Low, flat cloud sitting over the water, with a faint WNW drift and pressure ticking upward. The fish at Upper Coney Lake are likely to sit near the calm side of the wind. The morning should out-fish the rest of the day. Trust the forecast and stay out through the window. Cooling water has fish active and on the move.

Upper Coney Lake lies within the bounds of Boulder County, Colorado. The surface lies 10,971 feet up. It covers about 13 acres, so this is small water you can walk round in under an hour. Some 12 miles away sits Nederland, the nearest settlement. Fraser is 15 miles away, with Granby at 17 miles. This one is safely inside the county line.
Nothing we hold settles how deep this runs. A soft bed grows weed late into autumn, which keeps fish shallow. The shallow end warms first and pulls fish in ahead of the rest. Public occurrence data for Boulder County names black-spotted cutthroat trout, brook trout, brown trout and bluegill. The county figures include rivers and lakes alike. On Upper Coney Lake the first feature you find is usually worth a session.
Long-term averages put July at about 51°F and January near 17°F. A full turn of seasons, with the strongest sport on either side of summer. The lid usually sets by midwinter and gives way around late May. Averages suggest open water from about late May through to roughly early November. Spring is short and heavy here; autumn is longer and steadier. The season on Upper Coney Lake rarely departs from it.
Public sources are silent on who controls the bank. No car park, ramp or path is recorded within easy reach of the shore. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Gates get locked out of season on water like this. Access can change hands, so last year's answer may not hold. Failing this one, try Blue Lake, 1.3 miles away. Treat Upper Coney Lake as unsettled until someone local tells you otherwise.
