No WDFW calendar for Brook Trout, Brown Trout or Tiger Trout — the lake holds them, WDFW just doesn't rate their months.
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
