WD Mayo Tainter Gates

WD MAYO FACT SHEET

Tulsa District utilizes stoplogs of varying lengths as a closure and dewater structure for Tainter gates across the McClellan-Kerr Arkansas River Navigation System locks and dams. These stoplogs are placed via floating plant crane into specific stoplog “slots” within the concrete piers upstream of each Tainter gate.  

Multiple stoplogs (quantity varies by pool elevation) are stacked into these slots to form a barrier between the reservoir and Tainter gate, which allows inspections and repair work to be performed in the dry.  Tulsa District has an inventory of (17) 60’ stoplogs. Currently, all 60’ stoplogs are deployed to support Tainter gate repair projects at Newt Graham and WD Mayo Locks and Dams. Should emergency inspection or closure needs arise, Tulsa District does not have additional 60’ stoplogs to deploy. Moreover additional stoplogs would allow multiple gates to be taken out of service concurrently, increasing efficiency of current and future repair projects. Tulsa District has a completed design for 60 foot stoplogs; funding is needed to procure additional 60 foot stoplogs and lifting beam to facilitate inspections, gate repairs, and emergency closure capability.

  • Tulsa District currently has a limited inventory of 60’ stoplogs that support critical gate inspections, emergency gate closures, and gate repair projects.
  • Tulsa District has already completed 60’ stoplog design; funding is needed for procurement.
  • 60’ stoplogs can be deployed interchangeably across multiple locks and dams on the McClellan-Kerr Arkansas River Navigation System (MKARNS).
