The Effects of Artificial Destratification on the Water Quality and Microbial Populations of Hyrum Reservoir

Résumé du livre

Hyrum Reservoir, Utah, was studied for one year and then for a year following the initiation of artificial destratification. The redistribution of dissolved oxygen to the lower depths of the reservoir significantly increased the amount of habitat suitable for trout. The annual Aphanizomenon bloom increased during that first year after initiating destratification. The nitrogen cycle and the vertical distribution of bacteria were altered as a result of the elimination of the thermocline. During destratification the total suspended solids were highly affected by annual runoff, spring and fall overturns, and destratification; sediments, the increased Aphanizomenon bloom, higher nutrient concentrations, more uniform microbial and nutrient distributions all resulted from these hydraulic factors working singly and in combination.
