Historic Data Availability

A number of streamflow gaging stations are maintained by the U.S. Geological Survey within the
Yampa, Little Snake, and Green River basins. The four principle gages for this analysis are shown in
Figure 4.1; these are the Yampa River near Maybell, Little Snake River near Lily, Yampa River at
Deerlodge Park, and Green River near Jensen stations. Since the Maybell and Lily gages are located near
the terminus of their respective sub-basins, they provide a good measure of the streamflow and sediment
yield from each sub-basin. Other stations and miscellaneous sites within each sub-basin provide
information concerning the variability of streamflow and sediment. However, the majority of long term
data has been collected at the above four sites, and these sites have been key locations in previous sediment
studies. Table 4.1 shows periods of continuous streamflow and suspended sediment record at the four
principle gaging stations.
