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 Roemhildts Lake was conducted on July 12, 2022, by DNR Fisheries staff. Ten 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 6 sampling stations, but 3 stations were sampled from the boat due to site conditions. Similarly, a 50-foot seine was used to sample 4 stations, a 15-foot seine was used at 3 stations, and site conditions prevented the use of seines at 3 stations. Nearshore sampling captured 10 species of fish including 2 species that are intolerant of disturbance (Banded Killifish and Iowa Darter) and 1 species that is tolerant of disturbance (Green Sunfish). The nearshore data were combined with trap net and gill net data from a standard 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., Banded Killifish), 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 Roemhildts Lake is in good health as indicated by an FIBI score above the impairment threshold 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 Cannon River Watershed assessment process in coordination with MN Pollution Control Agency. Minnesota DNR Fisheries Area staff conducted an assessment of lakeshore habitat on Roemhildts Lake on Aug 01 2022, following the Score the Shore survey protocols. The assessment consisted of 21 survey sites evenly spaced 100 meters around the lake. The average lakewide habitat score was 83.3 (+/- 2.9), indicating overall lakeshore habitat quality was moderate (66-84). Approximately 42 percent of the sites were developed with a mean score of 73.5 (+/- 4.6), while undeveloped sites had a mean score of 90.6 (+/- 1.7).
