The only major directional change of flow was found <br /> <br />in Sub-basin 23 on Dublin Drive, At this point, the primary <br /> <br />channel has been partially blocked and the flow follows an ancient <br /> <br />bed of Cottonwood Creek to the southwE!st, <br /> <br />Drainage throughout the basin is <br /> <br />basically dendritk and uncomplicated, except in the older develop- <br /> <br />ments around Academy Boulevard. The flow is generally collected <br /> <br />in the main stream via a number of small tributaries and flows <br /> <br />almost directly to Monument Creek. Nearly all of the tributaries <br /> <br />are normally "intermittant" streams and do not carry water except <br /> <br />after storms or during the snowmelt period, Erosion has cut much <br /> <br />of the Cottonwood Creek deeply, but has deposited considerable <br /> <br />amounts of bed sand at points of low grade. Deep erosion of this <br /> <br />type is normal to the Dawson Formation, and is not necessarily <br /> <br />a result of large amounts of water. <br /> <br />-8- <br />
