Sabine County, Texas-

Even if they weren't all cousins, they were kindred spirits. The "What Went Under" Toledo Bend sparked huge interest over the past several months as planning came together to share the personal history of one of the largest man made structures in the south. As the newly built dam began to fill the power generating reservoir with water at a rate more quickly than anticipated, families rushed to save homes and property by moving to higher ground. 

Attached is some great footage of this year's event.

In April, 1964, construction of dam, spillway, power plant and Pendleton Bridge was initiated, and by October, 1966, water impoundment had begun. 

Toledo Bend Reservoir had filled with water by late spring of 1969, and the power plant had begun operations.

On Oct. 22, 2011 more than 270 past and present residents of Sabine County, and Sabine Parish began arriving at the first "What Went Under?" reunion. Local historian Weldon McDaniel displayed 500 never before seen photos. The event was an old fashion dinner on the ground, and lots of story telling of days gone by. "There's more photos to come courtesy of the Sabine River Authority," McDaniel said. When the SRA purchased the property photos were taken of every home, fence, outhouse, barn, pen, located on the land.  "What inspired us to hold this reunion was a little book written by A.A. McGraw, titled What Went Under?  McGraw was a lifelong resident of Sabine County, and wrote his memories down to share with his children, and their descendants. 

And that is exactly what his son, Terry McGraw has done. He recently created a social media group, that has quickly grown as family members reminisce about a simpler time.
