Permeability is moderate and the available water capacity is moderate. The surface runoff is slow and the erosion hazard is slight. SOIL CAPABILITY -- Non-brig. - IIIw, Irrig. IIIw. RANGE SITE -- Sandy Meadow. 29 FLUVAQUENTS Fluvaquents are deep, somewhat poorly drained soils formed in recent alluvial deposits bordering the South Platte River channel. They are nearly level. The area is dissected by old river channels and by intermittent streams.

These soils have a fluctuating water table ranging from 10 to 60 inches during winter and summer months. SOIL CAPABILITY -- Irrig. - VIw. 39 HAYFORD SILTY CLAY LOAM This is a deep, somewhat poorly drained soil with a silty clay loam surface texture and a heavy silty clay loam subsurface texture. Permeability is slow and available water capacity is moderate. Surface runoff is slow and erosion hazard is slight. SOIL CAPABILITY -- Non-Irrig. - IIIw, Irrig. - IIIw. RANGE SITE -- Salt Meadow. 128 WESTPLAIN-ALDA COMPLEX These are deep, somewhat poorly drained soils. The surface texture is calcareous silty clay loam to loam and the subsurface texture is a very gravelly clay loam. The permeability is slow to moderate and the available water capacity is moderate. The surface runoff is slow and the erosion hazard is slight. There is a fluctuating water table present. SOIL CAPABILITY -- Non-Irrig. - VIw, Irrig. - IVw.
