<br />from the ponds is returned to the river by underground <br />percolation which due to a time delayed effect causes the <br />majority of this water to show up in the river during the <br />summer time. This is the time when the SDC has depletions <br />that need to be offset with additional augmentation water. <br />The development of recharge ponds also provides habitat for <br />migratory waterfowl. The SDC would drill 2 wells to <br />discharge water directly into their ditch for recharge <br />purposes. The SDC would also drill a well for supplying <br />augmentation water directly to the senior calling water <br />right. This is a drought management tool currently being <br />used by GASP with approval from the State Engineer to help <br />provide augmentation water during the most severe drought <br />situations. The cost of this alternative is $135,000. <br /> <br />The Selected Project <br /> <br />The SDC plans to construct alternative #3. Features of this <br />alternative are as follows: <br /> <br />Two new recharge ponds with small earthen dams will be <br />constructed on existing irrigated farm ground. <br /> <br />An existing unused recharge pond will have a small pumping <br />station installed in the ditch to lift water into it. <br /> <br />Two wells will be drilled next to the river bank and piped <br />backed to the ditch. This will be done to provide water <br />during times in the winter when the river freezes. <br /> <br />An augmentation well will be drilled away from the river to <br />provide direct releases for the senior calling water right. <br /> <br />All of the above features will be equipped with proper <br />measuring devices along with the end of the ditch. <br /> <br />Water Rights. <br /> <br />There are 52shareho1ders in the SDC with rights to divert 62.5 <br />cfs from the South Platte River under an 1886 decree. The <br />official name on the decree is the SPRINGDALE DITCH COMPANY with <br />their water being diverted down the SPRINGDALE DITCH. <br /> <br />Feasibility Study <br />Springdale Ditch Company <br />Augmentation Project <br />May 2003 <br /> <br />5 <br />
