CDSS_2002_Annual_Report

• Title: CDSS 2002 Annual Report
• Description: A recap of the work done for and by the Colorado Decision Support Systems.
• Decision Support - Doc Type: Publication
• Date: 1/1/2003
• DSS: All
• Basin: Statewide
• Prepared By: CWCB

This past year's emphasis has been on the
completion of the RGDSS, beginning the data
collection and model building for the SPDSS, use of
the water resource planning tools, updating the
irrigated acreage for the western slope, and future
management of the CDSS including long-term
operation and maintenance of the system.
CDSS FY 01-02 & 02-03 Legislative
Actions and Decision Items
2002 saw the passage of two Decision Items related
to the CDSS. These decision items, approved by the
legislature, created two new positions within the
CWCB. One, the DSS Coordinator, will oversee all
aspects of the entire DSS system, and it's
implementation, operation and maintenance. The
other, a GIS technician position, will aid the CWCB
in creating maps and other tools using data supplied
by the DSS.
The following table presents the legislative history
of CDSS funding for the past two years. As
presented, the Colorado River and Rio Grande
systems were developed at an approximate cost of
$8 million and $5 million dollars respectively.
Future O&M costs required to provide statewide
coverage are expected to vary based on basin
complexity, although the modular design and
economies of scale will control costs and maintain
quality.

Statewide
The database was refreshed to include data through
the year 2001. Data that was refreshed statewide
includes stream flow, water rights, diversions, well
permits, and climate data (precipitation,
temperature, evaporation and wind). This data is
available on CD and via the Web. The Web
interface was upgraded to be consistent with current
CWCB and DWR standards.
Rio Grande Basin
In 2002 most of the components of the RGDSS
were completed or near completion. The following
list summarizes the status of the RGDSS
components:
• The Consumptive Use and Water Budget
contract is 100% complete.
• The Surface Water contract is 90% complete.
Major tasks remaining include updating
modeling and documentation with revised
Unit Response Functions from the final
ground water model.
• The Ground Water contract is close to
completion. Extensive work was performed
this year on the steady state, average monthly
and monthly transient groundwater models.
Draft versions of these models are complete,
with the final versions nearing completion.
Additional work completed includes and
update of the hydrogeologic database and
modeling with new aquifer parameter values.
• Both the Relational System Integration and the
Spatial System Integration contracts are close
to complete.
