Weeks Falls

Weeks Falls spans 77 feet in height and features three distinct drops along the South Fork of the Snoqualmie River with a width of 40 feet.

The construction of a micro hydro facility upstream led to the diversion of three-quarters of the river's water, altering the natural flow patterns.

Local residents monitor seasonal changes at Weeks Falls, documenting water level variations through photographs and measurements throughout the different months.

Access to Weeks Falls requires driving east on Interstate 90 to exit 38, followed by a right turn and continuation on a gravel path.

The waterfall maintains a consistent 45-degree pitch across its 300-foot run, creating specific patterns in water flow throughout the segmented cascade formation.
