Although the last category costs only 5-35% of the other systems, there is no possibility of application to large reservoirs. A typical diffuser system, for use in a TV A (Tennessee Valley Authority) reservoir, had an operating cost of $350,000 annually in 1976 (Krenkel and Novotny 1980). Even assuming that the quality of discharge water is good, some impounded rivers suffer from increased erosion and sedimentation in downstream areas. J / ~ / .......... 4.
