Elevation is 6,800 to 11,600 feet. The average annual precipitation is 16 to 18 inches. These soils are of hydrologic soil complex Group D. These soils are shallow to deep and are well drained. They formed in residuum, colluvium, glacial outwash, till, and alluvium derived predominantly from igneous, metamorphic, and sedimentary rocks. The soils are used mainly for woodland, wildlife habitat, livestock grazing, recreation, or rangeland. The vegetation in the upper watersheds of Four-Mile Creek and Mud Gulch is predominantly rangeland with some woodland and numerous outcrop areas.

The flood plains \\ithin the study limits generally contain typical residential and commercial property improvements; such as buildings, yards, fences, streets, recreational vehicles, etc. Vegetation includes orchards, lawns, shrubs, trees, flO\\'ers, and hay fields as part of the landscape. There are some \dllows and cottoD\mods along those channels ha\ing a sustained water supply. The channel does a considerable amount of meandering and prmides vegetated areas for \\ildlife habitat. The mean annual precipitation for the basins ranges from 12 to 18 inches. A precipitation station, located at an ele\'ation of 5,343 feet near the Warden Penitentiary in Canon City, has a mean annual precipitation of 12.57 inches, of which the greatest m'erage monthly rainfall occurs in August - 1.88 inches. Sno\\fall does occur throughout the "inter period; however, there is no large accumulation. An 7
