Rock Lake

One mile north of Ewan. This is the largest natural lake in eastern Washington. With a year-round open fishing season, this mixed species fishery has a reputation of providing an excellent fishery for Rainbow and Brown Trout. Largemouth bass, Bluegill and Crappie are also available from this lake.

The boat launch is privately owned but maintained by WDFW which allows for public access.  The access is a rough boat ramp; launch your vessel with caution, and please clean up after yourselves.

Two-pole fishing is allowed

Shoreline access: Good
Although the most anglers fish this large lake from boats, shoreline fishing access is available near the boat launch area.
