Wakesurfing on Banks Lake

Banks Lake rates Excellent for wakesurf suitability. Deep and roomy enough to ride the way the sport’s own guidance recommends. The rating is based on its measured surface area of 26,886 acres. This is a read of the water's dimensions, not legal permission — check the Washington rules and the local authority for this lake before you launch.

No maximum-depth measurement is on record for Banks Lake in the state agency data we use, so its depth factor is unrated. We do not estimate depth.

Banks Lake carries a LakeQuality water-quality grade of A, computed from EPA and state monitoring data — Secchi clarity, total phosphorus, and chlorophyll-a. That is a separate question from wakesurf suitability: a lake can be excellent to ride and mediocre to swim in, or the reverse. See the full lake page for the grade breakdown.

Washington has no statewide wakesurfing-specific law. Statewide rules require reducing to no-wake speed when approaching a person on a surfboard or others in the water and bar towed watersports one hour before sunrise to one hour after sunset, but wake-surf setbacks are addressed locally (e.g., advocacy and proposed restrictions on Lake Sammamish). Local variation in boating rules is authorized by waterbody. Individual lakes often add stricter local limits on top of the statewide rule — no-wake zones, operating hours, and horsepower caps are all common — so confirm with the local authority for Banks Lake.
