About this station
NOAA builds the predictions for Clam Bay, Rich Passage from the SEATTLE (Madison St.), Elliott Bay station: high tides about the same height, 3 min later; low tides about the same height, 4 min later.
Puget Sound and the Columbia estuary amplify mixed tides far inland — ranges past 10 ft in the South Sound — with river flow stacked on top.
