Pearrygin Lake is a 212-acre (86 ha) reservoir lying 1.5 miles (2.4 km) northeast of Winthrop in Okanogan County, Washington. It has a maximum depth of 49 feet (15 m) and a water volume of 6,260 acre-feet (7,720,000 m3). The lake is fed by a diversion from the Chewuch River and several small inlets; it drains westerly into the Chewuch River. It lies within the watershed of the Lower Chewuch River.
The lake is oriented from northwest to southeast in a narrow, glacially carved valley where it abuts a forested slope to the south and open shrub-steppe habitat to the north. It is located in Section 36, Township 35N, Range 21E. The lake is almost entirely surrounded by Pearrygin Lake State Park. A privately-owned RV camping resort occupies the lake's northern shore. The lake's primary sports fish is rainbow trout.
