Lake Joanis is a 24-acre lake and island in the southeast corner of Schmeeckle Reserve. Its maximum depth is 27 feet. 

Buffered from the surrounding city by natural vegetation, few people realize that the lake is manmade.  In 1975, Sentry Insurance needed fill for the construction of its new world headquarters. Partnering with the UW-Stevens Point Foundation, Sentry excavated the lake to obtain fill and create a natural focal point for campus. This development led to the creation of Schmeeckle Reserve.

Today, the lake harbors a variety of plants and animals, serves as an important resting area for migrating waterfowl, and provides recreational opportunities for the campus and community.
