• East Branch Ute Creek above Upper Bypass Intake has a basin area of 0.86 square <br /> miles, and a mean basin elevation of 9400 feet. Streamflow at this station was <br /> monitored from July 1976 through October 1983. Average annual flow during this <br /> period was 5.48 cfs. Average monthly flows range from 0.11 cfs in January, February, <br /> March, and October to 1.95 cfs in June. <br /> A water management program was implemented during the period 1976 through the <br /> present. During this period, baseline Streamflow data was used to predict conditions on <br /> an annual basis to plan for efficient use of available water rights, to insure adequate <br /> process water for the milling process and potable water, and to ensure that extreme <br /> conditions of either low flow (disruption of the milling process), or high flow (resulting in <br /> loss of integrity of the mill area facilities) are anticipated and appropriate measures <br /> employed to avoid consequences of these events. <br /> Water rights, water monitoring, water forecasting, process water discharge procedures <br /> are integral components of this water management program. Potable water, flood <br /> bypass water, and process water supply systems are currently in place at the Mill. The <br /> • potable supply system consists of the Ute Creek Dam and Reservoir, the Williams Fork <br /> River, pipelines, pumps, and potable water storage tanks. The Ute Creek Reservoir is <br /> the primary source of potable water. The normal operating capacity is approximately 92 <br /> acre-feet, with a flood surge capacity of 325 acre-feet. The other potable water source, <br /> the Williams Fork River, can be pumped into the system if needed. <br /> The flood bypass system allows flood protection for the mill facilities. The upper flood <br /> bypass system consists of the East Branch Reservoir bypass, the upper Ute Creek <br /> bypass, the bifurcation structure and the delivery line to the Williams Fork River. The <br /> bifurcation structure divides the incoming flows. Water can either flow into the East <br /> Branch Reservoir or be diverted into the Williams Fork River. <br /> The East Branch Reservoir bypass consists of a diversion dam above the reservoir <br /> which admits water into a pipeline to be diverted around East Branch Reservoir to the <br /> bifurcation structure. The upper Ute Creek bypass transports excess runoff from the <br /> Ute Creek Dam service spillway to the bifurcation structure. <br />
