How many dams does the state of Washington have?1166 dams:CONCERNING THE CASCADIA SUBDUCTION ZONES

Morning Steve,
Thank’s for the info on Cascadia. Yes, they are not prepared. Seattle is built on “fill”. As people model out what will happen when the buildings, infrastructure collapses, and Tsunami and every one anticipating what will be coming from the west.
No one is looking behind them for what will surely come.

'Today there are 281 hydropower (electricity) dams larger than one-tenth megawatt in size in the Columbia River Basin and about 200 more dams built for other purposes, such as irrigation and flood control.'

'How many dams does the state of Washington have?
1166 dams
According to the Washington State Department of Ecology, there are 1166 dams in the state. King County has 124 dams, almost twice as much as any other. The largest dam in Washington, in terms of structural volume, reservoir capacity and electricity production, is the Grand Coulee Dam on the Columbia River. '

If the sidewalls and bedrock shift as it surely will, it won’t take much for these 80-100 year dams to let go. A major collapse up stream will domino collapse all downstream dams.
Never seen anyone address that aspect of Cascadia.From J.S.
