Pass Reservoir in Johnson County: How and When to Fish It

• Overview

  Pass Reservoir lies in Johnson County, in Wyoming. This is mixed forest country. It runs to roughly 27 acres — big enough to hold fish away from the bank, small enough to learn. By elevation it sits in the lower part of our Wyoming listings. Nearest town is Buffalo, 40 miles off. For a city, Billings is 163 miles off. No border sits close enough to matter.

• Where to Fish on Pass Reservoir

  Nothing in our records gives a depth for this one. Rip-rap along the wall holds fish that the open bank never does. The old creek line under the surface is the feature worth finding. Across Johnson County, recorded fish include brown trout, rainbow trout, brook trout and white sucker. It is the county picture; the agency list is water-specific. Pass Reservoir gives up its fish to patience rather than distance.

• Seasonal Patterns

  On the long-term average, July reads 68°F and January reads 23°F. Spring and autumn carry the fishing; summer and winter test it. Break-up comes around early April, and the run that follows is short and strong. Averages place the thaw at early April and the freeze at early December. Early summer and early autumn carry the open-water season. It sets the rhythm of the year at Pass Reservoir.

• Tackle & Baits

  No public source sets out the position on this bank. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Look for a notice board at the entrance. Access can change hands, so last year's answer may not hold. Dwight Reservoir sits 13 miles off and takes the overflow. Check the current arrangement for Pass Reservoir.
