This unit is on flood plains and depressions of <br />stream terraces. Elevation is 5,00 to 8,000 -feet. The <br />mean annual precipitation is 11 to:.IS inches, the average <br />air temperature is 44 to 45 degrees F., and the frost free <br />period is 65 to 65 days. <br />The Fluvaquents soil is very deep and very poorly or <br />poorly drained. It formed in alluvium. The surface-layer <br />is dark grayish brown sandy loam, loam, or clay loam 2 tors <br />inches thick. The underlying material is gray stratified <br />sand, loamy sand, sandy loam, loam, clay loam, or clay. In <br />some places sand or extremely gravelly sand is at a depth of <br />10 to 60 inches. <br />Permeability of the Fluvaquents soil is moderate to <br />rapid. Available water.capacity is low to high. Effective <br />rooting depth is 60 inches or more for water-tolerant.plants <br />and 10 to 20 inches for plants sensitive to a high water <br />table. Runoff is slow or ponded, and the hazard of water <br />erosion is slight. The hazard-of soils blowing is slight. <br />A high water table is at or near the surface during the <br />spring and early summer. In some areas the water table <br />remains above a depth of 1 foot throughout the year while in <br />other areas the water table is at a depth of 1 to 3 feet <br />during late summer, fall, and winter. The hazard of <br />flooding is frequent. <br />
