Figures 1 and 2 show some particularly bad corrosion occurring in miter gate
compartments that are normally above the water line.
The objectives of this project were to replace worn out miter gate
machinery, all power distribution equipment, all wire and cable, all, instrumentation and controls, install a new SCADA system, upgrade/replace project lighting systems, move all electrical equipment above the 500-year flood level and abate all hazardous materials such as asbestos, lead, mercury and PCB's used in the original construction.

Today's deployment adds to Governor Cuomo's Artificial Reef Initiative, an unprecedented effort launched in 2018 that is deploying large volumes of cleaned, recycled materials from state agencies onto reef sites, including old Tappan Zee Bridge materials; out-of-use Canal vessels; retired Canal lock miter gates
and lift bridge; two retired NYPA turbines and a taintor gate; steel trusses, pipes and rock; and parts of the City Island Bridge.
Unlike the current canal, which uses miter gates
, the expanded canal will have steel rolling gates.
An unorthodox design feature was the use of miter gates
at a double-track crossing that eliminated the need for a center post support.
These gates, called miter gates
, when closed meet an angle like a chevron with the pressure from the water-level keeping the gates closed.
The site includes a lock 140mx12m, which is no longer in service, 160mx17m sluice with two miter gates
, a lock 185mx12m, originally incorporated a 160m airlock with two miter gates
, the length was increased to 185m in the early 70s by the installation of a lifting door to downstream, a dam five assists, a hydropower plant equipped with a fish pass.
The locks provide for vessel passage through the Ocklawaha River, Haines Creek and the Apopka-Beauclair Canal and are controlled by upstream and downstream miter gates
and slide gates.
