Keyes Pond High Resolution Temperature Monitoring

Due to sensor failure, data describing surface water temperature conditions from May through October are absent. Data collected during regular water monitoring visits was used to fill in this season’s temperature heat map. The water column of Keyes Pond was weakly stratified when sensors were deployed. Surface water temperatures increased gradually until reaching peak temperature of 29.0 °C (84.2 °F) in mid-July. Surface water cooled slightly in late July and warmed again in early August before beginning a gradual decline that persisted for the remainder of the season. Shallow waters began to cool and mix with waters from the middle depths in mid-August. 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 late October.
