Colorado trout anglers eye early mornings as drought heat squeezes rivers

Our gauge reading came back hot: 78°F water and 1,680 cfs of flow, well above the 68°F threshold Cutthroat Anglers (CO) flags as the point to stop fishing and protect stressed trout. That reading lines up with what shops across the state are reporting. Crystal Fly Shop (CO) notes CPW voluntary closures already in effect on stretches of the Roaring Fork, Crystal, and Colorado Rivers as low, warm water pushes fish into cooler pockets, and flies are being downsized as rivers keep dropping. Pat Dorsey Fly Fishing (CO) has been tracking a drought many consider the worst on record for the state. Anglers Covey Blog (CO) describes the classic "dog days" pattern taking hold, rivers slowing and fish turning lazier through the heat of the day. Bottom line for anglers on Colorado and Arkansas River water: fish early, watch your thermometer, and expect the bite to concentrate into a narrow morning window until temperatures ease.
