7. Where are we today? Today, almost 2/3 of water bodies now meet Clean Water Act uses and goals. Recreation on Lake Erie is worth $3 billion a year. Jet skis and water taxis replaced fire patrol on the Cuyahoga.
16. Aquatic Life Require Dissolved Oxygen Minimum range in dissolved oxygen for survival and reproduction Milligrams per liter (mg/L) > 3 to 8 > 3 to 6.5 > 4 to 10 > 2 to 4

http://www.csuohio.edu/cestp/sol/history/pictures.html The burning Cuyahoga highlighted the need to clean up America's rivers and provided an important impetus for the Clean Water Act of 1970.
Bacteria levels in Toledo area streams are too high for safe swimming nearly a third of the time. (Maumee River Basin Area of Concern Remedial Action Plan Recommendations) DSC01048 – CSO warning sign at Cullen Park Bacteria is monitored by testing for E. Coli. Probably aware of the toxic strain of E. Coli due to food issues, however, not all strains of E. Coli are a problem (e.g., you have thousands inside your intestine as do other warm-blooded mammals). Therefore, just because E. Coli are in the water, doesn’t mean there’s sewage or its unsafe. Just that there’s a risk that there may be a harmful virus, bacteria strain, etc. in the water.
