These services have been provided in support of <br />the City's acquisition and transfer of water rights in the Boulder Creek <br />and South Boulder C::ree~ watersheds, tributaries to the South Platte <br />River. Engineering work p~rformed has included determination of water <br />availabiHty,under average and drought conditions, conveyance losses, <br />, historic crop distributions, on-farm application efficiencies, <br />consumptive use, irrigation and municipa.l return, flows, and operational analyses of the <br />City's water supply conveyance and storage system; engineering reports development; and <br />providing expert witness testimony'in support of these evaluations. CDM has also represented <br />the City in the review of applications by other 1l1-unicipalities involving the transfer of water <br />from ditches and reservoirs on Boulder CrE!ek and South Boulder Creek to protect the City's <br />operation of its water rights. This entailed revi~wing reports, adding appropriate terms and <br />conditi~ns to proposed transfer decrees, or providing expert testimony, where necessary. <br /> <br />CDM was also retained to conduct the City's plan and evaluate the existirig water rights <br />portfolio based on historic diversion records and, the capability of its water rights to meet <br />current and future water demands under average and low-flow drought conditions. To analyze <br />the effects of potential drought conditions, it was necessary to develop a computer model <br />(SYSTEM) to simulate historical yields frOIn more than 16 agricultural water rights and the <br />operation of the City's conveyance and storagef~cilities under historical conditions. Yields were <br />measured against various demand levels w:hile exercising conservation measures and <br />operational changes to the system. Patterns of agricultural deliveries were obtained from <br />diversion records from the DWR's electrol:1ic databases. Yields were assessed in the' model ' <br />against municipal demands. Existing and f"-ture storage capacities were "-sed to regulate and <br />manage supplies and increase yields. Municipal return flows' weJ:e- identified to adequately <br />replicate return flow patterns from the original agricultUral uses in order to maintain historical <br />levels in the receiving streams. <br /> <br />Pertinent Project Attributes: Colorado drou~ht; natural resource and water supply policy <br /> <br />. <br /> <br /> <br />Mr. Thomas Phare <br />Director of Public Works <br />Louisville, Colorado <br />303-335-4601 <br /> <br />. <br /> <br />Section 3, Page-10 <br />
