Rock River, Wyoming sits in the high plains of Albany County, and the fishing around it is almost entirely still water — four lakes and reservoirs within reasonable reach of town. McGill Lakes, Lace Reservoir, Bosler Reservoir, and Post Lake make up the local options, and all four are lake fishing setups rather than moving-water wade fishing. This is not a destination you come to for technical dry-fly work on a storied river. What you do get is accessible, relatively uncrowded water where you can set up on a bank or launch a small boat or float tube without a lot of competition. The area sits at high elevation on the Laramie Plains, which means the season is compressed — ice-out can run late and conditions can turn fast even in summer. If you're driving up from Laramie or coming through on I-80, these waters are worth building a half-day or full-day around, but go in with realistic expectations: this is plains reservoir fishing, and the experience reflects that. Check Wyoming Game and Fish regulations before you go, since licensing requirements and any special rules apply to all four waters.
All four fisheries in the area — McGill Lakes, Lace Reservoir, Bosler Reservoir, and Post Lake — are lake or reservoir fishing. There is no listed stream or river fishing in the immediate Rock River area, so plan accordingly if you're set on moving water.
The supplied activity data doesn't specify species by water body, and we won't guess. Wyoming Game and Fish publishes stocking reports and species information by water body on their website, which is the most reliable source before your trip.

The Laramie Plains sit at high elevation, so ice-out tends to run later than lower-elevation Wyoming waters — late April into May is a reasonable expectation, though it varies by year. Summer mornings and evenings are generally the most productive windows on still water, and afternoon wind on the plains can make casting difficult and push fish deeper.
A float tube, pontoon boat, or small car-top boat will open up more water than bank fishing alone at most of these reservoirs. Medium spinning or baitcasting gear covers most still-water situations here. Bring layers regardless of the forecast — weather on the Laramie Plains changes quickly and the wind is rarely absent.
Yes, a valid Wyoming fishing license is required to fish any of these waters. Wyoming Game and Fish sets regulations that can include size limits, bag limits, or gear restrictions specific to individual water bodies, so check the current regulation booklet for McGill Lakes, Lace Reservoir, Bosler Reservoir, and Post Lake before you go rather than assuming standard statewide rules apply.
