Field note · Minnesota stocks by year, not by truck day: walleye fry go in within weeks of ice-out, fingerlings and yearlings mostly in fall, and stream trout in spring and fall. A row here means the fish went in during that year; DNR adds the year's rows after the fact, so the current year can look empty until winter.

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 targeted survey of nearshore fish species in Big Too Much Lake was conducted on June 27-29, 2022, by Index of Biological Integrity (IBI) Program staff. Sampling sites were evenly spaced around the lake, and each was sampled by backpack electrofishing and seining with a 50-foot or 15-foot seine, where possible. Backpack electrofishing was completed at all 10 sampling stations. Similarly, a 50-foot seine was used to sample six stations, a 15-foot seine was used to sample two stations, and site conditions prevented the use of a seine at two stations. Nearshore sampling captured 17 species of fish including six species that are intolerant of disturbance (i.e., Banded Killifish, Blackchin Shiner, Blacknose Shiner, Iowa Darter, Mimic Shiner, and Rock Bass) and one that is tolerant of disturbance (i.e., Fathead Minnow). A concurrent summer trap net survey was conducted by IBI Program Staff. Nine trap nets were set along the shoreline and in shallow offshore locations that encompassed multiple habitat types. Bluegill comprised a majority of the trap net catch by number and biomass. The number of Bluegill sampled per net was above the 50% quartile for similar Lake Class 23 lakes and the average length was 5.2 inches, with 23% over 7 inches. The nearshore and trap net data were combined with gill net data from a June 2020 survey to describe the fish community and provide a Fish-based IBI (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., Blackchin Shiner, and Iowa Darter), while other species are tolerant of degraded conditions (e.g., Green Sunfish). 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 indicates Big Too Much Lake is in good health as indicated by an FIBI score well above the impairment threshold and exceptional thresholds for aquatic life use determined for similar lakes. Data from this survey will contribute biological information about the health of the fish community to the Big Fork River Watershed assessment process in coordination with MN Pollution Control Agency.
