Better dust off the tackle box as trout fishing is just around the corner. In addition to the lakes that I have mentioned that will be opening to trout fishing on March 1st, there are many other lakes in Eastern Washington that share that opening date. In Columbia County, the five Tucannon River off-channel lakes — Blue, Deer, Rainbow, Spring, and Watson — open March 1. These lakes are stocked with rainbow trout weighing up to 1.5 pounds. In Spokane County, Liberty Lake opens March 1 and received 4,000 catchable-size rainbow trout and 350 jumbo rainbow trout in 2026. Trout at Liberty Lake can range from 12 to 16 inches. Amber and Medical lakes also open March 1; both lakes are managed under selective gear rules and are expected to fish well this spring. In Lincoln County, Coffeepot Lake opens March 1 and is scheduled to receive 5,000 put-grow-take rainbow trout in spring 2026. In Whitman County, Pampa Pond opens March 1 for rainbow trout fishing. In South Central Washington, many lakes in Benton, Franklin, Kittitas, and Yakima counties are open year-round, and WDFW typically begins stocking catchable trout during the first week of March.
