This interactive map viewer identifies potential causes of impairment and pollutant sources that need to be controlled to achieve desired phosphorous load reductions and reduce the Harmful Algal Blooms in the Western Lake Erie Basin.
The United States Department of Agriculture - Agricultural Research Service (USDA-ARS) developed this computer-generated model to estimate the nutrient loads coming from sub-basins in areas with insufficient water quality monitoring data. The model has been run in areas like the Lower Maumee where there is enough water quality monitoring data to calibrate the program.
This strategy brings together diverse nutrient management activities for point sources and nonpoint sources across the state. It documents the progress of ongoing activities implemented by federal, state, or local agencies and identifies outstanding needs.
Québec’s source water protection efforts are advanced under the guidance of this policy document. It incorporates lessons learned since the passing of the 2002 Water Policy and was created with input from 140 water sector organizations and hundreds of public comments. The strategy will be implemented through three successive action plans, with the first plan outlining proposed source water protection activities from 2018 to 2023.
