G-1 shows the surface water system including atwo-mile radius azound the <br />• Cresson Project Amendment No. 8 permit boundary. Each of the drainages is <br />discussed separately below. <br />Cripple Creek <br />Cripple Creek is a perennial stream; however, the flows vary widely and <br />can become quite low. The flow variance does not appear to be seasonal, but <br />rather is related to precipitation events. CC&V has four monitoring stations on <br />Cripple Creek: one of which has been actively monitored since mid-1993 and the <br />others of which have been monitored since early 1996. Flows for the four <br />monitoring stations on Cripple Creek are shown graphically at the end of <br />Appendix 1 of Volume II of this document. As shown on these figures, the flows <br />generally increase in a downgradient direction. Flows at the two upgradient <br />stations appear to vary more widely than flows at the lower stations. Flows in the <br />• upper reaches are affected by discharges from the City of Cripple Creek's waste <br />water treatment plant. <br />Cripple Creek has stream standards and is classified as usable for <br />recreation (Class 2), agriculture, and as a Class 2 cold water aquatic stream. <br />Standazds exist for pH, dissolved oxygen, fecal coliforms, major cations, and <br />major anions as well as some metals and cyanide. Water quality measurements <br />for the Cripple Creek stations have been compiled and are presented in Appendix <br />1, Volume II of this document. The water quality monitoring in Cripple Creek <br />shows a bicarbonate and sodium+potassium dominated system at the upstream <br />station, and a sulfate and calcium dominated system at the downstream station. <br />The stations in between reflect the changing chemical composition from upstream <br />to downstream <br /> <br />23 <br />
