Colorado Division of Water Resojlrces (CDWR)
South Platte Decision SUPPOtt System (SPDSS) - Year 2
Part of Colorado Decision Sllppott System (CDSS)
Multiple
South Platte and North Platt~
South Platte and North Platt~ Rivers including all tributaries and major

Project Name:
Project Type:
Counties:
Drainage Basin:
Water Source:
groundwater aquifers,
Amount Requested in FY2002-2003: $ 2,000,000
Estimated Total Project Cost: $ 15,000,000

The CWCB acting through their Water Supply Protection Section and in coordination with the CDWR is
nearing completion ofthe feasibility study that will identify the purposes for, uses of, users, model
components, data bases and data requirements, costs and schedule for developing SPDSS, The
Feasibility Study will identify a preferred alternative that meets water user needs and has the best
probability of success, The preferred alternative bec()mes,the "road map" that will guide SPDSS
development over the next several years, This request is for funding of year 2 data collection and
development activities for SPDSS without which mOllel d~velopment can not proceed in an efficient _
manner, The Feasibility Study well be finalized prior to any expenditure of year 2 funds, ..

The overall purpose of SPDSS is to provide state officials and water users with a creditable and efficient
set of tools with which to plan, develop and manage the water resources in the North and South Platte
River Basins, Based on the Colorado River Decision Support System (completed) and the Rio Grande
Decision Support System (nearing completion), SPDSS is envisioned to be a data centered system and
include surface and groundwater models, a consumptive I.\se model, an overall water budget model, and
water right administration and analytical tools, The projept when completed will improve water
management and development opportunities throughout the basins, SPDSS well allow better
coordination between: ground water recharge and storageiprojects, water right and South Platte River
Compact administration, and the identification of opportunities to benefit biological species of concern in
Colorado and participation in the Platte River Cooperative Agreement. These data and tools are of
statewide interest and should be developed in a timely fa~hion, An Advisory Committee has been
established to help guide both the Feasibility Study and df:velopment of SPDSS, Funding will allow the
CWCB and CDWR to continue collecting the necessary <lata prior to model development. The final
Feasibility Study will be available in October 2001, SPDSS development is envisioned to take
approximately 6 or 7 years to complete and require approximately $2,000,000 annually,
