Triangle Lake Fishing Guide, Boulder County, Colorado

• Overview

  Boulder County in Colorado is where Triangle Lake sits. Around the bank it is rolling bush. About 4 acres of surface, which puts the far bank inside easy sight. Most waters listed here for Boulder County are larger. The closest town, Nederland, is 11 miles away. Boulder is the closest city, 21 miles away. There is no boundary nearby to worry about.

• Where to Fish on Triangle Lake

  Depth is unmeasured here, so let the shoreline guide you. Bays and points beat straight shoreline every time on water like this. The shallow end warms first and pulls fish in ahead of the rest. Open biodiversity records for Boulder County list black-spotted cutthroat trout, brook trout, brown trout, bluegill and rainbow trout. County records show the wider picture rather than this one place. Triangle Lake repays a walk before the first cast.

• Seasonal Patterns

  Between January at about 17°F and July at about 50°F, the water has a wide range to work through. A full turn of seasons, with the strongest sport on either side of summer. Ice is part of the season here, ending near late May. The season between ice runs from about late May to early November. May into June fishes hardest, and September gives a second good stretch before the lid returns. On Triangle Lake that shapes the whole year.

• Tackle & Baits

  Nothing on record says whether the bank is open or closed. Nothing is listed nearby for parking or launching a boat. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Take the rules with you rather than trusting memory. Signs go up and come down, so check on the day. Crater Lake, 0.8 miles away, makes the obvious fallback. Confirm before you fish Triangle Lake.
