Calder is a small reservoir located on Pot Creek on Diamond Mountain. It is the second reservoir of three on Pot Creek, along with Matt Warner and Crouse. Calder is managed as a Blue Ribbon trophy trout water. It is known for fast fishing for big, fat trout. Calder sits in a pretty basin surrounded by lodgepole and pinion and juniper trees. You also have an opportunity to see some of the many deer, elk and sage grouse in the area. This water is a little gem, Calder gets only moderate angling use.
Latest fishing report
On Aug. 10, anglers reported good fly fishing with nymph patterns from a float tube. They caught big rainbows, tiger trout and cutthroat that averaged 19 inches. Biologists recommend fishing past the weed line. We may start seeing blue-green algae blooms this time of year. If you see anything that looks suspicious, or come across any dead fish, please contact the Division's Vernal office. The reservoir has special catch-and-release regulations. You must use flies and lures only — bait is not allowed. See the Utah Fishing Guidebook for details. (Last update 08-14-18)
