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, 2020
Manuel Mine Pit Lake is a former open pit iron mine that has filled with water and is managed as a designated stream trout lake for Rainbow Trout. The dissolved oxygen and temperature profiles were measured on August 12, 2020 to monitor habitat for trout. Optimal thermal and oxygen conditions for Rainbow Trout (11-19° C [52-66° F] and greater than or equal to 5 ppm DO) occurred in about 8 vertical ft from a depth of 24 to 31 ft. At the maximum depth measured, 49 ft, the temperature was 6° C (42° F) with 10.1 ppm dissolved oxygen. The coldwater habitat index value of the temperature at a dissolved oxygen concentration of 3 ppm (TDO3) value was likely several degrees less than the 6° C minimum temperature measured. Manuel is normally stocked with about 3,000 yearling Rainbow Trout each spring with additional surplus yearling or adult Rainbow Trout occasionally stocked in the fall, winter, or spring when available. Manuel is located in the Cuyuna Country State Recreation Area. Consult State Recreation Area regulations for vehicle permit and other use information. Designated stream trout lakes have additional angling regulations. Be sure to consult the current Minnesota Fishing Regulations book for regulations, seasons, and possession limits before fishing designated trout waters.
