The Corps of Engineers is replacing the six spillway tainter gates at the Chittenden Locks. These gates maintain the water elevation for Lake Washington. The spillway tainter gates were originally placed in service at the Locks in 1916. In 1944, the gates were refurbished due to corrosion. The last maintenance was done in 1988, when the gates were painted. Because of the age of the materials, corrosion due to the environment in which they operate, and an obsolete design which leaves them weaker and less resilient than modern gates, the Corps is replacing them with new gates. The new spillway gates have an updated design. The gates will operate more efficiently, be easier to maintain, and last a very long time.
