| 2024 | Walleye | fry | 165,000 | 1.3 |

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 Emily Lake was conducted on July 15th 2024, 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 10 sampling stations. Similarly, a 50-foot seine was used to sample four stations, and a 15-foot seine was used at four stations. Two stations were not seined due to mucky substrate and dense vegetation. Nearshore sampling captured 8 species of fish including one species that is intolerant of disturbance (i.e., Iowa Darter) and two that are tolerant of disturbance (i.e., Common Carp and Green Sunfish). A concurrent summer trap net survey was also conducted by IBI Program staff. Nine trap nets were set along the shoreline in locations that encompassed multiple habitat types. Trap net sampling captured nine species of fish, two of which are considered tolerant of disturbance. Bluegill comprised a majority of the catch by number, whereas Bigmouth Buffalo comprised a majority by biomass. The nearshore and trap net data were combined with gill net data from a June 2023 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., Iowa Darter, and Rock Bass), while other species are tolerant of degraded conditions (e.g., Green Sunfish and Common Carp). 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. Results from this survey provide evidence that the fish community in Emily Lake may be adversely impacted by stressors as score is near impairment threshold for aquatic life use determined for similar lakes. The survey results will be considered when the biological health of the lake is assessed during the Minnesota River - Mankato watershed assessment process, which will be completed in coordination with MN Pollution Control Agency. You can help protect the fish community in Emily Lake by reducing runoff, maintaining natural shorelines, and preventing the spread of invasive…
