Allen Creek Reservoir is an artificial impoundment built for irrigation in the 1940's or 1950's downstream from the junctions ofAllen, Beetle, and Yellowjacket Creeks. The reservoir has no facilities but the BLM area which occupies about 200 yards of shoreline is available for camping. The reservoir is located about 45 miles east of Prineville in the Big Summit Prairie. There is motorized access from May 15-September 15 but the remainder of the time access is only by foot or non motorized vehicles. A primitive boat ramp is located on the southeast corner of the reservoir and you can see Osprey nests in the area. There is good fishing for redband or brook trout and you may get a brook trout that may vary from 7-17 inches with the average size of 9 or 10 inches. Trolling with lures from a boat or float tube is very effective, and from the shoreline a variety of lures, bait, and flies are also effective. Lures include spinners and spoons with less that 6 pound test line, fished at a variety of patterns and depths will be successful. The depths will depend on location of food sources, time of day, water clarity, and temperature. Bait commonly used includes worms, cheese, eggs, and power bait, but fly anglers should look for emerging aquatic insects or recent hatches. The most important thing about the reservoir is stay off of private property and only enter the reservoir through BLM's access, all other access is by boat only.
