// Strategic Significance
Toledo Bend Reservoir on the Sabine River is the largest reservoir in Texas and Louisiana and the fifth largest in the US by surface area. It straddles the Texas-Louisiana border and supplies water to communities in both states. The dam was tested severely during Harvey in 2017 requiring emergency water releases that caused downstream flooding in communities along the Sabine River.
// Civilian Impact Assessment
Harvey in 2017 forced emergency releases from Toledo Bend that flooded communities downstream along the Sabine River into Louisiana. Communities along the Sabine River from the dam to the Gulf of Mexico face flooding risk during major controlled releases or dam emergency events. The reservoir supplies drinking water and supports significant recreation economy.
// Evacuation & Shelter Guidance
Sabine River communities downstream of Toledo Bend should monitor reservoir levels especially during major rainfall events. Harvey demonstrated that controlled releases can rapidly flood downstream communities with little warning. Monitor Texas TDEM and Louisiana GOHSEP broadcasts for release notifications. Know your elevation relative to the Sabine River floodplain.
