• Where to Fish on Diamond Lake

  Without a survey to go on, judge depth from how the bank falls away. On a natural lake the weed line and the shelf beyond it do the work. Weed, then depth: that is the order to fish a water of this kind. Across Sublette County, recorded fish include brook trout, rainbow trout, brown trout and lake trout. County data is a starting point rather than a guarantee. At Diamond Lake light and wind decide more than tackle does.

• Seasonal Patterns

  The seasonal spread runs 15°F to 51°F. Seasons are distinct, and each one fishes differently. Winter locks it down, and early June brings it back. Open water usually runs from early June until about early November. May into June fishes hardest, and September gives a second good stretch before the lid returns. The season on Diamond Lake follows the weather closely.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. A camping area sits within half a mile of here. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Local rules can differ across the county line, so check where you stand. Some stretches are reserved and marked as such on the ground. If the gate is shut, V Lake at 1.2 miles is the nearest alternative. Treat access at Diamond Lake as something to verify.
