State of the Great Lakes 2019 Highlights Report

Updated on: July 21 2020

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.

Soil and Water Assessment Tool (SWAT) Lower Maumee SWAT Model Summary

Updated on: August 14 2019

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.

The Heidelberg Tributary Loading Program

Updated on: June 5 2018

Heidelberg University’s National Center for Water Quality Research collects and analyzes approximately 450-500 water samples for pollutants at each monitoring station each year. From that information it calculates annual pollutant loads from each station and the loads of nutrients, sediments and pesticides delivered to Lake Erie or the Ohio River.
