The U.S. Army Corps of Engineers (USACE) will temporarily shut off water flows from Canyon Dam into the Guadalupe River at Sattler on Wednesday to allow an inspection team to enter and inspect the conduit.
The dam, control tower, conduit, stilling basin, spillway and other associated facilities will be examined to ensure water-control infrastructure is properly maintained and functions as designed to manage flood risk and dam safety missions.
“We understand the downstream impacts of no flows and work to ensure that these are minimized as much as possible,” Canyon Lake Manager Javier Pérez Ortiz said in a statement today.
Periodic inspections are performed every five years.
Canyon Lake’s flood-control replacement work with the Tennessee Valley Authority (TVA) continues to progress despite a change to the original schedule.
TVA is expected to return to Canyon Lake the first week of March to resume onsite work that also will impact downstream water releases.
In November 2023, the Corps announced plans to replace Canyon Dam’s floodgate. April 15 is the anticipated completion date for that project.
USACE also said construction at Overlook Park will be completed by the end of February instead of January, as previously announced.
Schedule updates will be shared with the public as they become available, Javier Pérez Ortiz said.
