Historically, the Sammamish River meandered through a wide swath of valley bottom wetlands, which provided natural flood storage. From the early 1900s through the mid-1960s, the river was straightened by a series of drainage district projects. In 1964, the U.S. Army Corps of Engineers formalized these efforts through the Sammamish River Flood Control Project – a nearly 14-mile long project from Lake Sammamish to Lake Washington to provide flood protection for the Sammamish River valley.
