groundwater system is saturated under water table (uncon- <br /> fined) conditions . The aquifer system is in direct communica- <br /> tion with the perennial Dutch, Coal , Bear and Porcupine <br /> Creeks . The saturated alluvial materials are highly permeable <br /> and discharge groundwater to the surface drainages during <br /> base flow (low flow) periods . The alluvial deposits , in <br /> essence, provide the basic temporary groundwater storage <br /> following the peak flow events and discharges water slowly <br /> during the recession of the snow melt runoff period naturally <br /> augmenting flow of the Crystal and Roaring Fork Rivers <br /> through the late summer and fall months . <br /> Mid-Continent has completed nine ground <br /> water observation and production wells in the alluvium . The <br /> , .. well depths range from 10 feet to 75 feet with an estimated <br /> + 10 gpm production . The wells were installed by a licensed <br /> water well driller with casing ranging from 4 ' to 6 ' in <br /> diameter . The casing is steel and PVC, cemented in place <br /> and sealed using standard water well drilling methods . <br /> In addition to other shallow alluvial <br /> aquifers , surface water flow is also being contributed to by <br /> springs . In several areas , such as SEA, Sec . 14 , T10S . , <br /> R90W it has been reported by Willard Owens (1980) that the <br /> seeps have developed "in a landslide deposit as indicated by <br /> the topography of the area ." Similarly several springs have <br /> developed associated with talus and rock slides in the <br /> permit area . The recharge to these areas is supplied locally <br /> 3 <br /> i <br />
