Data are tidally affected -- Astronomical
tides cause significant cycles of approximately 24.84 hours at
this site. Because a different portion of the 24.84-hour tidal
cycle is averaged in successive daily (24-hour) computations, a
systematic secondary oscillation, unrelated to basin hydrology
and having a period of about two weeks may be apparent in daily
data.
