6,800-acre reservoir near Moses Lake. The lake tops out around 36 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 6,531 acres wrapped in 67.1 miles of bank, with 7 islands in the mix. That shoreline is heavily fingered (development index 5.9) — bays, points and pockets everywhere, which multiplies the fishable edge. About 76% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 13.3 mi, about 5.4 mi across. It sits in Grant County. If the bite dies, Potholes Reservoir is 10 mi to the south.
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 15 to 35 ft before dropping to 11 to 36 ft for winter. The spot to know is Sharp break, a drop-off in about 26 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
