The Colorado River Decision Support System (CRDSS) is a collection of computerized
databases and models designed to aid management of the water resources of the
tributaries of the Colorado River Basin in Colorado. The purpose of the system is to
help Colorado agencies make informed decisions on Colorado River issues. The
Colorado Department of Natural Resources retained Boyle Engineering to aid in the
design, testing, and implementation of the CRDSS during its third phase of
development.
Boyle enhanced the state's existing water resources planning models for the Yampa
River Basin, the Colorado River Basin, the Gunnison River Basin, and the San Juan -
Dolores River Basins. The enhancements involved including 100 percent of basin
consumptive use in the models by aggregating demands, diversions, and water rights
of numerous small users; adding forecasting capabilities for flood control reservoirs;
calibrating the models; and updating and completing the documentation. Boyle also
provided critique of the DSS components and documentation from the user
perspective.
Under Phase Illb of the CRDSS project, Boyle is assisting in design and testing of the
Division 5 Worksheet component of the water rights administrative tool. The
worksheet is a workbook of interrelated
spreadsheets showing reservoir
operations and accounting, which will
aid the Division Engineer in setting
calls in Division 5.
Boyle is currently extending the
historical data sets for the water
resources models, and managing
development of a stochastic data set.
The historical data set extension
involves data collection, as well as
development of new DSS components
for filling missing data.

The area shaded green was developed as part ofihe Colorado River Decision Support
System (CRDSS) ,which includes Diision 4 (Gunnison River Basin), CIMsion 5
(Colorado Main Stem), DM.ion 6 (Whhe and Yampa Rivers), and Dm.wo 7 (San Juan
and tributaries).
The area shaded blue was developed as part of the Rio Grande Decision Support
System (RGDSS) , which includes DMsion 3 (Rio Grande Basin).
The area shaded red is under development as pan ofihe South plane Decision

the fell of 2001.

The area shaded grey is envisioned for fuhn, development and includes Water Dishicd's
49 and 65 of Division 1 (Republican River).
The CWCB retained Boyle Engineering in 1999 to aid in
the design, testing, and implementation of the CRDSS
during its third phase of development.
