<br />. 'J <br /> <br />, <br /> <br />'. <br /> <br />TASK DESCRIPTION - Continued <br /> <br />7. Determine Water Availability - Water to fill enlarged reservoir <br /> <br /> <br />will come through existing ditches. Water supply study must <br /> <br /> <br />analyze existing water rights, ditch capacities, and average <br /> <br /> <br />runoff from presently ungagedstreams. Statistical correlations <br /> <br /> <br />will be required. This information will be utilized to <br /> <br /> <br />determine the safe annual yield to the project. A map of <br /> <br /> <br />watershed areas and a straight line diagram of stream and ditch <br /> <br /> <br />systems will be included. This task will be coordinated with <br /> <br /> <br />similar task in the San Miguel Project Study. <br /> <br />8. Develop Plan of Operations for Enlarged Reservoir - Planned <br /> <br /> <br />delivery schedules will be dependent on working agreements <br /> <br /> <br />developed by ditch companies. Report will show monthly <br /> <br /> <br />reservoir operation for a series of years in conjunction wit'h <br /> <br /> <br />other existing facilities. The probable rate of sedimentation <br /> <br /> <br />will be detrecined. <br /> <br />9. <br /> <br />Provide Data Regarding <br />watersheds is known to be <br />analysis. <br /> <br />Water Quality Water from high <br />of high quality - USBR has reports of <br /> <br />;' Chapter V - Plan of Development <br /> <br />/ <br /> <br />10. Perform Geologic Invest:tgations - Since the project involves <br /> <br /> <br />raising an existing dam, it is imperative that sufficient <br /> <br /> <br />information be obtained to provide tentative approval of <br /> <br /> <br />proposed construction methods from State Engineer's office. <br /> <br /> <br />Proposed fielc work will include drilling three core holes into <br /> <br /> <br />bedrock, three auger holes, and six test pits. A geologic map <br /> <br /> <br />and report relating to the suitability of the existing dam as a <br /> <br /> <br />foundation fer the enlargement will be included in this task. <br /> <br /> <br />The report will include geolgoic cross-sections of the dam and <br /> <br /> <br />reservoir basin. Refer to the map in the back pocket for <br /> <br /> <br />details of proposed exploration. <br /> <br />-4- <br /> <br />
