When one lake or stream isn't producing, just move on to the next. There are over 400 fishable waters on the South Slope of the Uintas. Still mostly good trail access and mosquito populations are down due to frost and cold nights. Be prepared for weather changes, especially ice and snow. Bait anglers are also having good success from shore.
Weather can be very cold and wet here so bring appropriate clothing.
Many lakes have trout and grayling aggregate limit of 4. Fishing below Taggart has slowed, but pressure is light. Lower stretches too warm for good fishing. Good fishing between Echo and Rockport. There's aggressive pre-spawn activity by brown trout this time of year.
