<br />003083 <br /> <br />CRDSS Scoping Primer <br />For review prior to June 22-23,1995 CRDSS Scoping Sessions <br /> <br />Scoping Meeting Objective: <br />To provide an initial forum for DWR and CWCB staff to express their needs and goals <br />for CRDSS development in 1996-1998 such that those expressions can be considered in <br />the scope being prepared this summer and fall by state CRDSS representatives. The <br />work product of this scoping meeting is a prioritized list of potential year 3 activities. <br />Further scoping and budgeting of the identified activities will occur before subsequent <br />scoping sessions are held. <br /> <br />CRDSS Project Objective: <br />To provide the capability to develop credible information on which to base informed <br />decisions concerning management of Colorado River water resources (planning, <br />administrative and operational issues). The Project focuses on supporting decision <br />making and planning in the following primary areas: <br />· Interstate Compact Policy including evaluation of alternative reservoir and river <br />operating policies, determination of available water for development, and <br />maximization of Colorado's apportionment. An important part of the <br />determination of available water for development is the refinement of estimated <br />consumptive use (depletions) in Colorado. <br />· Water Resource Planning, including development and use of a water resource <br />planning model (i.e. new projects, water exchanges, operating plans) and <br />evaluation of impacts of instream flow appropriations (e.g. endangered fish flow, <br />minimum flows). <br />· Water Rights Administration, including optimization of water rights <br />administration, on-line sharing of information between water users, and <br />administration of water rights within compact allocations (i.e. alternative <br />strategies of administration which will enable maximum use of available <br />reservoirs). <br /> <br />CRDSS Project Status: <br />The first year of development was completed in early 1995 with the development of <br />prototype databases and planning models, principally for the Gunnison River Basin, <br />Water Division 4. Starting March 1, work continued on completing the historical <br />databases and planning models for the Colorado River drainages within Colorado. The <br />schedule calls for the following to be completed by May 31, 1996. <br />· Historical time series databases for streamflow, ditch diversions, reservoir <br />contents, and climate data with easy to use database browser and analysis tools. <br />· Water right tabulation database with easy to use browser and report generator. <br />· Maps of irrigated acreage, land use, elevation, rainfall, evaporation, diversion, <br />steamflow and reservoir structure locations, water districts, counties, etc. in a map <br /> <br />May 31, 1995 <br /> <br />1 <br />
