Welcome to Poweshiek County Conservation

The campground at Diamond Lake remains open through the winter! Though we’ve closed and winterized our bathrooms, most of our campsites still have water and electricity (we’ve bagged the hydrants at the sites where the water is off) and our dump stations are open.

Diamond Lake Campground operates on a first-come first-served basis, and has self-registration stations at each entrance so you can check in at any time! Please register as soon as you claim your spot, and fill out ALL fields on the registration envelope! Thank you!

We also close the north road to vehicles this time of year, but hiking is still allowed on the northwest side of the lake. You can park in front of the ranger house or at the Foster Center to access the trails – be aware that public hunting ground is directly adjacent to the park in some places – so keep an eye out for signs that show the park boundaries.

The purposes of the Poweshiek County Conservation Board, as established by law, are: “To acquire, develop, maintain, and make available to the inhabitants of the county, public grounds, recreational center, county areas, and to promote and preserve the health and general welfare of the people, to encourage the orderly development and conservation of natural resources, and to cultivate good citizenship by providing adequate programs of public recreation.”

The Conservation Board administers 9 park and wildlife areas that encompass over 2,173 acres of land dedicated to public use and enjoyment.  Our parks and wildlife areas are managed for you, so please remember to leave them as you would like to find them.
