Brook Trout fishing at Grant Lake
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Deep basin, a deep basin in about 30 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
