• Where to Fish on Sullivan Reservoir

  No published figure covers depth, so learn it as you fish. Standing timber shows when the level drops, and fish sit against it. Draw-down through summer strips the margins, so follow the water out. Reported across Routt County: brook trout, cutthroat trout, rainbow trout, mountain whitefish and mountain sucker. Those are county-wide records, so not every one of them will be in this water. On Sullivan Reservoir that means starting tight and working out.

• Seasonal Patterns

  In an average year July sits at 62°F and January at 21°F. The season turns properly here, and fish follow it closely. Count the season from break-up, usually mid April. Ice clears near mid April and comes back about late November in a typical year. Look to early summer and the first cool weeks of autumn. The season on Sullivan Reservoir rarely departs from it.

• Tackle & Baits

  Nothing in our records says who may fish here. Nothing built is recorded close to the bank here. For the trout, small spinners and a box of nymphs cover both approaches. Where the road in crosses private land, ask first. A polite question at the farm gate opens more banks than anything else. Should this one be busy, Sagebrush Reservoir Number 1 is 3.2 miles off.
