Show 22 CLASSIFICATION OF AVAILABLE WATER SUPPLIES (a) Definite underground streams. (b) Underflow of surface streams. (c) Percolating water. (d) Artesian water. These terms may be defined as follows: Watercourse is a definite stream of water in a definite natural channel, originating from a definite source or sources of supply. It includes the underflow. The stream may flow intermittently or at irregular intervals, if that is a characteristic result of the sources of water supply in the area. Lake or pond is a compact body of water with defined boundaries, substantially at rest. The difference between a lake and a pond is in size. A pond is a small lake. Diffused surface water is water that occurs, in its natural state, in places on the surface of the ground other than in a watercourse or lake or pond. Salvaged and developed waters are made available for use by the labor of man. Salvaged water is that portion of water in a water supply which under natural conditions is lost, but which by means of artificial devices is recovered and made available for beneficial use. Developed water is water which in its natural state does not augment a water supply, but which by means of artificial works is added to a water supply or is otherwise made available for beneficial use. Waste, seepage, drainage, and return waters are closely associated and their classifications overlap. Waste water, which may be flowing on the surface or seeping under it, includes water purposely turned back into streams from which diverted, because of operation conditions and requirements affecting the diversion systems; water leaking from ditches and structures; and water flowing from irrigated lands as a result of excessive applications to the soil. Seepage or seepage water is water seeping through the soil, from natural or artificial sources, and entering stream channels or appearing elsewhere on the surface. Drainage water is water flowing in an artificial drain, originating from either natural or artificial sources. Return water consists of portions of water diverted for irrigation or other uses that return to the stream from which diverted, or to some other stream, or that would do so if not intercepted by some obstacle, and may thus include waste water, seepage, and drainage water. Spring water is water that breaks out upon the surface of the earth through natural openings in the ground. Ground water is water under the surface of the ground, whatever may be the geologic structure in which it is standing or moving. Definite underground stream is a watercourse buried in the ground. |
