DNR fish survey, 2025

Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.

A summer trap net survey was conducted in Maple Lake by Lake Biological Monitoring and Assessment program staff beginning on August 4, 2025. Twelve trap nets were set along the shoreline in locations that encompassed multiple habitat types. Trap net sampling captured 12 species of fish, including two species that are intolerant of disturbance (i.e., Rock Bass and Smallmouth Bass). Bluegill comprised a majority of the catch by number, while Walleye and Yellow Bullhead comprised a majority by biomass. The trap net and nearshore data from July 2025 were combined with gill net data from a June 2025 survey to describe the fish community and provide a fish-based IBI (FIBI) score. The survey results will be considered when the biological health of the lake is assessed during the Chippewa River Watershed assessment process, which will be completed in coordination with MN Pollution Control Agency. Maple Lake provides recreational angling opportunities for Sunfish, Largemouth Bass, Northern Pike, and Walleye. Smallmouth Bass are also present in Maple Lake. You can help protect the fish community in Maple Lake by reducing runoff, maintaining natural shorelines, and preventing the spread of invasive species.
