2005 CDSS Legislative Actions, Decision
Items, and Funding
SPDSS Legislative History
2005 saw the passage of the CWCB Construction
Fund Bill, Senate Bill OS-209, which included
additional funding for SPDSS. The additional $1.5
million will be used to implement Phase 4 of
SPDSS.

2005 Accomplishments
Statewide
CDSS had a successful year in 2005, completing a
vast majority of the goals stated in last year's annual
report.
Most of the western slope river basin models were
updated, using the latest versions of StateDMl and
StateMod. New models and documentation are
available on our website for the Gunnison, Yampa,
San Juan and Rio Grande basins.
With the help of western slope water commissioners,
ground truth data was collected for crops this
summer across the entire western slope. This data
will be used in 2006 in the irrigated lands data
refresh effort.
Implementation of the Instream Flow DSS (ISFDSS)
was hampered by contracting issues, but work got
underway mid-year, and is expected to be completed
in early 2006.
In addition to the stated goals, 2005 saw the
implementation of a remodeled CDSS website,
which utilizes a database backbone to serve up data
and information to the user. The CDSS website was
completely redone to make the site more intuitive
and more searchable. We are quite pleased with the
way the site
turned out and
how much more
efficient and
maintainable the
site has become.
Brown and
Caldwell, one of
our SPDSS
contractors, with
the help of DWR
staff, did the
work.
The DSS Internet Map Server (IMS) website also
came online in 2005. This site allows the user to
view all of the available DSS GIS data via a map
server. This site is available through the Map
Viewer link on the CDSS website.
Rio Grande Basin
The RGDSS went from a DSS in progress to a fully
functional DSS that is being used by DWR, as well
as by various entities in the San Luis Valley. The
surface water planning model is in the final stages
of being updated with the modeling period being
extended to 2004, the latest year that complete
hydrologic data is available.
Colorado River Basin
The Gunnison, Yampa and San Juan River Basins
surface water planning models have been updated
for both monthly and daily data sets, which are
available for downloading at the CDSS website.
The Gunnison model is currently being used by
CWCB staff in the analysis involving the
reoperation of Blue Mesa Reservoir, through the
EIS process. The San Juan model is still being used
as part of the analysis of the San Juan River
associated with future water construction projects in
Colorado. Currently, before any CWCB construction loans
can be given, applicants must complete the water supply
component of a feasibility report. The CDSS system allows
Ci~CB staff to quickly and accurately evaluate the feasibility
of future water projects. The net result is less startup cost,
time savings, and a consistent approach to water supply
studies.
