The maximum is in midwinter, decreasing gradually from spring to autumn and increasing slightly in midsummer. In most years, precipitation is adequate for crops and pastures. Droughts are short and infrequent. Streams, springs, and ponds provide water for livestock. Deep wells provide an adequate supply of water for most domestic and municipal uses.
Most streams flow intermittently and are often dry in summer and in autumn except after rainstorms.
A few large reservoirs are in the area. The dominant soils are Udults and Ochrepts. They have an udic moisture regime, a thermic temperature regime, and mixed mineralogy. They are over sandstone and shale and are mostly moderately fine textured to fine textured. Areas of rock outcrop are common on these sites.
