~. 64 - Loveland clay loam, 0 to 1 percent slopes IIIw-1 Irrigated Vw-1 Oryland This soil is found on low terraces and flood plains, and is underlain by sand and gravel at depths of 20 to 40 inches. The Loveland series consists of deep, somewhat poorly drained soils that were formed in material weathered from alluvium. The native vegetation is mainly blue grams, bluegrass, and sedges. Mean annual precipitation ranges from 13 to 15 inches, mean annual air temperature ranges from 48 to 50 degrees F, and the frost-free period ranges fron 135 to 150 days. In a typical soil profile, the surface layer is mottled dark grayish brown or grayish brown clay loam about 15 inches thick. The underlying material is 17 inches of grayish brown clay loam over sand, gravel, and cobbles. Included with this soil in mapping are a few small areas of sails that are more sloping, and small areas of soils in which gravel is at a depth of 40 to 60 inches. Permeability is moderately slow above a depth of 32 inches and very rapid below that depth. The available water capacity is medium to high. Reaction is mildly alkaline above a depth of about 8 inches and moderately alkaline below that depth. Runoff is slow, and the hazard of water erosion is slight. If irrigated, this soil is suited to barley and pasture. Under dryland management it is well suited to pasture and native grasses. This unit is a Wet Meadow range site. 92 - Riverwash VIIIw-1 Oryland This unit is highly variable, mixed water-washed sand and gravel deposits, commonly found next to stream channels. These areas are flooded each year, generally in the spring or summer. In some places willow trees protect the sail from erosion along the stream banks. Forage production is low and there is little grazing value. These areas provide shelter and habitat for wildlife. This unit is not assigned a range site. (2l
