Preface

The Colorado Water Conservation Board has prepared a Floodplain Information Report for the
Colorado River mainstem subbasin of the Upper Colorado River Basin. The Board has also
prepared similar reports for three other subbasins of the Upper Colorado River Basin: the Yampa
River (from Craig, Colorado, downstream to Dinosaur National Monument); the White River
(from Rio Blanco Lake downstream. to the Utah stateline); and the Gunnison River (from Delta,
Colorado, downstream to its mouth). Figure 1 on the next page shows the four stream reaches
of critical habitat in the Upper Colorado River Basin. Each of these reports has been prepared
to provide local officials with the most current approximate floodplain information, to assist them
in their local floodplain management programs.

This Floodplain Information Report presents the results of a study for the delineation of the 50-
year and 100-year floodplains on the reach of the Colorado River mainstem from Rifle, Colorado,
downstream to the Utah stateline. It is intended to assist the City of Rifle, the Town of
Parachute, Garfield County, the Town of DeBeque, the Town of Palisade, the City of Grand
Junction, the City of Fruita and Mesa County.

While the report has been prepared with local floodplain management needs in mind, the CWCB
is aware that this reach of the Colorado River mainstem has been designated as critical habitat
for endangered fish by the U.s. Fish and Wildlife Service (Service). The Service may choose
to utilize some of the information in this report for Endangered Species Act purposes, but the
CWCB neither endorses nor objects to such utilization. The CWCB has endorsed this report for
floodplain management purposes only.
