Poe Ship Arrestors

Davis and Poe Pumpwells ($37.3M FY21 Capability)• The pumpwell system will serve all locks (including new lock); system >100 yrs old• Delayed funding for repair increases O&M every year with additional interim risk

reduction measures required and increasing probability of failure; greatly increases operational risk to navigation. Locks must be dewatered in 10 hours due to extreme cold temps in January.

• Original 1914 manifold is most critical component; has lost half its wall thickness • New Pump Well will be contracted with the New Lock to reduce risk associated with 2

contractors working in close proximity at the same time.
