Most Important Lake In the World?• “Its our lake. I see it every day. It can’t be the most

important lake in the world.”

• Dead lake image of 60s and 70s.

• Poster child for pollution problems in this country.

• But, most heavily utilized of any of the Great Lakes.

• Shared by 4 states and 2 countries.

• Best example of ecosystem recovery in world.

Lake Erie Cross Section


41

80:10:10 Rule

80% of water from upper lakes

10% from Lake Erie Tributaries

10% direct precipitation


42

Great Lakes

Lake Superior: Most Water

Lake Huron: Longest shoreline

Lake Michigan: Largest US population

Lake Erie: Most productive and most fish—smallest volume

Lake Ontario: Largest Canadian population—smallest area


43

Most agriculture of the Great Lakes.


44


45

As a Result, Lake Erie Gets:

More sediment

More nutrients (fertilizers and sewage)

More pesticides

(The above 3 items are exacerbated by storms, which will be more frequent and severe due to global warming and climate change.)

And is still biologically, the most productive of the Great Lakes


46

50:2 Rule(Not exact, but instructive)

Lake Superior: 50% of the water and 2% of the fish

Lake Erie: 2% of the water and 50% of the fish

Lake Erie’s Biggest Problems

+ Sedimentation/Water Clarity/Dredging

+ Nutrients and Phosphorus

+ HABs—Harmful Algal Blooms

+ Dead Zone

+ AIS—Aquatic Invasive Species

+ Climate Change/Lake Levels/Severe Storms


50

Sediment Entering Lake Erie—4/2/08

50


51

Impacts of Sedimentation

Water quality is reduced

Nutrients and contaminants enter the Lake attached to sediment particles

Can trace Maumee River sediments over Niagara Falls within one year

Maumee River is largest single source—should not allow open lake disposal where it is guaranteed to resuspend


52

Why does Lake Erie get the most

sediment?

Because it has the most agriculture in its basin.

Maumee River brings more sediment into Lake

Erie than all tributaries carry into Lake Superior,

and Lake Superior is 20 times larger in volume

than Lake Erie.


53

Nutrients and Phosphorus


54

Why does Lake Erie get most nutrients?

• Because it has the most agriculture in its basin.

• Few forests

• Wetlands gone

• Large human population—water treatment,

septic tanks, sewage treatment (or lack thereof)

Impacts of Increased Phosphorus Concentrations

+ Microcystin levels 60 times WHO

+ Cylindrospermopsis

+ Cladophora—Whole Lake Attached

no longer true.)

HAB Requirements

Warm water (summer problem)

High phosphorus levels (and now high nitrogen)

Zebra/quagga mussels (remove competition)


63

HABs:Western Basin ProblemBut Contribute to Oxygen Demand inthe Central Basin, i.e.the Dead Zone


64

Dead Zone:Central Basin Problem

68

Nutrients and organic material in sewer discharges and CSOs contribute directly to HABs and the Dead Zone, but it is highly likely that non-point loading from agriculture is the predominant factor!


69

Efforts to prevent/reduce CSOs will improve the Dead Zone and reducebeach closings!


70

AISOver 180 species in Great Lakes

75% since Seaway opened

Zebra and quagga mussels

Phragmites and loosestrife

Round gobies

Next?—Silver Carp??

How do we close the door?


71

Because Lake Erie is the southernmost, shallowest, warmest, and most nutrient-enriched of the Great Lakes, it is likely that AIS will always present the greatest problem, and have the greatest impact, in Lake Erie.


72

Climate change is real and will make these problems worse!

• Warm water favors HABs

• Warm water increases oxygen depletion rates

• More severe storms will resuspend more sediment and increase erosion and sediment loading

• Lake levels uncertain


73

Power Production Impacts

No Free Lunch

Wind

+ Bird Mortality

Coal or Nuclear

+ Cooling water impacts on fish

+ Mining impacts

+ Air pollution impacts

+ Volume of material—fuel and waste

The Forecast:Increased sedimentation—lower water clarity

(also means reduced coastal property values)

Lower Lake Levels

More nutrients—algal mats, flies, HABs and toxins

AIS—new one every 8 months

Dead Zone—bigger and longer lasting

Water treatment costs will increase

Lake Erie will continue to be the most important lake in the world


76

Reasonable Goals+ Elimination of beach closures and water quality

improvements

• CSO reductions will help

• Everything else will likely be worse for Water Quality

+ Elimination of Dead Zone

• Important to drinking water quality

• May not be possible

+ Elimination of HABs

• Very important to human health

• Can be achieved

• Will also improve Dead Zone and beaches


77

What Can You Do? IDon’t wait for someone else to solve the problem.

Be part of the solution. Join and support local environmental organizations, e.g.

• Friends of Stone Laboratory

• Bioneers

• Cleveland Museum of Natural History

• Cleveland Botanical Garden

• Lake Erie Nature and Science Center

• Great Lakes Science Center

• A watershed protection group

• A Remedial Action Plan (RAP)


78

What Can You Do? IISupport improvements to public sewer systems

that eliminate CSOs—your rates will increase!

Reduce runoff from your property

Reduce your carbon footprint

Reduce your water and electrical usage

Follow guidelines to prevent introduction of AIS

Become a “Clean Boater”

Dock your boat at a certified “Clean Marina”


79

What Can You Do? III

Make sure your septic tank is working properly

Be vocal and tell your elected officials to support environmental programs

Volunteer for beach and shoreline cleanups

Help protect and restore wetlands

Use buffer strips on your farm

Results and Key Points from Discussion—1

• Managers should focus on bioavailable P, not total P

• P limitation of algae may be decreasing

• High N levels may be pushing algae away from

Anabaena and Aphanizomenon and toward Microcys.

• Implications

+ Algae is N limited

+ P loading has gone up so much that it is no longer limiting

+ REDUCING P LOADS SHOULD STILL BE GOAL!!


82

Results and Key Points from Discussion—2

• Increased turbidity from Maumee River sediment is

advantageous to harmful algal blooms (Microcystis sp.)

• Microcystis is found in sediment prior to bloom and

sediments may be acting as a source

• Microcystis concentrations were highest in Aug., but found as

early as April

• Lyngbya concentrations highest in June – Aug and at 2-4 m

depths

• Many forms of Microcystis—not always producing toxin


83

Results and Key Points from Discussion—3• Stratification of P in soil samples is important

• Direct runoff of surface applied P is a factor

• In the CB and EB and looking from nearshore to offshore: P concentrations go down, we are P-limited, and there may be more P in sediment of CB than WB

• STP is a good indicator of P transport risk

• Phosphonate can be used by algae

• Changes in STP in last decade:+ Input and output balanced in Ohio

+ STP levels have remained steady or gone down in most counties

+ Mercer County with many CAFO’s is a notable exception
