Brook Trout fishing at Ross 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. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores good in spring. Best bite is early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.

|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Cisco (Lake Herring) fishing at Ross Lake
Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. By summer they slide out to 40 to 80 ft, and by winter most fish are in 20 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 76 ft that scores prime in summer. In summer the feeding windows fall in early morning.
