<br /> <br />. <br /> <br />Revised Draft <br /> <br />7/17/2001 <br /> <br />· Automated call notification so that water users can efficiently manage their resources <br /> <br />· Improved access to real-time streamflow and diversion data to assist with <br />administration <br />· Development of improved tools and procedures to allow direct entry of data by users <br />into a provisional real-time database to facilitate river administration <br /> <br />· Better access to historic river call, augmentation plan, substitute supply plan and <br />transfer decree data <br /> <br />· Improved ability to perform bulk analysis of real-time or historic data to help <br />summarize the effects of current conditions or administrative decisions <br /> <br />· Access to animation tools for presentation and visualization of real-time and historic <br />satellite and Water Information Sheet data <br /> <br />Planning Tools <br /> <br />The development of planning tools for the SPDSS fulfills many of the needs of the CWCB <br />and DWR as well as Colorado water users who require tools and models they can trust to <br />develop predictions and determine outcomes of particular events. Alternative 2 will provide <br />better tools and models for: <br /> <br />· Evaluating the success of Platte River species of concern efforts. <br /> <br />. <br /> <br />· Improving the applicability of streamflow depletion factors for groundwater analysis <br />in the Lower South Platte Alluvium Region <br /> <br />· Determining the effects of groundwater pumping <br /> <br />· Providing dataset quaJity assurance/quality control (QNQC) <br /> <br />The following planning tools and models are included in Alternative 2: <br /> <br />. <br /> <br />· A basin-wide water resource planning model (StateMod) that operates on a daily time <br />step and includes 100 percent of the basin's consumptive use. This sustainable tool <br />will be available to water users the CWCB and DWR for planning purposes, <br /> <br />· An enhanced groundwater model for the Denver Basin and Overlying Alluvium <br />Region that operates on a monthly time step, includes up to eleven layers and utilizes <br />a one-quarter to one-square mile grid. This enhanced model will facilitate better <br />quantitative understanding of flows between the alluvium and the underlying Denver <br />Basin aquifers, and among the Denver Basin aquifers, This enhanced groundwater <br />model will allow unique treatment of each Denver Basin aquifer, confining layer and <br />the overlying alluvium. Estimates of well pumping will be refined significantly <br />compared to the existing Denver Basin model. <br /> <br />· A groundwater flow model of the Lower South Platte Alluvium Region (from the <br />Stateline upstream to approximately Weldona) that operates on a monthly time step. <br />There is no existing groundwater model for this region. Consequently, water users, <br /> <br />p:\data\gen\spdss\drafts for core group submittal\exec_summary_draftdoc <br />July 17,2001 <br /> <br />E-6 <br />
