Gillette sits in the middle of Campbell County's high plains, and while it's not the first place most anglers think of when planning a Wyoming fishing trip, the area has a handful of accessible stillwater options worth knowing about. Gillette Fishing Lake, Little Thunder Reservoir, and Smith Reservoir are the three main spots in and around town, all of them lake fishing rather than moving water. That means you're targeting warm-water and cold-water species depending on the reservoir and the time of year, and the fishing tends to be most productive during the shoulder seasons when water temperatures are in a comfortable range for fish to feed actively. These are not remote backcountry lakes — access is generally straightforward, which makes them a reasonable option for families, beginners, or anyone passing through the Powder River Basin who wants to wet a line without a long drive. Expect open, wind-exposed water typical of northeastern Wyoming, so early mornings before the afternoon gusts pick up are usually your best window. Wyoming Game and Fish manages stocking in the region, so checking their current reports before you go will tell you what's been put in recently and what's likely biting.
Frequently asked questions
What fish species can I expect to catch at Gillette Fishing Lake, Little Thunder Reservoir, and Smith Reservoir?
The specific species mix varies by reservoir and can change based on Wyoming Game and Fish stocking schedules, so checking their current stocking reports before your trip is the most reliable approach. Generally, northeastern Wyoming reservoirs of this type are stocked with trout and may also hold warm-water species like bass, perch, or bluegill depending on the water body. Contact the Wyoming Game and Fish Sheridan or Casper regional office for the most current information on each lake.
What license do I need to fish these lakes?
You need a valid Wyoming fishing license, available through the Wyoming Game and Fish Department online or at local sporting goods retailers in Gillette. If you're a non-resident, the fee structure is different from resident licenses, so check the current year's fee schedule on the Game and Fish website. There are no separate access fees mentioned for these lakes, but confirm that before you go.
What time of day is best for fishing these reservoirs near Gillette?
Early morning is your best bet on all three lakes. Northeastern Wyoming is notoriously windy by midday, which makes casting harder and tends to push fish deeper or into sheltered areas. Getting on the water at first light gives you calmer conditions and more active fish, especially during warmer months.
What gear should I bring for lake fishing around Gillette?
A medium-weight spinning rod in the 6- to 7-foot range handles most stillwater situations well here. Bring a selection of jigs, small spoons, and PowerBait-style baits if you're targeting stocked trout, and add some soft plastics if warm-water species are present. Wind is a real factor, so heavier line or braid with a fluorocarbon leader will help you maintain control on breezy days.
Are these lakes suitable for beginners or kids?
Yes, all three are lake fishing spots with no technical water to navigate, which makes them accessible for newer anglers and families. Gillette Fishing Lake in particular is close to town and easy to reach. Stocked reservoirs also tend to produce more consistent action than wild fisheries, which helps keep younger anglers engaged.
