The hydro release was 11,600 cubic feet person and the gates were at 33,400 cubic feet per second. the Total release was at 45,000 cubic feet per second.
These elements and others are monitored by the Tulsa District Hydrology team.
“With the pool continuing to drop the plan is to begin decreasing releases starting tomorrow (Tuesday), see planned gate change schedule below,” the release said.
Tuesday, the two gate changes will allow for a decrease to 30,000 cfs total and Thursday, the two gate changes will decrease to 20,000 cfs total.
There will be one gate change on Tuesday, July 1. The conduit gates will be closed and only hydropower will remain open to have a decrease of 12,500 cfs.
“The timing of the final gate change may be moved depending on the pool elevation,” the release said.

“As always, please use the forecasts as guidelines and know that the forecasts only consider rain that has been received on the ground and does not consider projected or forecasted rainfall,” the release said. “As a result, the forecasts are subject to change.”
These updates are provided to stakeholders to give information about the plans related to Lake Texoma and the Red River.
“As you are all aware there are numerous competing stakeholder interests involving Lake Texoma although flood control, water supply, hydroelectric power, regulation of Red River water flows, improvement of navigation, and recreation are the official project purposes there are many other stakeholder interests that are taken into consideration,” the release said. “USACE team members strive to make the best resource decisions based on what is best for the mission, the Nation, and the public, understanding impacts to all stakeholders.”
