Big Creek State Park

Big Creek Lake was created as part of Saylorville project to protect Polk City from the floods. A diversion dam which forms the 866-acre Big Creek lake protects Polk City from Big Creek floods, and a barrier dam protects the city from flood waters from Saylorville Lake. Saylorville was primarily a flood control project but also offers a wide variety of recreation. Big Creek State Park and the adjoining public hunting areas provide recreation for visitors of all ages and interests. The focal point of the 3;550-acre complex is the lake.

Big Creek offers a wide variety of recreational opportunities with picnic areas, a swimming beach, a playground, a marina with canoe, paddle boat, catamaran sailboats, and other rentals, and a shooting range. Please visit the Iowa DNR website for additional information at:
