Colorado Water Conservation Board '(CWCB) and
Colorado Division of Water Resources (CDWR)
South Platte Decision Support SysteJP. (SPDSS) - Year 2
Part of Colorado Decision Support SYstem (CDSS)
Multiple
South Platte and North Platte
South Platte and North Platte Rivers including all tributaries and major
groundwater aquifers,
Amount Requested in FY2002-2003: $ 2,000,000
Estimated Total Project Cost: $ 14,990,060

The CWCB acting through their Water Supply Protection Sebtion and in coordination with the CDWR
has completed the feasibility study identifying the purposes for, uses of, users, model components, data
bases and data requirements, costs and schedule for developing SPDSS. The Feasibility Study identifies
a preferred alternative that meets water user needs and which has the best probability of success. The
preferred alternative is the "road map" that will guide SPDSS development over the next several years.
This funding request is for year 2 data collection and development activities for SPDSS without which
model development can not proceed in an efficient manner, , e

The overall purpose of SPDSS is to provide state officials aitd 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 use model, an overall water budget model, and
water right administration and analytical tools. The project when completed will improve water
management and development opportunities throughout th~ basins, SPDSS well allow better
coordination between: ground water recharge and storage ~rojects, 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 IAgreement. These data and tools are of
statewide interest and should be developed in a timely fashion. An Advisory Committee has been
established to help guide both the Feasibility Study and the actual development of SPDSS. Funding will
allow the CWCB and CDWR to continue collecting the necessary data prior to model development. The
final Feasibility Study was completed in October 200 I. SPDSS development is envisioned to take
approximately 7 years to complete and require approximately $2,000,000 annually.
