No WDFW calendar for Brown Trout — the lake holds it, WDFW just doesn't rate its months.
WDFW rates rainbow trout best in April through June.
WDFW draws one calendar per species for the whole state, so it shows the season's shape rather than this lake's own record. Check the rules for when each species is open here. This lake on WDFW
