high plains. The rolling high plains terrain is rough, broken, and sparsely vegetated. The sparse vegetation is typical of the semiarid high plains--predominantly brush, cactus and native grasses. The flood plain is comprised of narrow-strip irrigated farms, clumps of cottonwood trees, salt cedar, and other thick undergrowth. . . Camp Creek originates in the Pike National Forest northwest of Colorado Springs, approximately 5 miles northwest of Glen Eyrie where it turns south, continues for approximately 3 miles, enters Colorado Springs and joins Fountain Creek near 30th Street. The creek flows in a concrete-lined channel in residential areas. Cottonwood Creek, an east bank tributary of Monument Creek, origi- nates near Black Forest north of Colorado Springs. It flows south- westerly through northern Colorado Springs, passes under the Atchison, Topeka, and Santa Fe Railway and Interstate Highway 25, and joins Monument Creek. The stream along most of its course is deeply eroded into rock outcroppings and in the lower reach is lined with willows. Within Colorado Springs, Cottonwood Creek flows in a sand-bottom, riprap-sided channel. Douglas Creek (North and South) drains an area in and adjacent to northwestern Colorado Springs. The stream flows southeasterly for approximately 8 miles to join Monument Creek near the Templeton Gap Floodway outlet. Lower portions of Douglas Creeks North and South have been channelized into concrete-lined drainage structures. Dry Creek, North Channel Dry Creek, North Fork Dry Creek, South Valley Dry Creek, and Big Valley, collectively, drain the Dry Creek Basin. If' The Dry Creek Basin is bounded on the west by the Front Range of the Rocky Mountains, on the south and north by ridges, and on the east by Monument Creek. It slopes from west to east toward Monument Creek, rising from an elevation of 6,250 feet to elevation 9,250 feet. The western portion of the basin is heavily forested, mountainous terrain, drained by three major tributaries of Dry Creek. These tributaries are steep, well defined ravines which come to a confluence west of the Sisters of Mount Saint Francis Convent. The central portion of the basin is characterized by gently rolling wide valleys, separated by foothill ridges and mesas. Through the central portion of the basin, Dry Creek is poorly defined and flows through broad, gently sloping meadows. The eastern portion of the basin is fully developed, and Dry Creek flows through well defined and eroded channels as well as greenbelt areas (Reference 2). Dry Creek has been channelized from approximately 1,500 feet downstream of Dairy Ranch Road to a point approximately 500 feet upstream of Dancing Horse Road. FOr the most part, flow in Dry Creek and its tributaries is intermittent. 5
