Fishing at Rocky Flats Lake, Jefferson County, Colorado

• Overview

  Rocky Flats Lake sits in Jefferson County, out in Colorado. What surrounds it is rolling hill. With some 43 acres of water, there is room for a boat but no need of one. Shoreline comes to about 1.5 miles, small enough to learn in a day. The closest town, Superior, is 6.4 miles away. Coal Creek lies 8.1 miles off, Golden another 8.1 miles. The boundary is close enough to be worth checking before you fish.

• Where to Fish on Rocky Flats Lake

  Depth is not on record here, so the bank has to tell you. The old creek line under the surface is the feature worth finding. Look for where the old bank line still shows under the surface. Species logged across Jefferson County include rainbow trout, brown trout, common carp and green sunfish. The list covers the county rather than this water alone, so treat it as a guide. On Rocky Flats Lake a short move beats a long cast.

• Seasonal Patterns

  The range across the year is 31°F to 70°F. The year turns gently, without extremes at either end. Some winters give nothing at all, so plan for open water. The hot months push the fishing to dawn and dusk. That shapes the year on Rocky Flats Lake. Sudden cold puts fish down faster than sustained cold does.

• Tackle & Baits

  Whether you may fish here is not something records settle. Parking is not close: half a mile from the bank, and no nearer option is mapped. Light line and small metal for the trout; a fly rod earns its place on calm evenings. A phone call first saves an afternoon. Fishing rules and camping rules are set separately here. Failing this one, try Ralston Reservoir, 3.3 miles away. For Rocky Flats Lake in particular, ask before you travel.
