Although portions of the Gunnison watershed are located in other Colorado <br />counties, the entire reach of the Gunnison River study (between Delta and Grand Junction) is <br />divided almost equally between Delta and Mesa Counties in the west-central region of Colorado <br />(see Figure 2). <br /> <br />2.2 Studv Reach <br /> <br />The focus of this study on the Gunnison River is from downstream of Delta (approximately 43 <br />miles upstream of the confluence with the Colorado River at Grand Junction) to the confluence <br />(at Grand Junction). At the upstream limit of the study (Delta) the stream elevation is <br />approximately 4920 feet and at the downstream limit of the study the stream elevation is <br />approximately 4550 feet. The study reach contains two USGS gages. One is located at the <br />upstream limit of the study (at the US Highway 50 bridge in Delta) and one is near the <br />downstream limit of the study at Whitewater, Colorado (at the Highway 141 bridge crossing <br />approximately 9.5 miles upstream of the confluence). Information for those two gage, as well <br />as for one gage on a tributary stream is listed in Table 1. <br /> <br />TABLE I <br />GAGE DATA <br /> <br /> <br />09144250 GUNNISON RIVER AT 19 5628 <br />384501,1080406 DELTA (UIS HWY 50 <br /> BRIDGE) <br />09152500 GUNNISON RIVER 9 79 7928 <br />385900,1082700 MI UlS GRAND <br /> JUNCTION AT <br /> WHITEWATER <br />09149500 UNCOMPAHGRE 57 [115 <br />384431,1080449 RIVER AT DELTA <br /> <br />2 <br />
