Jiggs Reservoir belongs to Campbell County, Wyoming. Height above sea level is 4,160 feet. About 9 acres of surface, which puts the far bank inside easy sight. It lies lower than most water we list in Wyoming. The town to know is Moorcroft, 14 miles out. Billings sits 189 miles out, and it is the nearest city worth the name. The nearest boundary is a fair way off.
Nothing we hold settles how deep this runs. The old creek line under the surface is the feature worth finding. Draw-down through summer strips the margins, so follow the water out. Survey and observation records for Campbell County include green sunfish, black bullhead and white sucker. These are county-wide records, so not all of them will be in this water. On Jiggs Reservoir the first feature you find is usually worth a session.
Between January at about 20°F and July at about 70°F, the water has a wide range to work through. A full turn of seasons, with the strongest sport on either side of summer. The lid usually sets by midwinter and gives way around early April. On the long-run averages the water opens up around early April and starts locking again about early December. Just after the ice goes and just before it returns, the fishing lifts. It holds true on Jiggs Reservoir more years than not.
Who may fish here is not settled in anything we hold. Public mapping marks it as seasonal water rather than permanent. No launch point is recorded nearby, so this is a bank water unless you carry a boat in. For the trout, small spinners and a box of nymphs cover both approaches. Rules for this water may differ from the county norm. Night access is frequently treated as a separate matter. The nearest alternative is Allee Reservoir, 4.8 miles out. The position on Jiggs Reservoir is worth confirming on the day.
