109-acre lake near Mason County. The lake tops out around 30 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. What follows comes from the same scoring engine that paints the spots above.
On the chart, Haven Lake draws 109 acres inside 1.7 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 44% of the water is 15 ft or less, the band where the food chain lives. Figure 0.6 mi of water from one end to the other, 0.5 mi at the beam. You'll find it in Mason County. Closest neighbour on DepthScout: Lake Wooten, 1 mi north of here.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 6 to 30 ft. Creek inflow is the standout, an inflow / creek mouth at roughly 27 ft, rated prime for summer rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
