// Strategic Significance
Keystone Dam on the Arkansas River approximately 15 miles upstream from Tulsa is the primary flood control structure protecting the entire Tulsa metropolitan area. The dam impounds Keystone Lake and releases controlled water flows to prevent catastrophic flooding of the city. During Hurricane-remnant rainfall events and major flood seasons, Keystone Dam releases are the primary mechanism managing floodwater through the Tulsa metro. Uncontrolled releases or dam failure would produce catastrophic flooding across Tulsa, Sand Springs, Jenks, and Bixby.
// Civilian Impact Assessment
The Tulsa metro's flood risk is directly managed by Keystone Dam release operations. When the Corps of Engineers must release high volumes of water, downstream communities along the Arkansas River face flooding. Residents in the floodplain below Keystone should monitor Corps of Engineers water release announcements as a primary preparedness action during major rainfall events.
// Evacuation & Shelter Guidance
Monitor US Army Corps of Engineers Tulsa District water release announcements. Arkansas River floodplain communities including Sand Springs, west Tulsa, Jenks, and Bixby should have pre-planned evacuation routes to higher ground. Follow Tulsa County Emergency Management directions.
