Low, flat cloud sitting over the water, with a light chop building from the NNE as pressure slides. Activity on Rock Lakes should centre on sheltered bays and points. The productive run goes night into morning. Start on the obvious water and expand from there. Autumn fish are feeding up and less fussy than in summer.

Rock Lakes is one of the Duchesne County listings for Utah. Beyond the shoreline you have pine and birch. The water measures roughly 6 acres, so nothing here is far from anything else. Our Duchesne County list holds plenty of bigger water. Kamas lies 32 miles from the water. Provo is the closest city, 60 miles away. The nearest edge is a long way off, so local rules apply throughout.
No depth figure appears in our records, so the bank has to tell you. A natural lake fishes on cover, and cover here means weed and timber. Look for the band where the shallows give up and the bottom falls away. Across Duchesne County, recorded fish include brook trout, brown trout, rainbow trout, Arctic grayling and black-spotted cutthroat trout. The county list is broader than any single water. On Rock Lakes that means starting tight and working out.
Expect July near 53°F and December near 17°F on the long-run figures. A full turn of seasons, with the strongest sport on either side of summer. The lid arrives early and lasts until roughly early June. Open water usually runs from early June until about early November. Fish feed hardest at the start and the close of the open season. Expect Rock Lakes to follow that timing.
Nothing we hold confirms whether access is permitted. Mapping records no facilities at all near this water. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Gates get locked out of season on water like this. Where parking is tight, arriving early solves most problems. Shamrock Lake sits 1.1 miles off and takes the overflow. Nothing here settles the position at Rock Lakes for certain.
