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.

Program Goals and Objectives:
• Improve science education, link research scientists
and managers, improve management decisions,
facilitate the development of collaborative research
projects to address management needs, enhance
public understanding of Great Lakes issues.
• Solve problems, prevent them from happening,
minimize their impact, protect human health, and
maximize the value of Lake Erie.
• Support the LaMP and the CSMI.

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

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

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
![Page 52: Research, Education, and Outreach Efforts on Critical Lake Erie Issues](https://reader033.vdocuments.net/reader033/viewer/2022042814/5549862db4c90554648b4f1c/html5/thumbnails/52.jpg)
Ohio Sea Grant College Program
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.

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)

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!

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

How do we close the door?

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.

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

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

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

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)

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”

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!!

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

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
