  18. Major Land Uses in The Great Lakes

  19. Because of Land Use, 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 climate change.) And Lake Erie is still biologically the most productive of the Great Lakes—And always will be!!

  20. 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

  21. 80:10:10 Rule • 80% of water from upper lakes • 10% direct precipitation • 10% from Lake Erie tributaries • Maumee • Largest tributary to Great Lakes • Drains 4.5 million acres of ag land • 3% of flow into Lake Erie

  22. Lake Erie’s 7 Biggest Problems/Issues (see Twine Line, Spring/Summer, 2012) • Sedimentation • Phosphorus and nutrient loading • Harmful algal blooms • Aquatic invasive species • Dead Zone • Climate Change—Makes the others worse • Coastal Economic Development

  23. Lake Erie Stats Drinking water for 11 million people Over 20 power plants Power production is greatest water use 300 marinas in Ohio alone Walleye Capital of the World 40% of all Great Lakes charter boats Ohio’s charter boat industry is one of the largest in North America $1.5 billion sport fishery One of top 10 sport fishing locations in the world Most valuable freshwater commercial fishery in the world Coastal county tourism value is over $11.5 billion and 117,000 jobs

  24. Lake Erie: One of the Most Important Lakes 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 5 states, a province, and 2 countries. Best example of ecosystem recovery in world.

  25. June 22, 1969

  26. Impact of Ecosystem Recovery (rebirth) Ohio walleye harvest 112,000 in 1976 to over 5 million by mid-80s 34 charter fishing businesses in 1975 to over 1200 by mid-80s and almost 800 today 207 coastal businesses to over 425 today

  27. What brought about the rebirth (dead lake to Walleye Capital)? Phosphorus reductions from point sources (29,000 metric tons to 11,000);and agriculture helped!

  28. Why did we target phosphorus? Normally limiting nutrient in freshwater systems P reduction is best strategy ecologically and economically Reducing both P and N would help

  29. Algae are tiny plant-like organisms that live in water There are hundreds of species of algae in Lake Erie. Most are beneficial. • Source: Tom Bridgeman, UT

  30. Major groups/kinds in Lake Erie Diatoms Greens Blue-greens (Cyanobacteria) • Source: Tom Bridgeman, UT

  31. Impacts of Increased Phosphorus Concentrations • HABs—If P concentrations are high (regardless of the source, Ag, sewage, etc.) and water is warm, we will have a HAB (nitrogen concentration will likely determine which of the ~10 species bloom) • Nuisance Algae Blooms • Cladophora—Whole lake problem. An attached form. • Winter algal blooms • Dead Zone in Central Basin

  34. Microcystin Concentrations 1 ppb WHO drinking water limit 20 ppb WHO swimming limit 60 ppb highest level for Lake Erie till 2011 84 ppb highest level for Grand Lake St. Marys till 2010 2000+ Grand Lake St. Marys 2010 1200 Lake Erie Maumee Bay area 2011

  35. Reference Dose = amount that can be ingested orally by a person, above which a toxic effect may occur, on a milligram per kilogram body weight per day basis. Toxicity of Algal Toxins Relative to Other Toxic Compounds found in Water Toxin Reference Doses Dioxin (0.000001 mg/kg-d) Microcystin LR (0.000003 mg/kg-d) Saxitoxin(0.000005 mg/kg-d) PCBs (0.00002 mg/kg-d) Cylindrospermopsin (0.00003 mg/kg-d) Methylmercury(0.0001 mg/kg-d) Anatoxin-A (0.0005 mg/kg-d) DDT (0.0005 mg/kg-d) Selenium (0.005 mg/kg-d) Botulinum toxin A (0.001 mg/kg-d) Alachlor (0.01 mg/kg-d) Cyanide (0.02 mg/kg-d) Atrazine (0.04 mg/kg-d) Fluoride (0.06 mg/kg-d) Chlorine (0.1 mg/kg-d) Aluminum (1 mg/kg-d) Ethylene Glycol (2 mg/kg-d)

  40. HABs in 2013 • NOAA forecast in partnership with OSU Sea Grant and Stone Lab, Heidelberg U, and U of Toledo • Based on the total phosphorus load from the Maumee River 1 March to 30 June • Issued at Stone Lab press conference on 2 July

  41. NOAA issued the first forecast in 2012. 2012 Forecast (mild bloom) and observed. Measured 2012 Forecast

  42. 2013 Forecast: Significant bloom.similar to 2003, much milder than 2011 2013

  43. 2013 prediction for western Lake Erie:similar to 2003, <1/5 of 2011, 2X 2012 2011 for comparison 2013 may resemble 2003 low medium high concentration

  45. Target Loads to Solve Problem • Leading subcommittee of the Ohio Phosphorus Task Force to identify both spring and annual target loads of both total P and DRP to prevent or greatly reduce HABs • Target is 40% reduction

  46. Nutrient Loading: Expect improvement • Scotts P removal from over the counter fertilizer bags • CSO’s moving in right direction (too slow?) • Detroit sewage—hopefully in compliance—but bankrupt • Frequency of severe storms continues to go up • Ag—expect improvement • Farm Bureau is supporting efforts to reduce P • Majority of farmers now accept responsibility • Certification programs being developed • 4R Program • Recommendations • Don’t apply more fertilizer than needed • Don’t apply on frozen or snow covered ground • Don’t broadcast, incorporate into soil • Don’t apply before when rain in immediate forecast
