A mix of sun and cloud over the water, with a gentle ripple from the NNW and the barometer heading up. Activity on Cold Sore Reservoir should centre on the channel swing where it comes near the bank. The productive run goes the day. Start on the obvious water and expand from there. Cooling water has fish active and on the move.

Cold Sore Reservoir is listed under Delta County, Colorado. The surface lies 10,807 feet up. It measures about 27 acres, which is a comfortable size for bank fishing. It ranks high for size among our Delta County listings. Cedaredge is the closest town at 12 miles. Boulder is the closest city, 160 miles away. The boundary is close enough to be worth checking before you fish.
Nothing in our records gives a depth for this one. Rip-rap along the wall holds fish that the open bank never does. Look for where the old bank line still shows under the surface. Records held for Delta County cover rainbow trout, white sucker, flannelmouth sucker and bluehead sucker. Records at this level tell you what is in the area. At Cold Sore Reservoir light and wind decide more than tackle does.
Averages move between 17°F in January and 56°F in July. The freeze arrives properly here and holds. Firm cover through the cold months, then open water from mid May. Ice usually gives way near mid May, and forms again about mid November. The weeks after the thaw and the ones before the freeze are the strongest. Anyone fishing Cold Sore Reservoir regularly works to that calendar.
Public sources are silent on who controls the bank. The map shows no ramp or car park nearby, so this is a walk-in water. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Ask in the nearest town if you are unsure. Some stretches are reserved and marked as such on the ground. Wolverine Lake sits 0.9 miles off and takes the overflow. For Cold Sore Reservoir in particular, ask before you travel.
