HISTORY: Soon after construction of the GIWW, rapid shoaling became evident at this crossing and these structures were built to provide safe navigation across the river crossing and minimize shoaling at the crossing and in the GIWW. The project was completed in Sept. 1943 by Tellepsen Construction for $3,343,000.
GENERAL DESCRIPTION: Two Flood Gates consisting of two Sector gates each located on each side of the Brazos River along the GIWW. Gates and chambers are 75’ wide with sill elevations of -16’ MLLW, sealing depth of 22’ and operate on rack and pinion drives. Each gate weighs 150,000 lbs or 75 tons. The project is operated by a Lockmaster, Operator Supervisor, Mechanic, and 10 Lock and Dam Operators. IMTS job and structure model is currently in place.
