Iowa’s Tuttle Lake Picnic Park — Walleye & Northern Pike Fishing, CCC-Era Stone Bathhouse Ruins, Lakeside Shelters & Des Moines River Access in Emmet County
Okamanpedan State Park is a small, passive-use lakeside park on the shores of Tuttle Lake in Emmet County, Iowa, near Dolliver. The park offers shoreline fishing access for walleye, northern pike, smallmouth bass, white bass, and panfish, river fishing on the East Fork of the Des Moines River, a historic CCC-era stone bathhouse structure, a shady lakeside picnic area, an open shelter, and walking trails.
While Okamanpedan is a smaller, quieter state park without a campground, its fishing access on Tuttle Lake is the primary draw. The lake produces walleye, northern pike, and bass — species not always common in smaller Iowa lakes. The park preserves a Civilian Conservation Corps (CCC)-era stone bathhouse, a remnant of the 1930s New Deal park-building program. A boat ramp adjacent to the park provides lake access. For camping, the nearby Tuttle Lake Recreation Area on the southwest shore offers developed campsites.
