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.


Continuous discharge data collection from 13 gages will be used in pollutant load calculations. SWAT models for the tributaries are currently under development.
