Fishing Nahwatzel Lake: what the data says
272-acre lake near Mason County. The lake tops out around 25 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.
Cutthroat Trout fishing at Nahwatzel Lake
In spring, cutthroat trout run shallow here, mostly 3 to 15 ft. Summer pushes them deeper, 7 to 25 ft, and winter fish settle into 6 to 25 ft. If you only fish one area, make it Outlet Creek inflow: a inflow / creek mouth around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Summer baits: a trolled spoon (small) or a inline spinner gets it done.
