The 0.44 ac.ft is the total use for a water right <br /> w~h onty commercial use, only industrial use, or commercial use and industrial <br /> use, <br />Do Well and Domestic No DWR records are available for these water rights, Indoor domestic water <br /> Springs use is estimated to be 100 gallons/day/person with an average of 3,5 people per <br /> household which results in a diversion rate of 3.5x1 00x365/(7.48x43,560)=0.392 <br /> ac.tt The associated depletions are estimated to be 10% of the diversions or <br /> 0.1QxQ.392=0.039 ae-ft. The indoor diversion and depletion rates were spedfied <br /> by Mr, Wayne Schieldt, Division 4. Engineer. The outdoor water use is estimated <br /> using a lawn area of 2,000 square feet and a crop irrigation requirement for <br /> bluegrass in the Upper Gunnison Basin of 1,72 feet. Using an irrigation <br /> efficiency of 75% results in a diverison amount of <br /> 1.72x2,OOO/(4356OxO,75)=Q,105 ae-ft. Using a spray loss of 5% results in a <br /> consumptive use of outdoor diversions of 0.105x(O,75+0.05)=0.084 ae-ft. The <br /> total indoor and outdoor diversions are 0.392+0,105=0.50 ae-ft (rounded to <br /> nearest 1/100th acre-foot). The total indoor and outdoor depletions are <br /> 0.039+0,084=0.12 ae-ft (rounded to the nearest 1/100th acre-fooH. <br />0.1 All All Diversions records from DWR HYDROBASE. Structures have only water rights <br /> junior to Aspinall Un~ rightS. Diversions pro-rated between water rights based <br /> on decreed amounts, Structures induded in the DWR StaleCU program are not <br /> Included in this catenorv. <br />0.2 All All Diversions records from DWR HYDROBASE. Structures have only water rights <br /> junior to Aspinall Unit rights except that diversions exceed decreed amounts. <br /> Diversions prorated between junior water rights based on priority. Diversions <br /> limited to amount decreed to junior water rights. Structures included in the <br /> D\NR StateCU nrnnram are not included in this catenorv, <br />0.3 All All Diversions records from DWR HYDROBASE. Structures that have rights junior <br /> and senior to the Aspinall Unit rights. Diversions were first allocated to senior <br /> water rights and then remainder was pro-rated to junior water rights based on <br /> decreed amounts. Structures induded in the DWR StateCU program are not <br /> included in this cateaorv, <br />0.4 All All Diversions records from DWR HYDROBASE infrequent monitored water <br /> diversion report, Based on available monthly records; all diversions were <br /> estimated to be made by the water rights at the structure that are senior to the <br /> Asninall Unit riahts. <br />Dv5 All All Diversions records from DWR HYDROBASE infrequent monitored water <br /> diversion report. Based on available monthly records; all diversions were <br /> estimated to be made by the water rights at the structure that are junior to the <br /> Asninall Unit riohts. <br /> <br />Hellon & Williamsen.
