State Park is located near Garrison Dam on the lake's southern shores and Pick City
The park is a favorite among visitors and offers a full range of amenities including a full service marina, including boat rentals, convenience store, fishing guide services and boat and camper storage. Two large boat ramps serve the park for access to the lake.
Salmon fishing is especially good at this end of the lake. As a testiment, the park sponsors several fishing derbies throughout the year.
