Comparative Limnology of Several Reservoirs in Central India

AbstractTwenty four reservoirs in Central India were investigated for their physical, chemical and biological features. These reservoirs differed significantly in their size, physical features, chemical composition and vegetation. Three medium and major reservoirs recorded comparatively low electrical conductivity. All the eighteen minor reservoirs showed high conductivity and low transparency since they were all situated in densely populated urban areas polluted by human faeces and domestic sewage. The most abundant ions in water are calcium, carbonate and chloride. The phytoplankton was found to be dominated by Cyanophyceae. Rotifers dominated among zooplankton. All the minor reservoirs are highly eutrophicated. Among the major reservoirs Tawa Reservoir is oligotrophic while others are mesotrophic to eutrophic in nature.

COMPARISON OF RESERVOIRS WITH DISSIMILAR SELECTIVE WITHDRAWAL CAPABILITIES: EFFECTS ON RESERVOIR LIMNOLOGY AND RELEASE WATER QUALITY

Between 1970 and 1980, studies were conducted on several Corps of Engineers impoundments in Oregon, U.S.A., to determine the effects of radically different outlet structures on reservoir limnology and release water quality.The 13 dams in the Willamette River Basin provide only limited capability for selective water withdrawal. Most of the projects (12) have outlets positioned at only one or two elevations, with two-level outlets spaced close together vertically at some dams. This has contributed to water quality problems in reservoirs and downstream, as exemplified by Hills Creek Project which traps highly turbid flood flows below the two outlets positioned 7 m apart near the center of the vertical axis of the dam. As a consequence, downstream release flows remain turbid for months and years thereafter. Additionally autumn drawdown for flood control storage gradually lowers the photic zone into the depth of withdrawal, sending summer accumulations of phytoplankton, organic detritus and nutrients toward do...

Air Injection for Control of Reservoir Limnology

This article discusses the use of compressed air to force circulation and counteract stratification in Lake Wohlford Reservoir owned by the Escondido Mutual Water Company in San Diego County, California, in April 1961. Eighty hours of air injection at approximately 210 cfrn reduced the top‐to‐bottom temperature differential from 16.5°F to 2°F. Reservoir stratification was thus eliminated, allowing reaeration of the entire body of water.
