Deep Lake (Grant County)

Deep Lake is located north of Soap Lake and east of Park Lake.  This lake is a popular opening day lake and in most years produces good angler catch rates.  Deep Lake is also stocked with Kokanee that range in size from 10-13 inches.  Kokanee are an underutilized resource at Deep Lake.  This lake is best fished from a boat, but shoreline fishing at times can be productive.


Two-pole fishing is allowed

Shoreline access: Good - There is some shoreline fishing at the boat ramp and along the southern area of the lake.

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.

The Kokanee fishery typically lasts from April-October before the adults leave the lake to spawn in tributaries starting in late-October and early-November. Fishing is best in the spring before they move into deeper water to avoid warming water temperatures, but they can be targeted throughout the summer in deeper offshore areas near the thermocline. There may be a slight uptick in some waters in the fall as adults return to shallower water and move near shore towards spawning tributaries.
