Here’s a lake survey from 2003.

Status of the Fishery (as of 06/30/2003)
Horseshoe Lake is located northeast of Waterville on the Rice – Le Sueur County boarder. Horseshoe Lake had low oxygen conditions in the winter of 2000 to 2001 that resulted in some winterkill of fish. A fishery survey was conducted in 2003 to monitor the fish community and habitat in Horseshoe Lake. Northern pike are abundant in Horseshoe Lake and should provide excellent angling. Most were around 20 to 30 inches in length. Some walleye are present and were around 13 inches in length. Black crappie, bluegill, and yellow perch are present in moderate numbers. Panfish populations are recovering from the winterkill and may provide increasing angling opportunities in the next few years. Black bullhead are abundant, although most fish were around only 4 to 5 inches long.

Do note that bass were not shown in any of the test nets so if you’re a bass guy this lake definitely isn’t for you. The pike fishing sounds like it might be pretty good for numbers.
