Abstract The effects of destratification on a water supply impoundment were studied over a three year period. Prior to destratification, baseline information on physical, chemical and biological parameters was established. Destratification was accomplished by the use of the 'Air-aqua' system which creates vertical circulation in a body of water by the release of small bubbles from hoses laid on the lake bottom. In addition to a monitoring program to establish changes in physical and chemical characteristics of the water, the plankton populations, benthic organisms and periphyton accumulations were studied. Also, a creel census was taken and information on the operation of the water treatment plant which uses University Lake as a raw water supply was analyzed.
Highlights Notes Studies the effects on physical, chemical, and biological parameters of thermal mixing by aeration.
