<br />SECTION II <br /> <br />THE STUDY AREA <br /> <br />The pilot study area of the Big Dry Creek drainage basin is presently <br />a series of mostly agricultural sub-basins lyin!! in Townships I and 2 <br />South, Ranges 67, 68, 69, and 70 West, of the 6th Principal Meridlan*. <br />The total tributary area of the basins is 86.3 square miles. The eleva- <br />tions range from 5,040 feet at County line Road to 6,,500 at the western <br />divide of Big Dry Creek. <br /> <br />The individual drainage basins and design points are as follows, <br />and are shown On Sheet 1 of Volume 2. <br /> <br />Basin <br /> <br />From <br /> <br />To <br /> <br />A <br />B <br />C <br />o <br />E <br />F <br />G <br />H <br /> <br />Divide <br />Divide <br /> <br />Grel~t Western Reservo! r <br /> <br />Stand I ey lake <br /> <br />Great Western Reservoi r <br /> <br />Tu rnp I ke <br />Turnpike <br />U.
