Figure 7. Half-hourly current speed and direction recorded at sites ADCP1 and ADCP2 (before August 6) and at sites ADCP3 and ADCP4 (after August 6), Upper Klamath Lake, Oregon, 2004. Shaded time periods denote times of wind and current reversals.
The current direction data from ADCP1, ADCP3, and ADCP4 range from 100 to 460 degrees because 360 degrees have been added to values of current direction less than 100 degrees to avoid the appearance of a large shift when the wind direction varies to either side of north.
