, 1 <br /> attributable to the shareholder wells averaged approximately 5,000 acre-feet annually. Due to the <br /> limited supply of recharge credits from operation of the recharge plan,well pumping has been <br /> restricted. Additional recharge as well as recharge with longer lag times is needed to improve the <br /> generation of recharge credits. <br /> 4 PROJECT DESCRIPTION—Analysis of Alternative and Selected Alternative <br /> 4.1 Analysis of Alternatives <br /> In seeking a way to expand UP&B's ability to provide recharge credits for it shareholders, <br /> several alternatives were developed and analyzed. The alternatives considered include: <br /> 1. The "Do Nothing"alternative <br /> 2. Lease Augmentation Credit alternative <br /> 3. Hospital Road Recharge Pond and Headgate Bridge Expansion Alternative <br /> Alternative 1. The"Do Nothing"alternative is considered unacceptable. This alternative would <br /> not address the restriction on well pumping due to inadequate or ill-timed recharge accretions. <br /> Also,this alternative would not address the inadequate infrastructure at the UP&B headgate. <br /> Alternative 2. The Lease Augmentation Credit alternative was not selected because UP&B <br /> desires to have long term stability of their augmentation credits. An alternative that depends on <br /> other entities having excess augmentation credits will not be a reliable source and would be <br /> subject to factors beyond UP&B's control. This would not provide the stability needed to meet <br /> out-of-priority depletions. <br /> Alternative 3. The Hospital Road Recharge Pond and Headgate Bridge Expansion Alternative <br /> was chosen because it meets the need for the UP&B recharge plan, is technically feasible, as well <br /> as providing infrastructure for the continued operation of both irrigation and recharge under the <br /> UP&B system. <br /> 4.2 Selected Alternative <br /> The purpose of this project is to provide an additional structure for the recharge operations run <br /> by UP&B and to improve the ditch headgate to aid operations and maintenance. Project <br /> improvements will consist of the following: <br /> 1. Construction of the Hospital Road Recharge Pond and associated facilities. <br /> 2. Expansion of UP&B headgate bridge. <br /> Hospital Road Recharge Pond. The purpose of the Hospital Road Recharge Pond is to generate <br /> recharge accretions that can offset out-of-priority depletions caused by well pumping under the . <br /> UP&B system. Deliveries to the pond will infiltrate into the aquifer and percolate into the South <br /> Platte River as recharge accretions. The proposed Hospital Road Recharge Pond would be <br /> located on the north side of the City of Brush and just north of the Brush Lateral of the Upper <br /> Platte and Beaver Canal system(see Figure 2). The parcel on which the pond sits was purchased <br /> by the Castle Rock Construction Company(Castle Rock) for development. UP&B has a <br /> purchase agreement for ten acres for the recharge facility. Part of the agreement was that Castle <br /> Rock would excavate the pond. The pond design plan, as drawn and constructed by CRCC, is <br /> shown in Figure 3. At this time the excavation is mostly completed. The pond is planned to be <br /> about 9.6 acres with 4:1 side slopes and a depth of about ten feet. UP&B will deliver water from <br /> the Brush Lateral into the Hospital Road Recharge Pond. A pond inlet structure will be <br />
