Fishing Blue Mountain Reservoir in Larimer County, Colorado

• Overview

  Blue Mountain Reservoir is one of the Larimer County waters in Colorado. Country round the bank runs to mixed woodland. Roughly 37 acres: a morning covers one end, an afternoon the other. The nearest place of any size is Berthoud, 4.7 miles away. It is 19 miles to Boulder, the nearest city. The boundary is near enough that local access rules are worth double-checking.

• Where to Fish on Blue Mountain Reservoir

  We hold no survey for this water; read the slope of the shoreline instead. Look for where the old bank line still shows under the surface. Inflow corners move water, and moving water gathers fish. Records held for Larimer County cover black-spotted cutthroat trout, brook trout, white sucker and rainbow trout. Species recorded across the county may be limited to a few waters. Take Blue Mountain Reservoir a stretch at a time.

• Seasonal Patterns

  Averages move between 28°F in January and 72°F in July. In milder years the surface never sets. It should never be assumed safe, whatever the month says. June to September is hot work, so the first and last hours are what count. Plan around that when you fish Blue Mountain Reservoir.

• Tackle & Baits

  The access position is unclear from public sources. Fishing from a pier is possible half a mile away. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Read any posted signs at the access point rather than assuming. Where tickets apply, they are sold in the nearest town rather than on the bank. Highland Reservoir Number 2 at 1.2 miles is the sensible second choice. Confirm before you fish Blue Mountain Reservoir.
