A. The water column of Trickey Pond was weakly stratified when sensors were deployed in mid-May. Shallower waters gradually warmed through May and June. Deep waters stayed cold but warmed slightly during this period.
B. Surface water temperatures increased rapidly in July with peak temperature occurring on July 29 (26.6°C/79.9 °F) and continued to be very warm through mid-August. Deep waters stayed consistently cold.
C. Surface waters began cooling later in August before briefly warming again in early September. Deep waters were cold but began to warm slightly.
D. Shallow waters began to cool and mix with waters from the middle depths. Deep waters were still cold but continued to warm. 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.
