3. Yampa River Structure Information <br />and Basin Meeting Notes <br />This section contains information that was gathered during the initial CDSS development <br />phase, regarding specific, individual diversion structures. The objective at the time was to <br />identify which structures should be included explicitly in the water resources planning model <br />of the Yampa River. The information is historical, reflecting the thinking at the time and <br />conditions at the time. It is valuable, however, for its detail on specific structures from those <br />who have observed the diversion systems and have first-hand familiarity with their <br />operations. <br />3.1. Annotated Structure Listing <br />The number of diversion structures explicitly included in the CDSS water resources <br />planning model for each basin was based on the State's recommendation to simulate 75 <br />percent of the decreed water rights. In the Yampa basin, by accumulating net absolute <br />rights for each structure and ranking the structures, it was determined that structures with <br />rights amounting to 5.0 cfs or more comprised 75 percent of the basin's rights. The table <br />in this section lists structures that meet that criterion for inclusion. The list was then <br />annotated, however, to document input from Division 6 personnel based on observations <br />of actual practices. These observations maybe generally useful to CDSS users who are <br />trying to enhance their understanding of water use in the Yampa River basin. <br />Table 3.1 <br />Yampa Basin Diversion Structures with Water Rights >_ 5 cfs <br /> <br /> <br /> <br />DID <br /> <br /> <br />tructure Name <br />Decree <br />Amount <br />(cfs) <br />Cumulative <br />% <br />of Total is <br />Structure <br />in Final <br />Model? <br /> <br /> <br />omments <br />440694 MAYSELL CANAL 129 0.0203 Yes <br />581583 sTAGECOacx <br />HYDROELECTRIC 110 0.03761 Yes <br />440522 CRAIG sTATION D & PL 90.63 0.05188 Yes <br />570539 GIBRALTAR DITCx g0 0.06447 Yes <br />440675 JUNIPER MTN TUNNEL 67.67 0.07512 Yes <br />580920 wALTON CREEK DITCH 67 0.08566 Yes <br />440692 MARTIN CK DITCH 62 0.09542 Yes <br />440589 DEEP cuT IRR D 60.45 0.10494 Yes <br />580506 ALLEN sASIN suPPLY D 60 0.11438 Yes <br />570592 sxELTON DITCx 53.52 0.1228 Yes <br />580530 sAxTER DITCx 49.6 0.13061 Yes <br />440586 D D & E DITCx 49.33 0.13837 Yes <br />570611 WALKER IRRIG DITCH 43.5 0.14522 Yes <br />Yampa River Basin Information 3-1 <br />
