<br />2.0 STUDY AREA
<br />
<br />2.1 Location
<br />
<br />The study reach of the White River includes the entire reach that was designated as "critical
<br />habitat" for the endangered fish species. Although portions of the White River ate located in
<br />other Colorado counties, the entire study reach lies in Rio Blanco County in northwestern
<br />Colorado (see Figure 2).
<br />
<br />2.2 Studv Reach
<br />
<br />The focus of this study on the White River is from downstream of Rio Blanco Lake (53.5 miles
<br />upstream of the Utah stateline) to the stateline (15 miles downstream of Rangely). At the
<br />upstream limit of the study (Rio Blanco Lake) the stream elevation is approximately 5720 feet
<br />and at the downstream limit of the study the stream elevation is approximately 5040 feet. The
<br />study reach contains one USGS gage on the mainstem which is located 16.5 miles upstream of
<br />Rangely, approximately in the middle of the reach. Information for this gage, and for another
<br />gage on the. White River at Meeker, about 20 miles above the upstream study limit, as well as
<br />for two gages on tributary streams, is listed in Table 1.
