Fishing Flatiron Reservoir in Larimer County, Colorado

• Overview

  Larimer County in Colorado is where Flatiron Reservoir sits. This is open valley ground. Roughly 41 acres: a morning covers one end, an afternoon the other. The full circuit measures close to 1.2 miles on foot. Some 8.2 miles away sits Campion, the nearest settlement. The big place round here is Fort Collins, 17 miles distant. The nearest boundary is a fair way off.

• Where to Fish on Flatiron Reservoir

  Depth is unknown to us, and the shoreline is the better guide. The arms fish better than the open middle whenever the water is up. Built water gives depth close in, which suits a bank angler. Species logged across Larimer County include black-spotted cutthroat trout, brook trout and white sucker. These are county-wide records, so not all of them will be in this water. The shape of Flatiron Reservoir rewards a slow walk along one bank.

• Seasonal Patterns

  Averages move between 29°F in January and 70°F in July. Whether it freezes depends on the year. In milder years the edges alone go, and the middle never sets. March through May is the strongest run, with October and November a second stretch. Expect Flatiron Reservoir to follow that timing.

• Tackle & Baits

  Our records carry no access rule either way. Boat use is marked as prohibited in public data. Parking is close: a car park sits half a mile from the bank. A pier or jetty stands 170 yards away, which helps on a crowded bank. A campsite lies half a mile away for anyone staying over. There are toilets mapped about half a mile away. Local rules can differ across the county line, so check where you stand. Barbless rules turn up on managed water more often than not. None of that is settled for Flatiron Reservoir in what we hold.
