SPAWNING VEGETATION This report is concerned with the man-made SEDIMENT changes in the lower Colorado River brought COLORADO R. about by river channelization. River channel dredging has decreased the value of the Colorado River as a habitat for game fishes by: (1) draining the adjoining backwater lakes and sloughs; (2) eliminating riparian vegetation cover; (3) eliminating the eddies and "holes" along the river littoral zone; (4) increasing water turbidity; (5) increasing bank erosion; and (6) reducing the amount of spawning area. 52. Berwick, V. K. 1962. Floods in Utah, magnitude FLOW and frequency. U. S. Geological Survey HYDROLOGY Circular No. 457. 24 pp. A procedure is presented for estimating the magnitude and frequency of floods within the range of the base data, for the majority of Utah sites. A separate analysis was made for major rivers affected by diversion and regula- tion of those not affected by man. (Wydoski) 53. Bessler, M. B., and J. T. Maletic. 1975. SALINITY Salinity control and Federal Water Quality WATER QUAL. Act. ASCE Journal of Hydraulics Division POLLUTION 101(5):581-594. MANAGEMENT The Federal Water Quality Act, Public Law 92- 500, and its amendments have established a national goal that the discharge of pollutants into navigable waters be eliminated by 1985. It is evident that even an advanced basinwide salinity control program like the Colorado River Water Quality Improvements Program (CRWQIP) under the Bureau of Reclamation is not sufficient to meet the anticipated standards and "zero discharge" goals of PL 92-500. This paper examines the overall planning strategy under the CRWQIP and some of the inherent 31
