The vegetation which occurs along the valley bottom is not of the <br /> type associated with a riparian habitat. The channel is sharply incised <br /> into the soil mantle, refer to Hydrology Section for depth to gro und water; <br />with the chaiuiel incised approximately 10-20 feet into the material. <br />Further downstream, the deepness of the incision is greatly increased. <br />The vegetation found in the meadows paralleling the stream channel is a <br />canbination of perPnn;al grasses (wheatgrass), sagebrush and annual <br />for~bs~. The wal11l,,of the valley channe inspected to determine depth <br />of root penetra't~on. The inspection revealed that the roots were generally ` <br />contained in the upper six feet of soil material and did not extend in ~~ <br />v <br />the water table. ~~ <br />The information presented in the Hydrology and Soils Section along ' <br />with the map of the site indicate that flood irrigation of the area is <br />not feasible. This is based on the fact that 600 acre-feet is the <br />expected flow down the Canyon and sufficient undisturbed area does not <br />exist for the prudent farmer to start an operation. <br />Based on the above, TBM requests the Division make a negative AVF <br />DetPrm.nation based on: 1) lack of water to support flood irrigation <br />of the land, 2) historic information indicating~no flood irrigation <br />in the area, 3) there is no subirrigation of the lands in question, <br />and 4) the area has been dramatically disturbed in the past and no <br />suitable undisturbed areas exist on which to develop a farming operation <br />based on flood irrigation. <br /> <br />VI-2 <br />
