The Little <br />Snake heads on the Continental Divide, runs in a westerly <br />direction, crosses the Colorado-Wyoming state line a number <br />of times and discharges into the Yampa River in Colorado. <br />The drainage basin includes parts of Moffat and Routt <br />Counties. <br /> <br />The watershed is all above and elevation of 5,650 <br /> <br /> <br />feet with approximately 60 percent above an elevation of <br /> <br /> <br />7,000 feet. The higher mountain peaks along the Contin- <br /> <br /> <br />ental Divide extend to elevations in excess of 12,000 feet. <br /> <br />Watershed Runoff <br />The average annual historic runoff for the Little <br />Snake River at the U. S. Geological Survey Lily gaging <br />station for the report period of 1943-1960 was 379,300 acre <br />feet. Of this amount, it is estimated that 46.8 percent, <br />or 177,500 acre feet, originated as runoff on watershed <br />located in Colorado and 53.2 percent, or 201,800 acre feet, <br />originated as runoff from watershed in Wyoming. The May - <br />July runoff from the melting of the accumulated winter snow <br />accounts for 74 percent of the annual runoff. The following <br />table gives the annual runoff of the subbasin for each year <br /> <br />12 <br /> <br />
