A. The water column of Sand Pond was weakly stratified when sensors were deployed in mid-May. Shallower waters gradually warmed throughout May before a slight, short cool down in early June. Deep waters stayed cold but warmed slightly in late May.
B. Surface water temperature increased steadily from mid-June throughout July with peak temperature occurring on July 29 (27.1°C/ 80.7 °F). Deep waters stayed cold but began to warm slightly.
C. Surface waters began cooling slightly throughout August before reaching near peak temperatures in early September. Deep waters stayed cold and stable.
D. Shallow waters began to cool and mix with waters from the middle depths. The decrease in temperature difference between shallow and deep waters is a precursor to fall turnover.
E. Temperatures throughout the water column were becoming more uniform but temperature differences in the deep waters indicate that full mixing had not yet occurred when sensors were retrieved in early November
