Evaluation of Potential Subsidence Impacts of Longwall Mining in the Spruce Stomp Lease Area <br />to Aquatic Life and Water Supply <br />maximum temperatures range from 90 °F in July to 407 in January with average minimum <br />temperatures from 577 in July to 16 °F in January (NCDC 1981 — 2010 Monthly Normals). <br />Average snowfall over the entire period of record at the gage is calculated to be over 47 inches <br />annually. This gage is the closest official weather station to the site. <br />Higher elevations receive more snowfall, though, and data provided by the NRCS show that <br />annual precipitation in the West Fork Terror Creek watershed is approximately 24 — 36 inches, <br />based on data averaged from 1971 — 2000 (PRISM). The average annual maximum temperature <br />ranges from 46° — 56 °F with average annual minimum temperatures between 28 -34 °F (PRISM, <br />71 -00 data). <br />4.1.7 Water Bodies (Reservoirs, Creeks, Ditches and Springs) <br />Significant water bodies in the West Fork Terror Creek watershed include West Fork Terror <br />Creek, Holy Terror Reservoir, the Overland Ditch and tributaries to West Fork Terror Creek <br />including Cunningham Creek and other unnamed "blue line" features identified on the USGS <br />7.5- Minute Topographic Quadrangle mapping for the area (see Figure 3). <br />The Overland Ditch intercepts natural surface flows from the upper third of the West Fork Terror <br />Creek watershed when it is in priority (i.e., a downstream water right owner has not placed a <br />`'call" on the water). According to Steve Tuck, the water commissioner for the North Fork <br />watershed, the Overland Ditch is legally able to intercept surface now until late June or early <br />July during most years. Additional capture and export of water from the West Fork Terror Creek <br />watershed is achieved at the Holy Terror Reservoir, which is located near the upper extreme of <br />the watershed. This reservoir captures water from the uppermost portions of the West Fork <br />Terror Creek watershed and diverts it north to the Leroux Creek watershed. <br />4.2 West Fork Terror Creek in Vicinity of Potential Project Area <br />The Potential Project would expand B -seam longwall mining into the Spruce Stomp Lease Area <br />and under approximately 2.5 miles of West Fork Terror Creek with the upstream limits of <br />121 - 014.000 Wright Water Engineers, Inc.
