WS3 - Hydraulic Jacking Workshop & Tour

The workshop will be held at the Bureau of Reclamation’s Technical Service Center in Denver, Colorado and will include a visit to the hydraulic jacking research facility and a tour of Reclamation’s world-famous hydraulics laboratory where current studies include valve testing, pump intake studies, spillway and fish passage models, cavitation research and more.

The registration fee includes the workshop, materials, transportation to and from the convention center, and lunch. All participants are required to ride the bus to and from the workshop. No PPE is required for this trip, but closed-toed shoes are required for the lab tour. US Citizens are required to provide a "REAL ID" to enter the facility. Participants without a "REAL ID" will require an escort. Non-US citizens will be required to provide a full name, birthdate, and passport information to be reviewed in advance. Waivers will be required for all participants.
