Out in Delta County, Colorado, sits Cole Reservoir Number 4. It sits in pine and birch. Small at around 5 acres: two anglers spread out cover most of it. Head to Cedaredge, 9.2 miles away, for anything you forgot. It is 153 miles to Boulder, the nearest city. It lies deep inside the county rather than near an edge. The near end sees the visitors; the far end rarely does.
Open data we checked carries no depth for this water. Inflow corners move water, and moving water gathers fish. Draw-down through summer strips the margins, so follow the water out. Open biodiversity records for Delta County list rainbow trout, white sucker, flannelmouth sucker, bluehead sucker and brown trout. What holds for the county may not hold for this water. Read this water for ten minutes before the first cast goes out.
On the long-term average, July reads 56°F and January reads 17°F. Fishing here follows the temperature more than the calendar. Look for the thaw near mid May; the fishing lifts straight after. Averages suggest open water from about mid May through to roughly mid November. Late spring and early autumn carry the year between them. Plan around that when you fish this water.
Nothing we hold confirms whether access is permitted. There is no mapped parking or launch nearby, which keeps numbers down. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Rules differ from one water to the next round here. Fishing rules and camping rules are set separately here. Dreyfus Reservoir sits 0.8 miles off and takes the overflow. Signs at this water carry more weight than any list.
