A Look at Why Lake Sammamish is so High
Posted By Dwight on June 29, 2010
If you’re wondering why the water level on Lake Sammamish is at an all-time high, take a look at this video.
In it you’ll see the area around the weir that sits between Lake Sammamish and the Sammamish River. This small area is the only outlet for Lake Sammamish. It looks like the vegetation below the weir is backing the water up over the top of the weir and restricting the flow at the outlet.
I have asked both King County Flood Control and the Army Corp of Engineers why the lake is so high this year; it will be interesting to see what they have to say.
