Predictive Analysis of Dissolved Oxygen in Dickey Lake, Maine
Abstract
Dickey Lake is a northern Maine impoundment proposed by the U.S. Army Engineer Division, New England. Project purposes are peaking power generation (including pumpback operation), flood control, and general recreation. The purpose of the study was to provide information on the expected dissolved oxygen (DO) regime in Dickey Lake. Two approaches were used to investigate the expected DO regimes. The first approach was a comparison of the temperature and DO regimes found in 25 lakes located in Maine, Vermont, New York, and Quebec, Canada. An attempt was made to select lakes that had similar depths, surface areas, and geographic locations with respect to Dickey Lake. This information was used to project the DO regime expected in the far field in Dickey Lake, out of the direct influence of the pumpback jet, and to arrive at general conclusions concerning some of the coves and embayments. The second approach was an attempt to band the DO expected during the incremental filling period. This was accomplished by selecting appropriate benthic and water oxygen uptake rates from the literature and calculating the potential hypolimnetic DO concentrations at the end of the summer stratification period.
