No permanent man-made structures are located within 200' of the affected area. <br />d. The Piedra River, flowing south, is adjacent to the Project Area. The owners of <br />the parcel have water rights from the Piedra River of 5 cubic feet per second. <br />Any water utilized from the river will be metered to ensure compliance. Only the <br />Piedra River will receive drainage from the Project Area. Existing water quality <br />in the area has not been assessed for this stretch of the Piedra River (EPA: <br />http://iaspub.epa.gov/waters/enviro.wcontrol?p id305b+COSJPI06B 8800). The <br />depth of the static water table is approximately 25' to 35' based upon information <br />from water wells in the general area (water well information provided by Division <br />of Water Resources). Per USGS National Water Information System, the annual <br />average water discharge for the Piedra River at the Arboles gauge station ranges <br />from a low of 53.5 cfs in 2002 to a high of 822.2 cfs in 1979.
