.

4. Recommendations

CES recommends that the rainbow trout spawning and summer rearing flows (20 cfs) be required in Hancock Creek from June 16 through October 15 of each year. This flow regime allows adequate protection for rainbow trout spawning in an atypical year (such as 1991) while providing flows which would maximize habitat availability in years when we would anticipate streamflows and temperatures to be more consistent with observed trends. Winter instream flows of 5 cfs would be implemented from October 16 ~~~ June 15 per agreement of all the parties.

B. Calligan Creek

Calligan Creek has a subversion zone downstream of the lake outlet. The creek seeps into the ground near the lake outlet and dries up during most summers. Nearly· one mile downstream, the water re-emerges as a spring; it maintains a relatively constant and stable temperature regime during the summer months.

1. Water Temperature

CES installed two temperature monitoring sites on Calligan Creek: 1) 100 yards downstream of the lake outlet near the subversion zone; and 2) at the IFIM site, immediately below the spring.

Table 6 presents minimum, mean and maximum air and water temperatures at the gaging site below Calligan Lake. Water temperatures varied from a 2-hour mean low of 38.SOF on October 4 to a 2-hour mean high of 6O.goF on June 30. Mean water temperature for the period of record at the site was 49.00F; however, water temperatures from July 1 through September 30 were excluded from the analysis because the upper stream was dewatered. .

Table 7 displays minimum, mean and maximum air and water temperatures at the IFIM site, immediately downstream of the spring. Mean water temperature for the period of record was 46.6°F. Stream temperatures varied from a 2-hour low of 43.1°F on April 18 to a high of 53.g<>F on August 17. Mean daily temperatures deviated < 5°F during the entire period of record (Figures 3a-c), indicating the spring maintains fairly constant temperatures. Water temperatures in the bypass reach tended to be higher when. there was still overland flow below Calligan Lake in the subversion zone and these waters and the spring mixed at the IFIM site. As the flows from the lake diminished and gradually disappeared, however, water temperatures at the IFIM site decreased and remained low.

2. Fry Emergence and Growth

CES started snorkeling surveys on June 1 in Calligan Creek. When we first observed over 70 fry near the outlet to the lake on June 22, CES began electroshocking the stream to collect fry abundance and length data. We did not observe any fry in the bypass reach on this date, but water temperatures in the study reach were colder.

Table 8 Summarizes trout fry observations in Calligan Creek. We conducted a length frequency analysis and charted emergence timing of those trout we observed in the bypass reach. CES excluded those fish captured near the lake outlet from the analysis.

We measured and identified all captured trout fry, when possible. In some cases, fry escaped before we could determine the species and length. In these instances, we estimated the length, left the species unknown, and excluded the ·observation from species-specific analysis. We did conduct an analysis, however, where we included all fish observed, regardless of species.

Figure 4 portrays cumulative emergence timing of rainbow trout in Calligan Creek by size classes (3Smm, 40mm and 45mm, N = 62). We used the central 80% of the run timing curves~ discarding the "tails." Using this methodology, we determined the

central 80% emergent timing of rainbow trout fry (< =35mm) ranged from July 5 -August 17.

Figure 5 shows cumulative emergence timing of those fish identified as cutthroat trout and measured by size class (N = 10). The central 80% emergence timing of these fish extended from July 16 through August 17.·

Figures 4 and 5 display only those fish identified as either rainbow or cutthroat and measured. It is often difficult to determine the species in young trout, particularly newly-emerged fly. There were several fry, however, that we were not able to identify to species or measure. We estimated the lengths of these fish to the nearest 5 mm. Figure 6 presents the pooled emergent timing of all the trout we found in the bypass reach (N = 104). These data indicate the central 80% emergence timing of the fry extends from July 15 through August 18 in the bypass reach of Calligan Creek.

3. Spawning Timing of Trout in Calligan Creek

Table 9 shows Daily Temperature Units for Calligan Creek at the gaging station and the bypass reach. In Calligan Creek, where mean water temperatures remain between 44°F and 49OP, rainbow trout require approximately 850 DTU for incubation through emergence, while cutthroat trout require 1100 DTU's.

Table 10 presents spawning and fry emergence timing of rainbow trout in the CalJigan Creek bypass reach. By using the central 80% fry emergence curve and backcalculating 850 DTU's, CES estimated that the majority of rainbow trout spawned in the bypass reach between May 12 and June 20, 1991. If we were to increase the size of fish used in the analysis «= 45mm), spawning time would extend from May 22 through July 7, 1991.

CES estimated that peak spawning of cutthroat trout occurred from May 7 through June 7, based on 1100 DTU's and the fry emergence curve we developed. If we were to increase the size of fish used in the analysis «"= 45mm), cutthroat spawning occurred between May 11 - June 8. The sample size, however, was only 10 fish.

As mentioned earlier in this report, it is often difficult to distinguish between rainbow and cutthroat trout during the early life history stages, particularly when the fish are newly emerged fry. Consequently, we pooled all obsetvations of newly emerged trout. We consider this a vaiid technique because it eliminates errors in identification, ·and allows us to analyze a larger sample size. Through the use of the fly emergence curve and back-ca1culating 850 DTU's, CES determine that rainbow trout « = 35mm) spawning occurred from May 23 through June 23. If we were to increase· the size of the fish used in the analysis « = 45mm), spawning time would extend from May 24 - Ju1y 4 in 1991.

Campbell and Neuner (1984a), as mentioned earlier in this report, demonstrated a correlation"between fish behavior and stream temperatures. Table 11 shows 15-day mean water temperatures in Calligan Creek at the IFIM site. Temperatures increased to above 8°C (46.4OP) during the 15-day period beginning May 15, 1991. This date c~ITesponds closely with the dates that spawning commenced.

Conversely, when temperatures drop below 8°C, trout revert to a more dormant, less active behavior. Data from the gage in the bypass reach indicate temperatures drop below this threshold by the end of August, and that "winter conditions" exist as early

.. as September 1 in the bypass reach.

4. Recommendations

CES recommends that the spawning flows (15 cfs at the IFIM site and 2 cfs at the diversion) for rainbow trout in Calligan Creek begin on May 15. This flow regime allows for complete protection of th'e central 80% of the spawning population, while granting an additional 9 days of increased flows for the front "tail" of the curve. Instream flows are different at the diversion and the IFIM-site because of the inflow from the spring.

Winter conditions (i.e., water temperatures decreasing to below SOC) exist as early as September 1 in the Calligan Creek bypass reach because of the nearly constant temperature of the spring. The summer of 1991, however, was extremely dry, and there was no overland flow from the lake until late October.

Therefore, warmer waters from the lake did not mix with the colder spring waters. It is possible that in wetter years the stream would not dry up and that the warmer surface water from the lake, when merged with the colder spring waters, would elevate stream temperatures in the bypass reach. For this reason, CES recommends that the winter curves take effect from September 15 through May 14 of each year: 2 cfs are required at the diversion and 6 cfs at the IFIM site during the winter period.

IV. AGREEMENTS

Instream flow regimes for Hancock and Calligan creeks have been agreed to by all the parties. The details of those agreements are found in the October 30, 1991 summary of consultation. In summary, the agreements are:

Instrearn Stream Flow Life Stage Date

Hancock Creek 5 cfs Winter Oct. 16 - June 15

20 cfs Spawning/Summer June 16 - Oct. 15

Calligan Creek 2 cfs * Winter Sept. 15 - May 14 6 cfs **

2 cfs * Spawning/Summer May 15 - Sept 14 15 cfs **

* At the Diversion ** At the IFIM Site
