Figure 6. Seasonally averaged diel patterns in near-surface vertical velocity at five ADCP sites, Upper Klamath Lake, south-central Oregon, 2005. The time of maximum and minimum near-surface current speeds and maximum and minimum water temperature top-to-bottom differences are shown for reference. Diel patterns are derived from an average of 30-minute ADCP measurements between June 21 and September 12, 2005. The maximum standard error of the estimate of average vertical velocity is 0.03 cm/s for sites ADCP1, ADCP3, and ADCP7, and 0.05 cm/s for sites ADCP5 and ADCP6.
