History & Status of the Fishery
A targeted survey of the nearshore fish community in Wilmert Lake was conducted by Fisheries Index of Biological Integrity (IBI) Program Staff starting June 24, 2019. Ten sampling sites were evenly spaced around the lake and each was sampled by backpack electrofishing and seining with a 50-foot seine. Nearshore sampling captured 9 native species of fish. None of these species are intolerant of disturbance and four species are tolerant of disturbance (Bigmouth Buffalo, Black Bullhead, Fathead Minnow, and Orangespotted Sunfish).
Data from this targeted nearshore survey is combined with trap net and gill net data from an August 2018 standard survey to describe the fish community and provide a Fish-based Index of Biological Integrity (FIBI) score. The FIBI uses fish community data to measure a lake's health, and the types of fish species present can help identify any stressors that may be negatively affecting the lake environment. In Minnesota lakes, certain fish species cannot survive without clean water and a healthy habitat (e.g., Iowa Darter and Rock Bass), while other species are tolerant of degraded conditions (e.g., Black Bullhead and Fathead Minnow). The FIBI score, composed of several fish community diversity and composition metrics, indicates the overall health of a lake by comparing it to what is expected for a healthy lake. For additional information on the FIBI, search for "lake index of biological integrity" on the mndnr.gov website.
Data from this survey will contributed biological information about the health of the fish community in Wilmert Lake to the Blue Earth River Watershed assessment of surface waters process completed in coordination with MN Pollution Control Agency.
