<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 FIS' were used for this report. <br /> <br />2.0 <br /> <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. <br /> <br />TABLE I <br />GAGE DATA <br /> <br />rx~ml.g(qll~llpmQ$~y~~Ili!~9N';~9~iI.) <br /> <br /> <br />.-.-,-,'-:-,'...........:.....-...:.:.-,:.-.:.:..,.:.,.-.,".:.,.,.:.:.:.-.:..:,-.-.:..:.:.-,-,-.-.:,-.-.:.:...-,:.:.' <br />))GAGElD, <br />.,--,...,.,-,......,-.....-..-....-..-.-,'.-.-..-,-...,-...-,....-...-.....-,...,......-....,..:..,._'_.-.,.. <br />...~~;t'mpg;9Q):'l:9;tmpl$).. <br /> <br />09247600 <br />402815, 1073649 <br /> <br />09251000 <br />403010, 1080145 <br /> <br />09260050 <br />402708, 1083128 <br /> <br />YAMPA RIVER 10 <br />BELOW CRAIG <br /> <br />YAMPA RIVER AT 78 <br />MA YBELL <br /> <br />1750 <br /> <br />3410 <br /> <br />09249750 <br />402614, 1073850 <br /> <br />09260000 <br />403250, 1082525 <br /> <br />YAMPA RIVER AT 10 <br />DEERLODGE <br />PARK <br /> <br />WILLIAMS FORK 10 <br />RIVER <br /> <br />LITILE SNAKE 74 <br />RIVER (LILLY) <br /> <br />7660 <br /> <br />419 <br /> <br />3730 <br /> <br />2 <br /> <br />3 <br />
