Saint John Reservoir near Carbondale: Fishing Spots, Seasons and Access

• Overview

  Saint John Reservoir sits in Eagle County, out in Colorado. Country round the bank runs to rolling bush. About 3 acres of surface, which puts the far bank inside easy sight. 6.5 miles away sits Carbondale, the nearest town. For a city, Boulder is 112 miles off. You are close to a county edge here; who manages the access can change within a short drive.

• Where to Fish on Saint John Reservoir

  Without a survey to go on, judge depth from how the bank falls away. The arms fish better than the open middle whenever the water is up. The old creek line under the surface is the feature worth finding. Reported across Eagle County: brook trout, brown trout, rainbow trout and cutthroat trout. County data is a starting point rather than a guarantee. On Saint John Reservoir that means starting tight and working out.

• Seasonal Patterns

  The warmest month averages 57°F, the coldest about 15°F. Hard water is a season in its own right here. Ice fishing carries the winter, and the water opens about early May. Average temperatures cross freezing around early May in spring and again near mid November in autumn. The open run goes from the thaw to the freeze, and April through October covers most of it. Plan any trip to Saint John Reservoir around it.

• Tackle & Baits

  Ownership and access are not documented in what we hold. Nothing in the way of made access shows up nearby: no ramp, no car park, no path. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Season dates differ by species, so read the table. Where the way in crosses private ground, ask first. Lewis Lake at 2.3 miles is the sensible second choice. Check the position at Saint John Reservoir before loading the car.
