'l . .. 000701 AGENDA Black Canyon Technical Meeting June 26,2001 9:00 - 9:50 am COMMITTEE MISSION: Evaluate basis for the NPS Black Canyon water right filing and its potential impacts on the Aspinall unit and on the streamflows and existing water rights in the Gunnison River basin using the RiverWare and StateMod models 1. Elect chair 2. Specify goals and objectives of technical committee . Will this committee determine the appropriate issues to discuss, or will it be fed specific questions by the NPS, by the larger Fed/State policy discussion group, or eventually by the entire negotiation team(s)? · To whom will the information derived by this committee be given? 3. Timeline · How soon do specific questions need to be answered? · What is the NPS timeline and decision-making process and how will this fit in? 4. Models (RiverWare and StateMod) 4a. General discussion · Role . Capabilities . Features · Limitations · Current status AS TIME ALLOWS... (may have to start here at July meeting) 4b. Detailed discussion of data/policy information needed by USBR for their RiverWare model 4c. Detailed discussion of data/policy information needed by DNR for their StateMod model · CWCB will update their model to include new "variable efficiency" feature · CWCB will update their model to include 1998 - 2000 data This updated general model of the Gunnison basin will be available to the public. Specific modeling of the NPS water right will also require: · Determination (probably by Gunnison PBO group?) of "current" and "future" water depletion scenarios to be modeled · CWCB confers with USFWS to correctly model final flow recommendations · Conversion of the formula in the NPS claim to an instream flow demand
