Prospector Lake, Wyoming: Fishing Spots and Seasons

• Overview

  In Wyoming, Prospector Lake falls inside Sublette County. The water sits 9,508 feet up. About 6 acres of surface, which puts the far bank inside easy sight. Our Sublette County list holds plenty of bigger water. Head to Pinedale, 14 miles away, for anything you forgot. After that come Marbleton at 39 miles and Fort Washakie at 45 miles. This one is safely inside the county line.

• Where to Fish on Prospector Lake

  Our records hold no depth for this water. Bays and points beat straight shoreline every time on water like this. Look for the band where the shallows give up and the bottom falls away. Survey and observation records for Sublette County include brook trout, rainbow trout, brown trout, lake trout and white sucker. It is the county picture; the agency list is water-specific. On Prospector Lake the obvious spot is not always the productive one.

• Seasonal Patterns

  Climate records put July near 54°F and January near 16°F. The year splits cleanly: hard water, then open water. Count on hard cover from midwinter, and open water from mid May. Climate averages put the opening at about mid May and the closing near mid November. The middle of summer slows a little, with dawn and dusk carrying it. That shapes the year on Prospector Lake.

• Tackle & Baits

  Ownership and access are not documented in what we hold. No slipway, car park or made path shows up nearby in mapping, so treat access as rough. For the trout, small spinners and a box of nymphs cover both approaches. A phone call first saves an afternoon. Where the way in crosses private ground, ask first. Failing this one, try Glimpse Lake, 0.6 miles away. What applies at Prospector Lake may have changed since it was mapped.
