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.

DNR fish survey, 2018
Weasel (formerly Sled) is a designated stream trout lake, stocked with Rainbow Trout in the years preceding this survey. Because that stocking seemed to have failed, the latest (2018) lake management plan called for a return to Brook Trout stocking, beginning in 2020. This survey was done to provide a final assessment of Rainbow Trout stocking success. Rainbow Trout stocked in 2013, 2015, and 2017 should have been present and vulnerable to the gears used in this surveys. No fish were taken in any of the gill net sets used in this survey. Rainbow Trout gill net catches in this lake have been low in the past (zero to one fish per survey), so it was not surprising that none were taken in this survey. Survey results help confirm the choice to abandon Rainbow Trout stocking in this lake. Weasel is typical of many small, bog-stained lakes in the area, with surface waters that at times may be quite warm, with dissolved oxygen levels dropping quickly at a shallow depth, and with colder, deeper waters largely devoid of oxygen. In this survey surface temperatures had already reached levels stressful for Brook Trout by 21 June. Conditions that would have been optimal for Brook Trout (water temperature 5 ppm) still existed, at depths of about four to seven feet; however, those conditons likely deteriorated as the summer progressed.
