Lake ID

Minnesota Department of Natural Resources (MNDNR) site ID 10000400. This link provides information on lake location, morphometry, and fisheries. 

Chaska Lake is a 49-acre (20-hectare) lake near the city of Chaska, Minnesota, and is part of the Minnesota Valley National Wildlife Refuge. Chaska Lake is in the floodplain of the Minnesota River. Floodplain lakes, with their complex hydrology and ecosystems, are subject to periodic flooding that introduces water, sediment, and aquatic life. 

Water quality monitoring activities for floodplain lakes have been either eliminated or reduced because of the regular intrusion of water from the Minnesota River. Sediment and paleolimnological assessments have been periodically completed to understand the quantity and quality of sediment deposition in some of the floodplain lakes from the Minnesota River. Information about depth, water chemistry, or vegetation was not found for Chaska Lake. 

Monitoring Data


Measurements of transparency (a measure of water clarity) and other indicators of lake productivity were taken from 2017 to 2020 and are provided by the University of Minnesota LakeBrowser (UofMN, 2021). The transparency of Chaska Lake is generally greater than 0.5 meters (1.5 feet). Many of the readings exceed the 1.0 meter (3.3 feet) criteria for shallow lakes in Minnesota (Statutes, 2021).
