Brook Trout fishing at Irrigation Lake
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores good in spring. In summer the feeding windows fall in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
