The Duwamish River crested Tuesday (Jan. 18th), and as it rose it brought a tethered boat down with it, as seen in these photos shot by Photographer David Sharpe (click images to see larger versions):
This was near 12100 East Marginal Way, just north of Metro Transit’s south base (see map below).
When the river started rising it caught the corner of the boat and little by little it got pulled under.
This boat was moored via tether off of private land.
The Duwamish is fed by the Green River, which this week reached a Phase 3 Flood Stage, according to the USGS.
