Flood Control -- Duwamish River -- Maps

1 map: 39 x 74 cm.<br>Scale: 25 in. = 32 miles.<br>Inset: Profile of river channels from Elliott Bay to Commencement Bay<br>Cutoff channels, levees or dikes, contours, local survey section numbers, and margin of flood plain all indicated on map. <br>In 1906, the Duwamish river flooded so seriously that the entire floor of the Duwamish River Valley was under water and flood waters were backed up all the way to Auburn. Voters approved bonds to dredge the river and provide for flood control, and between 1912 and 1917 the river was drastically altered. Enough land was removed and enough bends straightened that the travel length of the river was reduced from 13 miles to 4 miles. The river was also drastically altered, losing nine feet of depth, in 1916 when the ship canal was opened so that Lake Washington now drained through it instead of through the Black River and into the Duwamish.
