Brook Trout fishing at Topsy Lake
In spring, brook trout run shallow here, mostly 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 18 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months.
