The embankments typically have a low spot to <br />serve as an overflow spillway. The ponds are located in ephemeral <br />drainages typically near a spring. They have a surface area of about 500 to <br />2,000 square feet and vary in depth from two to eight feet. <br />Hubbard Creek, Terror Creek and the creek in Stevens Gulch are perennial <br />streams which drain approximately 35, 29 and 8 square miles respectively. <br />All three creeks are important sources of irrigation water. The flow in Terror <br />Creek is supplemented during periods of low flow by discharges from the <br />Terror Creek Reservoir (Bruce Park Reservoir) which is formed by earthen <br />embankments. <br />The Terror Ditch is an unlined earthen structure with a capacity of about 6 to <br />8 cfs. The Ditch delivers irrigation water to Garvin Mesa. The first 2,500 feet <br />of the ditch is constructed along a very steep hillside above Terror Creek. <br />This section of the ditch was constructed by pioneering a road into the <br />location of the headgate and then excavating the ditch along the inside of the <br />road. Once the ditch emerges onto Garvin Mesa it splits into various laterals <br />and delivery ditches. <br />Terror Creek Reservoir is formed by the Bruce Park Dam. The Bruce Park <br />Dam consists of a main dam and a saddle dam. The original dam was <br />constructed in the 1940s. The dam was raised to a reported structural height <br />of 58 feet between 1950 and 1952. The reservoir has a reported storage <br />capacity of 598 acre -feet with a water surface area of 33 acres. The outlet <br />works consists of a 14 -inch diameter, welded steel pipe with a reinforced <br />concrete encasement. The intake to the outlet works is a hand operated <br />hoist slide gate. In 1990 Bruce Park Dam was re- classified as a Class I (high <br />hazard) dam. The Operator recognizes that the Bruce Park Dam and <br />Reservoir is under a Forest Service Special Use Authorization to Terror <br />Creek and Reservoir Company. <br />2.05-136- 06/10 <br />
