Rimrock Lake

This large Tieton River impoundment stretches along Highway US-12, about 10 miles east of White Pass. It is in the Wenatchee National Forest at 2,922 feet elevation (at the spillway).  It is open to fishing year-round.  Rimrock provides good fishing for eight- to 11-inch kokanee; with a generous kokanee catch limit of 10 fishRainbows are also available, some up to 16 inches.  This is normally one of the best and most popular kokanee-fishing destinations in Yakima County from early May through August.  Trolling and still fishing is effective and chumming is permitted.   There is a 5 trout daily limit (excluding kokanee) with no minimum size requirement.      

The lake is closed to fishing for bull trout.  Please carefully release any bull trout that are inadvertantly hooked.   

Public and private campgrounds are located by the lake and public and private launch ramps are available. The Forest Service charges a boat launch fee at their locations.
