<br />CWCB North Fork <br />7/5/2005 <br />Page 3 <br /> <br />4. Perform preliminary analyses of water availability in the reaches affected by the <br />CWCB ISF filings. Existing CDSS models will be used for the analyses. Compare the <br />preliminary estimate of depletions from ponds, springs, and wells with the estimate of <br />available flow. This cursory look at existing depletions and available flow is to provide <br />the Board with a better understanding of the extent of potential impacts to current and <br />future uses. <br /> <br />Completion: <br />Assignment: <br /> <br />June 10 <br />CWCB (LRE) <br /> <br />STATUS: Complete. It was determined that the proposed ISF filings would <br />appropriate all available flows during the late irrigation season, but that there <br />would be available flows for future appropriations during average to wet runoff <br />months. <br /> <br />5. Review by CWCB Board at July meeting of level of progress and set hearing date and <br />appointment of hearing officer <br /> <br />Completion: <br />Assignment: <br /> <br />July Board meeting <br />CWCB <br /> <br />STATUS: Board item for July meeting <br /> <br />. Phase 2 Detailed Analysis of Existing Depletions and Future Water Needs and Filing of <br />Water Rights Applications <br /> <br />6. Document existing uses in the reaches affected by the ISF filings including decreed <br />uses and undecreed existing uses. The Division 4 Engineer's Office and Water <br />Commissioners will provide input on the number of existing water rights and <br />estimated current consumptive use on an HUC basis. They will lead the effort to <br />identify those areas that don't have augmentation plans and are junior to the Short <br />Ditch. Estimates will be made of existing depletions, both decreed and undecreed. <br /> <br />Completion: <br />Assignment: <br /> <br />August 1 <br />Division 4 Engineer's Office <br /> <br />STATUS: CDM performed additional sub-basin delineation beyond the HUC <br />watersheds as requested by Division Engineer. Division Engineer has provided <br />estimates, by sub-basin of estimated existing water uses, both decreed and <br />undecreed, in the North Fork of the Gunnison River basin that are in need of <br />augmentation water. The estimated existing water uses do not include irrigation <br />rights, only springs and ponds used for domestic, stock and evaporation uses. <br /> <br />S :\GI S\working\Jinal_ memo\CW CB _ N _Fork070505.doc <br />
