• Where to Fish on Divide Reservoir

  Depth went unrecorded, which puts the reading back on you. The arms fish better than the open middle whenever the water is up. Inflow corners move water, and moving water gathers fish. County-wide records name black-spotted cutthroat trout, brook trout, brown trout and bluegill. What holds for the county may not hold for this water. Divide Reservoir responds to conditions more than to tactics.

• Seasonal Patterns

  Temperature averages peak at 72°F in July and bottom out at 28°F in January. Fishing continues through most of the calendar, with quiet spells rather than closures. It is not guaranteed from one year to the next. February into May fishes hardest as the water warms. Divide Reservoir runs to its own calendar within the local pattern.

• Tackle & Baits

  Our records carry no access rule either way. No made access is recorded, so a short walk in is the likely arrangement. For the trout, small spinners and a box of nymphs cover both approaches. Where the road in crosses private land, ask first. Some stretches are reserved and marked as such on the ground. Walker Reservoir sits 0.8 miles off and takes the overflow. For Divide Reservoir in particular, ask before you travel.
