Trapper’s Bay State Park
Iowa Great Lakes Historic Picnic Park — 1933 CCC Stone Shelter on National Register, Silver Lake Walleye and Pike Fishing, Boat Launch, Dickinson County
Trapper’s Bay State Park is a state park at 309 Trapper’s Bay Road, Lake Park, Dickinson County, Iowa, on the north shore of Silver Lake in the Iowa Great Lakes region. The park features a historic 1933–1934 Civilian Conservation Corps (CCC) picnic shelter listed on the National Register of Historic Places, boating and fishing access to Silver Lake’s walleye, northern pike, yellow perch, and largemouth bass, a boat launch, and a quiet, intimate setting on the Iowa Great Lakes.
Trapper’s Bay preserves one of Iowa’s finest CCC-era structures — the 1933–1934 picnic shelter is built in “Rustic” architectural style with random rubble stone walls on the back and sides, blending seamlessly into the natural lakeside setting. Listed on the National Register of Historic Places (NRHP #90001676, November 15, 1990), the shelter represents the craftsmanship of Depression-era conservation workers who built Iowa’s state park infrastructure.
The park sits on Silver Lake — smaller and quieter than the nearby Iowa Great Lakes giants (Spirit Lake, West Okoboji). This makes Trapper’s Bay a peaceful alternative for fishing and picnicking without the weekend crowds that pack the more famous lakes. The north shore location provides wind-sheltered fishing access during prevailing south winds.

Historic Significance
The Civilian Conservation Corps (CCC) operated from 1933 to 1942 as one of President Franklin D. Roosevelt’s New Deal programs. Young men enrolled in the CCC built roads, trails, shelters, and park infrastructure across the nation during the Great Depression. Iowa’s state parks contain some of the finest surviving CCC structures in the Midwest, and the Trapper’s Bay shelter is among the best-preserved examples.
