Jackson F. Kimball State Recreation Site, State recreation site in Klamath County, Oregon, US.

Jackson F. Kimball State Recreation Site is a 19-acre park at 4,211 feet in the Cascade Mountains, where a spring forms the headwaters of the Wood River. The site holds a spring-fed lagoon and is forested with ponderosa and lodgepole pine and some quaking aspen. A short trail links the ten primitive campsites to the spring.

The site was created in 1955 when the Oregon Board of Forestry transferred land to honor forest warden Jackson F. Kimball. This action preserved access to the spring and surrounding forest for public use in a strategic mountain location.

The spring represents a focal point where visitors can observe how water shapes the local landscape and supports the recreation activities around it. Local communities value this site for its role in sustaining both wildlife and outdoor traditions in the region.

The park has ten primitive campsites near the headwaters lagoon; toilets are primitive and no potable water is available, so bring your own. A short trail links the campground to the spring where the Wood River begins. The horse trail from Collier Memorial State Park leads through forest to the site. The park usually opens mid-April and closes in October, though deep snow can delay opening until June.

The spring water arrives here after traveling underground from higher elevations in the mountain range above. Few visitors realize the water has journeyed beneath the surface before emerging into the visible lagoon and river.
