Diamond Lake, Wyoming: Fishing Spots and Seasons

• Overview

  The Johnson County end of Wyoming holds Diamond Lake. Around the bank it is lake country bush. It runs to roughly 33 acres — big enough to hold fish away from the bank, small enough to learn. Bank access stretches around 1.0 miles in total. It sits higher than most water we list in Wyoming. The closest town, Buffalo, is 22 miles distant. The big place round here is Billings, 117 miles distant. One jurisdiction covers this water end to end.

• Where to Fish on Diamond Lake

  Nothing in our records gives a depth for this one. The shallow end warms first and pulls fish in ahead of the rest. This is a lake, so the margins and the first drop matter most. Fish documented in Johnson County include brown trout, rainbow trout and brook trout. The county figures include rivers and lakes alike. The shape of Diamond Lake decides where the fish sit.

• Seasonal Patterns

  Climate records put August near 48°F and January near 13°F. Cold locks it up for a good stretch each year. Once it clears, about mid June, the fishing comes on quickly. On the long-run averages the water opens up around mid June and starts locking again about late October. May into June fishes hardest, and September gives a second good stretch before the lid returns. It sets the rhythm of the year at Diamond Lake.

• Tackle & Baits

  The access position is unclear from public sources. No dam controls it, and the level follows the season. Nothing is listed nearby for parking or launching a boat. A small crankbait along the drop and a worm in the thick stuff cover the bass. Look for a notice board at the entrance. Some ground is open by custom rather than by right, so tread carefully. If the gate is shut, Sapphire Lake at 0.7 miles is the nearest alternative. Rules at Diamond Lake are worth checking on the day.
