Figure 2. Diel patterns in the difference between water temperatures measured near-surface and near-bottom at sites MDN (4.5 m depth), EPT (12.5 m depth), and MDT (14.8 m depth) in Upper Klamath Lake, south-central Oregon. Diel patterns are derived from an average of hourly monitor measurements between June 2, 2005, and October 9, 2005. Minimum temperature differences occur between 07:00 h (sites MDN and EPT) and 08:00 h (site MDT); maximum temperature differences occur between 16:00 h (site MDN) and 19:00 h (site MDT). The maximum standard error of the estimate of the average temperature difference is 0.07 ºC at sites EPT and MDN, and 0.14 °C at site MDT.
