Although portions of the Colorado watershed are located in several other <br />Colorado counties, the entire study reach lies in Mesa and Garfield Counties in west-central <br />Colorado. (see Figure 2) <br /> <br />2.2 Study Reach <br /> <br />The focus of this study on the Colorado River mainstem is from the Highway 13 bridge at Rifle, <br />Colorado (approximately 93 miles upstream of the Utah stateline) downstream to the stateline. <br />At the upstream limit of the study the stream elevation is approximately 5300 feet and at the <br />downstream limit of the study the stream elevation is approximately 4330 feet. The study reach <br />contains four USGS gages. One is located upstream of DeBeque, one is upstream of Cameo, one <br />is at Palisade, and one is located upstream of the Utah state line. There is also a gage at <br />Glenwood Springs, approximately 25 miles above the upstream study limit. Tributary gages are <br />located on Plateau Creek near the confluence with the Colorado River and on the Gunnison River <br />at Whitewater, Colorado. Information for the four gages within the study reach, the gage at <br />Glenwood Springs, and the gages on tributary streams is listed in Table 1. <br /> <br />TABLE 1 <br />GAGE DATA <br /> <br /> <br />09085100 GLENWOOD SPGS 29 6013 <br />393338,1071759 (2 MI E) <br />09093700 DEBEQUE (3.8 MI 29 7370 <br />392145,1080907 NE) <br />09095500 CAMEO (7 MI NE) 62 8050 <br />391420,1081600 <br />09106150 PALISADE (.25 MI 5 8753 <br />390555,1082116 S) <br />09163500 UTAH STATE 44 17843 <br />390745,1090136 LINE (1.5 MI U/S) <br /> <br />3 <br />
