Rend Lake consists of 18,900 acres of water and 20,000 acres of land. Surrounded by hills, prairies and bottomlands, the scenery at the lake never disappoints.


Rend Lake is a relatively shallow reservoir, filled with countless native species of fish, making it an ideal angling destination. Abundant and large crappie and channel catfish are especially popular, along with hybrid striped bass and flathead catfish.

Birding is a popular pastime at the park, and the area provides the ideal habitat for a diverse range of bird species.

The lake has earned the reputation of being one of the best waterfowl hunting areas in the state for both ducks and geese.
