11. Update on the Colorado Ri~~er Basin Mediation process. CBRT members include Rick <br />Sackbauer, Lurline Curran. Stan Lazier. Dick Proctor, and Tom Long. The goal is to facilitate <br />better conummication and cooperation between water providers on both sides of the Continental <br />Divide. They met in Ke~~stone for 2 days in Tune, and will meet again iii August with facilitator <br />,Tolui Bickerman. <br />12. Update on Water A~~ailabilit~~ Study (WAS) mandated h~ SB U7-122 - Da~~e Merritt. <br />a. Senate Bi1107-122. the CWCB annual appropriations bill, allocated $00.000 to shidv the <br />eltent of water available for additional de~~°elopment in Colorado. The Colorado River Basin <br />is the only basin in the state ~~-•ith surplus water. Bti~ contrast. the Rio Grande. South Platte <br /><md Arkansas Basinsare over-appropriated and must re-allocate elistilrg water supplies. The <br />study will attempt to answer how much water is available to meet Colorado's current and <br />fiiture needs. <br />b. The goal is to determine how much water can be safely developed, and to determine where <br />water is available. <br />c. Bashi roundtables are asked to contribute input based on the consumptive, non-consumptive, <br />quid energy needs analti~ses. Once the IBCC has approved the scope of the shid~-, basin <br />roundtables will also have an opportunity-~ to c~~nunent on the scope of work. <br />d. The study- has 3 phases: <br />Phase 1 Deternine available supplies based on historic data, and alternate data. <br /> .=llte~°i~crte dntn is the estimated fiiture supply based on stochastic (i. e.. <br /> probability~j modeling. Water gages have been available in Colorado for about <br /> 100 ve<~rs, and tree-ring data is available for X00 years: see the August 2006 <br /> CBRT minutes for a discussion of tree ring drought anah~sis be Connie <br /> Woodhouse. PhD. Based on this historic data. alternate data to predict fiiture <br /> supplies will be created. <br />Phase 2 Evaluate climate change on hy-drology-. What range of change in 1>istorical <br /> supplies can we elpect from climate change'? <br />Phase 3 Compare current and fiiture demands to the range of estimated water supplti~ that <br /> ~3°as deternined in Phase 1 and 2. <br />e. Phase III will develop up to 10 scenarios of fiiture water demands considering: <br />i. Climate change effects <br />ii. Energ~~ (oil shale) development <br />iii. Other conditional water right development <br />iv. Increased municipal and industrial demands <br />v. Other consumptive demands (i.e. changes nI irrigated acreage) <br />~°i.
