Keoka High-Resolution Temperature Monitoring

The water column of Keoka Lake was weakly stratified when sensors were deployed. Surface water temperatures increased gradually until reaching peak temperature of 30.0 °C (86.0 °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.
