Lake Overview:

Banks Lake (27,000 acres): Stretching almost 27 miles from Coulee City in the south to Grand Coulee in the north, this large reservoir is popular with anglers pursuing many species. Smallmouth bass up to 4 pounds are plentiful along rocky shoreline areas, and largemouth bass fairly abundant in the northern part and weedy bays. Effective May 1, 2006, the daily limit for smallmouth bass here increases to 10 fish, with no more than 1 over 14 inches; rules for largemouth bass are unchanged from the standard statewide slot limit. Walleye fishing is still very good. A cooperative rearing project between WDFW, an Electric City sportsmen’s group, and Coulee City Chamber of Commerce offers improved fishing for rainbow trout up to 5 pounds. Approximately 1 million kokanee have been stocked annually in recent years, some of which the net pens also help raise. Angling for kokanee up to 19 inches has been variable during mid to late summer. Chumming is permitted. Yellow perch and crappie angling is good, but bluegill fishing will be poor-to-fair. There is a 25-fish daily limit on perch to prevent over harvest of this important forage and sport fish species. Lake whitefish are a very abundant and overlooked game fish. Several public access areas are well developed, including a Steamboat Rock State Park about mid-way up the lake, a city park at Coulee City on the south end, and several resorts at the north end.

Banks Lake is located between Coulee City and Electric City along Highway 17. Banks Lake is an irrigation impoundment, has a surface area of 26,887 acres, and a mean depth of 46 ft. Banks Lake was once known as the state’s premier walleye fishery; however, recently smallmouth bass have become a much more abundant and popular gamefish in this lake. Anglers will also find excellent perch fishing along the jetties on the south end, near the north end west of Steamboat Rock, and seasonally in the shallow bays of the northeast side of the reservoir. Other gamefish found in Banks Lake include crappie, bluegill, bullheads and channel catfish. Deepwater fish species found in Banks Lake include burbot (also known as freshwater ling) and lake whitefish. Rainbow trout and kokanee are stocked annually. Banks Lake has a dedicated research team that is investigating limiting factors associated with the Banks Lake fishery. Banks Lake is also surveyed each fall using gill nets to determine walleye abundance. Source: WDFW 2007-08 Region 2 Warmwater Fishing Opportunities

Banks Lake, part of the Columbia Basin Project, was created by building two rock-faced, earthfill dams at the north and south ends of the Ice-Age channel of the Columbia River, now known as Grand Coulee. The reservoir is 27 miles long with 27,000 water surface acres. Fishing opportunities for smallmouth bass, largemouth bass, yellow perch, rainbow trout, walleye, kokanee, black crappie, bullhead, and whitefish. Developed camping facilities are also available.
