<br />Moffat Couaty. The two FIS' are more recent than the Corps study and include minor revisions
<br />to the information in the Corps study, so the FlS' were used for this report.

<br />STUDY AREA
<br />
<br />2.1 Location
<br />
<br />The reports referenced above are available at the office of the Colorado Water C,o_nservation
<br />Board, at the Federal Emergency Management Agency (Region VII), at the City of Craig, and
<br />at Moffat County.
<br />
<br />The study reach of the Yampa River extends from Craig downstream to the upstream end of
<br />Dinosaur National Monument. Although portions of the Yampa watershed are located in other
<br />Colorado counties, and even in Wyoming, the entire study reach lies in Moffat County in
<br />northwestem Colorado (see Figure 2).
<br />
<br />2.2 Study Reach
<br />
<br />The focus of this study on the Yampa River is from the downstream liinit of the FEMA detailed
<br />study for Craig, Colorado (57 miles upstream of the Deerlodge Park gage) downstream to the
<br />upstream limit of Dinosaur National Monument (1 mile upstream of the Deerlodge Park gage).
<br />At the upstream limit of the study (Craig) the stream elevation is approximately 6150 feet and
<br />at the downstream limit of the study the stream elevation is approximately 5600 feet. The study
<br />reach contains three USGS gages. One gage is located at the upstream limit of the study, one
<br />at the downstream limit, and one is located approximately in the middle of the reach.
<br />Information for those three gages, as well as for two gages on tributary streams, is listed in Table
<br />1.
