Figure 15. Observed and simulated current speed and direction at two Acoustic Doppler Current Profiler (ADCP) sites in Upper Klamath Lake, Oregon, 2006. The error bar placed on graphs of speed indicates the root mean square error (RMSE) between the observed and simulated currents over the length of the simulation. The current direction ranges from 100 to 460 degrees because 360 degrees have been added to values of current direction less than 100 degrees to avoid rapid numerical changes when the current direction moves from east to west of north, and vice versa. The current direction is referenced clockwise from north and is the direction to which the current is moving.
