By June 1, 1937, all timber foundation piles have been driven in the east cofferdam and construction of concrete formwork is beginning. The top of each pile has been cut to a specified level to accommodate the overlying concrete floor of the lock structure. Looking south, the lock structures in each cofferdam, called gate blocks, are nearly identical. (MWRD photo 23166)
