Book excerpt: Excerpt from Water-Quality Study of a Reach of the Merced River in Yosemite National Park and Vicinity, California: April 1973 Through September 1974 The Merced River, in and near Yosemite National Park (fig. 1) is a prime scenic attraction. Each summer, vacationers are attracted to the river and its environs in Yosemite Valley. In addition to having esthetic appeal, the Merced River is used for fishing and swimming; water from the river is used for power generation, and for the park water supply. Since 1931, a sewage treatment plant near Yosemite Village (no. 6 in fig. 1) has discharged effluent into the river. During l975 76, the National Park Service plans to construct a new sewage-treatment plant (secondary treatment with phosphorus removal) near the Merced River about 2 mi km) downstream from the western park boundary. Effluent from the new treatment plant will be discharged into the Merced River downstream from El Portal (fig. Although contamination of the Merced River from the new treatment plant is not anticipated, the California Regional Water Quality Control Board Central Valley Region, has required the National Park Service to insure that water-quality standards in the river are not violated. To evaluate subsequent changes, water-quality data are needed prior to operation of the treatment plant. To provide this water - quality base data, the National Park Service requested in 1973 that the u.s. Geological Survey start a water-quality study at sites upstream and downstream from the proposed sewage outfall. Fieldwork began in April 1973 and ended in September 1974.

This book was released on 1981 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water-quality conditions in the Merced River in California were sampled four times during the 1977 water year at 12 stations on the river and its major impoundments. Samples taken at the record or near-record low flows of the 1976-77 drought, showed that calcium and bicarbonate were the predominant ions in the water. Inflow of irrigation return water to the river caused a threefold to sevenfold increase in specific conductance between river kilometer 42 and the farthest downstream station at kilometer 8. During the four sampling periods, the increase in total nitrogen concentrations was twofold to sixfold in that reach. Upstream of kilometer 42, the river was free of apparent water-quality degradation, with the exception of occasional increases in nitrogen and phosphorus. Measurements of primary productivity and phytoplankton in Lake McClure and at three river stations gave indications of trophic conditions in the river system.

Book excerpt: Excerpt from Water Quality in the Merced River Above and Below the El Portal Sewage Treatment Plant Near Yosemite National Park, California, 1975-77 The purpose of this study was to examine and describe any differences in water chemistry and periphyton growth in the Merced River upstream and down stream from the treated sewage discharge at Rancheria Flat near El Portal. The approach of this study included measuring selected physical, chem ical, and biological characteristics and constituents at four sites on the Merced River and one site on the South Fork Merced River (fig. 1, table Physical characteristics included streamflow, specific conductance, and water temperature. Chemical constituents and properties consisted cu? Nitrogen, phosphorus, silica, dissolved oxygen, alkalinity, and ph, with emphasis placed on measuring plant nutrients. Biological constituents consisted of periphyton with emphasis placed on measuring their abundance. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
