Although Perch Lake is one of the principal features of the golf course, Memorial Park, and Fisherman's Park, it also is a unique feature in its own right. It has 32 surface acres with a maximum depth of ten feet and a mean depth of five feet. It was created by damming the La Crosse River. Most of the land around the lake is City owned except for one private home and a VFW clubhouse. The lake has a native fishery of warm water pan fish, largemouth bass, northern pike, and some brown and rainbow trout, all of which is supplemented by stocking as recommended by fishery management professionals. The Lake was last dredged in 2000.
