Abstract:

This report documents the results of comprehensive water quality studies performed in Hartwell Lake HW during the period January through December 1992. Presented in this report are summaries and comparisons of water quality conditions observed during monthly in situ sampling trips and biannual chemical sampling trips within the main stem and two major embayments on Hartwell Lake. The onset of thermal stratification began in Hartwell Lake during early March and by mid-April, extensive stratification was present from the headwaters of each major embayment to the forebay. Anoxic conditions were observed in the middle reaches of the Seneca and Tugaloo Rivers during the July sampling trip. The greatest concentrations of chemical constituents within the two embayments were also recorded during the mid-July sampling period. By mid- October, stratification in the upstream regions had diminished due to normal seasonal cooling, but persisted in the deeper waters of the forebay until early November. Intensive physicochemical sampling during July, revealed increased concentrations of specific nutrients and organic carbons normally associated with anoxic conditions in the bottom waters of an embayment.
