The Williamson River and crystal-clear Spring Creek meet in the park. The Williamson River is regionally famous for its quality trout fishery and consistently produces trophy fish. Spring Creek gushes dramatically out of a nearby spring and then paints a picture-perfect scene at it flows through the park.

Jackson F. Kimball State Recreation Site
J. F. Kimball State Park is a pristine site located at the headwaters of the Wood River. This stream flows from the pine forest into open meadow land laced with picturesque aspen surrounded by the southern Cascade Mountains. Wood River offers fine fishing that can be accessed from the park by canoe. Kimball Park offers primitive camping next to a spring-fed lagoon at the beginning of this waterway.
