The Poweshiek County Conservation Board operates Diamond Lake County Park within the broader Diamond Lake Wildlife Area, managing 120 campsites across 90 acres of lake frontage and 660 acres of prairie. This first-come, first-served campground divides into two distinct sections: 80 RV sites with electric and water hookups clustered together, and 40 primitive tent sites positioned directly along the water's edge.
Multiple reviewers highlight the campground's organization, with RV areas featuring concrete pads and newer hookups while tent campers access lakefront spots just steps from the water. Stuart K. notes the primitive sites offer "front-row access to lakeside camping bliss" despite lacking electricity. Sites sit close together, which several campers mention creates crowded conditions during peak times, though mid-October visits tend to be quieter.
Diamond Lake's 90 acres provide kayaking and fishing opportunities, with anglers reporting bluegill and crappie catches. The murky water conditions limit swimming appeal, but multiple boat launches and a fishing dock accommodate watercraft access. Three shower houses serve the campground, with reviewers consistently noting clean facilities. A playground, fish cleaning station, and four shelters round out the amenities.
Highway 85 runs nearby, creating some road noise that campers can hear from their sites. The campground sits 20 minutes south of Interstate 80 via Road 63, making it accessible for travelers seeking an overnight stop. Self-registration operates on-site with electric sites at $20 nightly and primitive spots at $10. For additional camping options in the region, visitors can explore campgrounds around Montezuma. Fall colors peak in mid-October when occupancy drops significantly, offering more solitude for late-season campers.
