Fishing Upper Dinwoody Lake in Fremont County, Wyoming

• Overview

  Upper Dinwoody Lake is set in Fremont County, Wyoming. Land around it is dry rangeland. With some 174 acres of water, there is room for a boat but no need of one. With 4.0 miles or so of shoreline, boat anglers cover ground the bank cannot. On our Fremont County list it sits near the top for size. Fort Washakie sits 35 miles from the bank. The nearest city of size is Billings, 173 miles away. No boundary runs near, so the county rules hold throughout.

• Where to Fish on Upper Dinwoody Lake

  No depth figure appears in our records, so the bank has to tell you. Where the bottom changes texture, fish gather; find that line. The productive water is a rod length or two out, not a hundred. Public occurrence data for Fremont County names brown trout, rainbow trout, white sucker and brook trout. These are county-wide records, so not all of them will be in this water. On Upper Dinwoody Lake the first feature you find is usually worth a session.

• Seasonal Patterns

  Averages here run 61°F at the top of summer and 22°F at the bottom of winter. Expect a real winter and a strong spring after it. After mid April the shallows warm and the fish move up. From about mid April to around late November, expect open water on the long-run figures. May into June fishes hardest, and September gives a second good stretch before the lid returns. It sets the rhythm of the year at Upper Dinwoody Lake.

• Tackle & Baits

  We hold no note on access for this one. Records list it as a natural water body rather than an impoundment. There is no mapped parking or launch nearby, which keeps numbers down. Light line and small metal for the trout; a fly rod earns its place on calm evenings. A landowner's word beats anything printed elsewhere. Night access is frequently treated as a separate matter. Dinwoody Lake, 1.9 miles away, makes the obvious fallback. Confirm before you fish Upper Dinwoody Lake.
