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 Marshall Lake was conducted June 27th and 30th, 2025, by Detroit Lakes Fisheries Staff. Data was collected from 9 sampling stations spaced around the lake. All stations were sampled with a backpack electrofishing unit, four were sampled with a 50-foot seine and five stations were sampled with a 15-foot seine. Nearshore sampling captured 10 species of native fish, which included two species that are intolerant of disturbance (Blacknose Shiner and Iowa Darter) and two species that are tolerant of disturbance (Black Bullhead and Green Sunfish). The three most common species captured during the nearshore survey in order of abundance were Spottail Shiner, Bluegill, and Green Sunfish. The nearshore fish survey data was combined with the standard survey data from June 2025 to describe the fish community and provide a Fish-based Index of Biotic 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., Blackchin Shiner, Iowa Darter, and Rock Bass), while other species are tolerant of degraded conditions (e.g., Black Bullhead, Fathead Minnow, and 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 will contribute biological information about the health of the fish community to a watershed assessment process in coordination with MN Pollution Control Agency. Marshall Lake is located in the Buffalo River Watershed.
