History & Status of the Fishery
Long Tom Lake is a 133-acre reservoir located three miles east and two miles north of Ortonville in Big Stone County. The lake is primarily managed for walleyes. A fishing pier and boat launch are located on the north side of the lake. A winterkill occurred during the winter of 2018-2019 even though an aeration system was being used. Poor success with aeration had also occurred during previous winters and therefore it was discontinued as a management tool at Long Tom Lake.
Low water, drought, early ice and a thick snowpack resulted in low oxygen and winterkill in Long Tom Lake during the winter of 2022-2023. Almost no measurable oxygen was present by mid February of 2023. Thousands of dead fish were observed during ice-out. Walleye fry were stocked during spring and black crappie and yellow perch will be stocked when available.
This standard survey revealed that although the winterkill was severe, it wasn't complete. Standard sampling using a gill net and trap nets captured black bullheads and common carp during spring. Small mesh trap nets were used to assess natural reproduction in late summer. The catch primarily consisted of fathead minnows, black bullheads and common carp, however two young-of-year walleyes were also caught. The fishery will require some time to recover from the winterkill and good fishing will likely be at least two years into the future.
