South Teal Lake is located within the Columbia National Wildlife Refuge (CNWR) south of Potholes Reservoir. WDFW fishing regulations and licenses apply to all lakes within this federal refuge. Vehicle or walk-in access to these lakes is managed by the USFWS. WDFW recommends that anglers review access and other regulations on the CNWR website (http://www.fws.gov/columbia/).
South Teal Lake was rehabiliated in 2010 to eradicate nuisance fish species and restore the trout fishery. Since the rehabilitation, fishing at South Teal Lake has mostly been good for Rainbow Trout ranging in size from 12-20 inches. Fish is best from boat, but shoreline fishing can also be effective.
