Specific activities identified by Lake Erie states, the province, and federal governments within Domestic Action Plans are tracked on ErieStat as Investments.  Tracking these investments will enable the adaptive management of phosphorus control efforts and eventually, provide “big picture” views of phosphorus control Progress.

Michigan: Identify priority areas and actions in Michigan’s portion of the Maumee River Watershed for phosphorus reductions
Updated on: November 8 2019

Only a small portion (about 7 percent) of the Maumee watershed lies within Michigan’s borders. Michigan is partnering with Indiana, Ohio, the U.S. EPA, and the U.S. Geological Survey to ensure appropriate monitoring of the watershed. Though continued monitoring is needed, initial monitoring and analysis has revealed that certain parts of the Maumee watershed in Michigan have higher phosphorus concentrations than others.

New York: Lake Erie tributary monitoring
Updated on: September 23 2019

The Lake Erie watershed has been identified through New York State Department of Environmental Conservation's Clean Water Planning Initiative as a high priority for water quality improvement, and Lake Erie is currently the focus of binational efforts under Annex 4 (Nutrients) of the Great Lakes Water Quality Agreement (GLWQA) to assess and reduce nutrient loadings. The objectives of this project are:

  • To collect baseline nutrient and sediment water quality data along with discharge that can be used for model development;
  • To develop a watershed model that will help focus future water quality improvement efforts in the basin, and;
  • Aid in loading calculation and future regional target-setting efforts for nutrient reduction.

New York: Nuisance and harmful algal bloom research
Updated on: September 23 2019

New York State has established and implemented various programs and initiatives to research water quality issues throughout the state relating to Harmful Algal Blooms. New York State is also committed to participating in the Great Lakes Water Quality Act’s (GLWQA) Annex 4 Cladophora initiatives and research. New York will continue ongoing research efforts on algal blooms both within Lake Erie and other New York waters.

New York: Development of the Nine Element Plan

Updated on: September 23 2019

New York State was not required to prepare a Domestic Action Plan (DAP), as binational phosphorus targets have not been established for the eastern basin under the Great Lakes Water Quality Agreement (GLWQA). However, the Department of Environmental Conservation (DEC) will develop a Nine Element Plan to maintain the “Interim Substance Objective for Total Phosphorous Concentration in Open Waters of Eastern Basin of Lake Erie.”
