Williams Lake

Fourteen miles north of Colville this lake has an elevation of 1950 feet. The fishing season is open from the first Friday after Thanksgiving through March 31. This "winter-only" lake normally produces rainbow trout in the 10- to 13-inch range, with carryovers in excess of 14 inches.

Williams Lake is highly productive and an aerator must be operated during winter months (November - March) to prevent winter-kill.  An open-water area is maintained by the aerator in the center of the lake during periods of ice cover.  Anglers should stay well away from the thin ice and open water at all times.  In rare instances when the aerator malfunctions (power outages, mechanical failure), a thin layer of ice quickly forms over the open-water area.  This thin layer of ice cannot support human weight, and snow cover can make it difficult to tell accurately where the ice is thin.  Therefore, anglers should avoid the center of the lake at all times.  Although every effort is made to regularly check and maintain the aerator, breakdowns occasionally occur.  WDFW requests that anglers call 509-563-5490 if the Williams Lake aerator is not functioning during winter.

Two-pole fishing is allowed

Good for ice fishing

Shoreline access: Good - Due to winter-only season, lake is usually ice-covered, so walk-in access is good.

Fishing prospects calendar

Rainbow trout

Fishing success for Rainbow Trout is generally best in the spring when thousands of fish are stocked statewide, but they can be caught year-round in most waters with a little patience and persistence. Success remains high into June and gradually declines as water temperatures increase and fish move offshore to stay cool. Fish that escaped the spring harvest return to the nearshore areas in the fall as waters cool off. Some waters may also be stocked again in the fall further boosting catch rates.

Largemouth bass

Fishing improves throughout the spring as waters warm and fish move onshore, peaking during the spawn. Summer is a slight lull though dawn/dusk hours can be very good. Catch improves in Fall as waters cool, vegetation begins to die back, and prey becomes more available. Winter is the hardest time because fish are offshore and slow moving.

Yellow perch

Yellow Perch can be caught year-round. Fishing is best in the summer after they finish spawning in April-May. Fish can be readily angled through the summer from both the shore and boat. Catch begins to decline in the fall as water temperatures cool and fish move offshore forcing anglers to pursue them in boats. Successful fishing for Yellow Perch in the winter involves either targeting schools in deep water from boats or through the ice.
