Abstract |
A study of the water quality characteristics and biological conditions in Roosevelt Lake was made during the period September 22 to October 1, 1952. Information from this reservoir, a high 'multiple purpose' type of impoundment with water depths up to 385 feet, would be expected to give data valuable in predicting effects of future Columbia River impoundments. Samples of water, plankton, bottom animals and fish were obtained at ten ranges throughout the reservoir to determine existing physical, chemical, bacteriological and biological characteristics. Radiological background information was obtained from some of these samples. |
