15 feet in the mountainous upper reaches. The oreek flows south- ward from a preoipitous canyon in the Monument area through the transitional foothills to the high plains, joining Fountain Creek at Colorado Springs. The sparse vegetation covering the land is typical of Colorado foothill regions. South of Colorado Springs, the watershed west of Fountain Creek is in the Frontal Range foothills while the eastern portion is primarily high plains. The rolling high plains terrain is rough, broken, and sparsely vegetated. On either side of the flood plain, the vegetation is sparse and typical of the semi-arid high plains--predominantly sage brush, oaotus, and native grass. The flood plain is comprised of narrow-strip irrigated farms, clumps of oottonwood trees, salt oedar, and other thiok undergrowth. The Fountain Creek valley varies from a few hundred feet to 2,000 feet in width within the study reaoh. Fountain Creek is perennial except for a few days during the summer when irrigation and munioipal demands equal or exceed the low summer flows. Some irrigation-return flows are experienced in the plains seotor of the creek. Irrigation and munioipal waters originate for the most part in the west-bank mountain tributaries. Few, if any, of the ,east-bank plains tributaries are perennial. The damaging floods at Pueblo on fountain Creek normally originate south of Colorado Springs on the main stem and tributaries. The long, narrow main stem and tributary watersheds are oonduoive to fast rises and high peak flows of short duration in this reaoh. On the east bank, the tributaries of primary ooncern are Jimmy Camp, Sand, and Williams Creeks; on the west bank, they are Little Fountain Creek, Young Hollow and Steele Hollow. The streambed elevations within the study reach vary from 4,365.6 feet at the mouth of Fountain Creek to 5,152.1 feet at the north Pueblo County line. The channel slopes uniformly 12
