• Where to Fish on Green Lake Number 1

  Depth went unrecorded, which puts the reading back on you. Inflow corners move water, and moving water gathers fish. Draw-down through summer strips the margins, so follow the water out. Fish documented in Boulder County include black-spotted cutthroat trout, brook trout, brown trout, bluegill and rainbow trout. The county figures include rivers and lakes alike. Treat this water as a water to read rather than to cover.

• Seasonal Patterns

  The year swings from about 17°F in January to roughly 50°F in July. The freeze arrives properly here and holds. After late May the shallows warm and the fish move up. The season between ice runs from about late May to early November. Fishing peaks soon after break-up and again before the cold returns. That shapes the year on this water.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. Access points are not mapped for this water, which suits people who like quiet. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Rules differ from one water to the next round here. Rules for boats are stricter than rules for the bank in many places. Green Lake Number 2, 0.3 miles away, makes the obvious fallback. What applies at this water may have changed since it was mapped.
