15-acre lake near Seattle. The lake tops out around 31 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. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Bitter Lake draws 15 acres inside 0.7 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. About 44% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.3 mi of water from one end to the other. The water lies in King County. Closest neighbour on DepthScout: Green Lake, 3 mi south of here.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 6 to 31 ft for winter. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 23 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
