percolation which due to a time delayed effect causes the majority of this water to show up in the river during the summer time. This is the time when the UPBCC has depletions that need to be offset with additional augmentation water. The development of recharge ponds also provides habitat for migratory waterfowl. The UPBCC would construct a measuring device at the new ponds along with measuring devices at the ends of its system. These measuring devices are required for proper augmentation calculations as described in the UPBCC augmentation decree and as required by the State Engineer. The cost of this alternative is $75,000. The Selected Project The UPBCC plans to construct alternative #3. Features of this alternative are as follows: Two earthen dams (non-jurisdictional) will be constructed across Badger Creek to form two recharge ponds. Each dam will have a 24 inch PVC outlet pipe with a slide gate for any potential direct releases to the creek. Each dam will have an emergency spillway for the passing of storm events down the creek. The pond and dam closest to the canal will have a "morning glory" discharge pipe. This will allow the first pond to fill and once full water will flow into the second pond. A current turnout from the canal will be modified to TIleaSUre water into the recharge ponds. Four small measuring weirs will constructed at the ends of the UPBCC system. Water Rights There are 100 shareholders in the UPBCC with rights to divert 234 cfs from the South Platte River consisting of a 20 cfs right (1868/1869), a 50 cfs right (1882), and a 164 cfs right (1888). The official name on the decree is the UPPER PLATTE AND BEAVER CANAL COMPANY with their water being diverted down the UPPER PLATTE AND BEAVER CANAL.
