This report presents an assessment of the water quality conditions of Pickwick Reservoir based on a survey conducted from April through September 1983, and on other available data. The last water quality assessment conducted by TVA of Pickwick Reservoir was in 1965-66. Pickwick Reservoir is 52.7 miles long and covers 43,100 acres. The average flow at Florence, Alabama, is 51,870 cfs. Unlike most other TVA reservoirs, Pickwick Reservoir does not thermally stratify, although stratification of dissolved oxygen (DO) and, to a lesser extent, pH does occur. Stratification is much more pronounced in the Bear Creek Embayment than in the mainstem. Although low DO conditions (less than 5.0 mg/L) occur in the mainstem, only in the Bear Creek Embayment were near-depletion (1.0 mg/L) conditions measured during the 1983 survey.
