Tributary monitoring data was used by the USGS, NCWQR, USEPA and ECCC to calculate spring and annual phosphorus loads. Annual loads were estimated at the river mouth using tributary monitoring and municipal discharge data from NCWQR, OEPA, MDEQ, USEPA, USGS, ECCC, and OMECC.
The U.S. Environmental Protection Agency (U.S. EPA) has a page dedicated to cyanobacterial HABs, including information on health effects, causes and prevention, and state-specific resources.
Ohio outlines actions to reduce phosphorus in Lake Erie.
Indiana outlines actions to reduce phosphorus in Lake Erie. The button below provides the Action Plan, but for additional information on the plan development process, Indiana's DAP website outlines these details.
The Ohio Lake Erie Phosphorus Task Force Phase II effort built on the work of the 2010 Phase I report by incorporating newly available information and including more stakeholders with additional areas of expertise. The purpose of Phosphorus Task Force Phase II is to 1) develop reduction targets for total and dissolved reactive phosphorus that can be used to track future progress, and 2) develop policy and management recommendations based upon new and emerging data and information.
The Lake Erie Protection & Restoration Plan 2020 reflects the state of Ohio’s priorities to protect, preserve and restore Lake Erie. The purpose of the plan is to identify the state’s strategic direction for Lake Erie and the Lake Erie watershed to achieve established environmental, recreational, and economic goals.
Representatives from the United States Environmental Protection Agency and Environment and Climate Change Canada presented on the ongoing efforts to manage excess phosphorus loads leading to toxic and nuisance algal blooms and hypoxia in Lake Erie. The webinar provided a brief overview of information and updates on work under the Nutrients Annex of the Great Lakes Water Quality Agreement (GLWQA) and included presentations by experts from the Nutrients Annex Subcommittee.
The United States and Canada adopted phosphorus load reduction targets to combat Lake Erie algal blooms.
The Governments of Canada and the United States are pleased to release the 2019 State of the Great Lakes Highlights Report, which provides an overview of the status and trends of the Great Lakes ecosystem. Overall, Great Lakes water quality is assessed as “fair and unchanging.” While progress to restore and protect the Great Lakes has occurred, including the reduction of toxic chemicals, challenges cited in the report include invasive species and excess nutrients that contribute to toxic and nuisance algae.
