Water Quality Monitoring and Assessments

Surface water bodies in Cook County are used for stormwater detention, domestic and industrial uses, recreation, and commercial navigation. However, the bathymetry (elevation of the bottom surface) of most water bodies in Cook County has not been measured or mapped comprehensively. Similarly, water quality in most of these water bodies is unknown.

Eight nutrient monitoring stations were established in 2015 to continuously monitor nutrient and sediment concentrations and loads in support of the Illinois Nutrient Loss Reduction Strategy. This site provides current and historical monitoring information for the eight nutrient monitoring stations.
