Scope of Work <br />Upper Mountain Counties Water Needs Assessments <br />Task 5- Long Term Sustainability of the Aquifer Systems will be Evaluated <br />5.1 Ground water level dc~ta will be evaluated for any lorig ter~i trends <br />The available ground water level data that nlay be available will be acquired to <br />deternune if any water level trends are apparent. The infornlation fronl Jefferson <br />County staff, Roy Laws, will be acquired along with any ofller data such as fronl <br />DWR and the USGS. <br />5.2 Areas witlr known aquifer water suppl~ concerns will be ideritified <br />T11e cowlties, towns, and water providers will be surveyed for lalown aquifer water <br />supply concerns such as water quantity, water quality, infrastructure, or water level <br />concerns. This infornlation will l~e evaluated for inlpact on t11e long ternl <br />sustainability of the aquifer systems. <br />5.3 Lo~ig terni pirysical sustainability of varioiss nquifer systems will be evnluc~ted <br />T11e estiinated aiulual depletions for various aquifer systems based on water <br />demand estimates for various periods up to 2050 will be compared with <br />estimates of long term aiulual recharge. Areas where aquifer levels may be <br />expected to decline will be identified and tllese areas mapped using a GIS <br />overlay. Areas with aquifers in a sustainable condition will be also identified <br />and these areas mapped using a GIS overlay. Sustainability is defined for this <br />study as the ability to use the aquifer systeins to meet current and future needs <br />without mining of the aquifers and without significant degradation of the <br />quality of the ground water. <br />Task 5 Assuyriptions <br />^ One ineetuzg with Poy Laws, DWP, and USGS to acquire water level data. <br />^ One phone uzterview with each county, town, and ~nTater provider to discuss water <br />supply concerns will be conducted witll approximately 30 entities. <br />Task 5 Deliverables <br />^ Areas with known ground water level declines will be shown on GIS maps. <br />^ Areas with known aquifer supply concerns will be shown on GIS nlaps. <br />^ GIS Maps showing aquifer systems with long ternl sustainable conditions and <br />aquifer systems with long term unsustaulable conditions. <br />Task 6- Water Needs for Future Recreation and Tourism Demands will be <br />Estimated <br />T11e counties will be surveyed for possible new recreation or tourisnl related water <br />demands (consunlptive) that nlay develop u1 the future such as new ski areas or snow <br />boarding areas. The water supply for these possible new projects will be assunled to <br />be provided by the developer of the project and this task is to identify associated <br />water denlands that may occur that would inlpact tlle surrowlding area. <br />C:\Documents and Settings\rowannc\Desktop\To File Back\UMGSOW-rv4.doc <br />
