Willowmoor Floodplain Restoration Project – Dynamic Weir Analysis This is a follow-up to a memo Reid Brockway sent to the Executive Committee dated March 8, 2019, concerning a key problem – extreme flooding of Lake Sammamish in peak inflow events – that the Willowmoor-sponsored Preliminary Dynamic Weir Analysis Technical Memorandum (DWA) did not adequately address.
This 20-minute video presentation provides background facts and factors surrounding Lake Sammamish’s mismanaged water levels and repeated flooding of shoreline properties.
This is to highlight what I believe to be the most pressing issue concerning the Sammamish River flood control and the Willowmoor project. It is a problem with a solution, achievable with active flow control via a dynamic weir.
