• Where to Fish on Dillon Bay

  There is no published depth for this one, so start shallow and work out. The mouth fishes hardest when the run is at its strongest. Slack water is dead water on a place like this. Reported across Summit County: brook trout, rainbow trout and brown trout. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. Take Dillon Bay a stretch at a time.

• Seasonal Patterns

  Averages here run 56°F at the top of summer and 17°F at the bottom of winter. Seasons are distinct, and each one fishes differently. Count on hard cover from midwinter, and open water from early May. From about early May to around mid November, expect open water on the long-run figures. The open run goes from the thaw to the freeze, and April through October covers most of it. On Dillon Bay that shapes the whole year.

• Tackle & Baits

  No access rule appears in what we hold. This is a reservoir by origin, with the deepest water near the dam. Parking sits half a mile out, which makes for a walk with tackle. There is camping recorded roughly half a mile off. Facilities run to toilets 0.9 miles from the water. Some banks are open only from a marked point. A polite question at the farm gate opens more banks than anything else. For a change of water, Old Dillon Reservoir is 0.6 miles distant.
