Spring Lake State Park, run locally as Spring Lake Park, is an Iowa state park near Jefferson in Greene County, managed by the Greene County Conservation Board. Its 240 acres include a 50-acre lake whose shoreline sits nearly level with the water, so many campsites line the edge of the lake.
Who Runs Spring Lake
The Iowa DNR lists Spring Lake among the “state parks managed by other entities” in its 2026 state park guide, with the Greene County Conservation Board as operator. For questions, call the board at (515) 386-5674.
Camping at Spring Lake
The park has 120 electrical campsites for tents and RVs and two shower houses. Reservations go through Spring Lake Park’s page on mycountyparks.com, the booking link given in the park’s description on Experience Jefferson (as of October 2026). Iowa’s state park reservation system does not cover Spring Lake. Nightly rates are not published on the pages we could read, so check them on the booking page.
On the Water
The Iowa DNR measured the lake at 51 surface acres with a maximum depth of 6.8 feet (2014), and only electric motors are allowed. The DNR manages it for a high-density channel catfish population and stocks advanced fingerling catfish at a higher rate than typical lakes (fishing summary last updated August 2019). Bluegill, common carp and largemouth bass round out the popular species.
A concessionaire rents paddleboats, kayaks and canoes and sells food and drinks, and there is a designated swimming beach.
More to Do
An 18-hole disc golf course winds through the park, and the concessionaire also runs roller skating. About 120 of the park’s acres are wooded, with deer, turkeys, small mammals and many birds, and several hiking trails cross the woods. More than 2 miles of paved park roads work well for biking, jogging and walking.
Getting There
The park is on 195th St. off County Road P33 and Highway 30; Travel Iowa lists the address as 1847 195th St, Jefferson, Iowa. The DNR’s county park list places it 5 miles northwest of Grand Junction.
