Saint Helens, Oregon - IGNORE HEIGHTS
45.8667° N, 122.8000° W
Note:  The Columbia River is subject to annual freshets.  Short range
predictions are available at local river forecast centers.  The data
for stations above Harrington Point apply only during low river
stages.  There is a tidal influence along most of the length of the
Columbia River.  However, that influence becomes smaller at greater
distances from the Pacific Ocean.  We are able to provide predictions
of the times and height of tides from the Columbia River Entrance to
Harrington Point, Washington.  Above Harrington Point, although there
is still a tidal influence and we can predict the times of the high
and low tides, the water levels experienced are more a result of
freshwater flow in the river than the astronomical tides.  It is for
this reason that the heights of both high and low tides along the
Columbia River, above Harrington Point, are set to a value of 0.0
feet.
Heights for this station should be disregarded--use times only.
