• Where to Fish on Peterson Post Flat Reservoir

  The records we hold are silent on depth, so plan to find it yourself. The productive water is a rod length or two out, not a hundred. Weed, then depth: that is the order to fish a water of this kind. Moffat County records list flannelmouth sucker, bluehead sucker, white sucker and common carp among the fish reported. Species recorded across the county may be limited to a few waters. Read Peterson Post Flat Reservoir before you fish it and the day goes better.

• Seasonal Patterns

  Temperature averages peak at 68°F in July and bottom out at 20°F in January. Winter closes the water for a while, and the reopening is worth catching. Look for the thaw near early April; the fishing lifts straight after. The lid tends to go about early April and return around early December. Spring is short and heavy here; autumn is longer and steadier. That shapes the year on Peterson Post Flat Reservoir.
