Construction crews drilling piers that will support the apron of the spillway. This is one of many improvements being made as part of the Lewisville Spillway Modification Program. In addition, engineers installed an upstream geomembrane blanket designed to limit seepage beneath the spillway, reducing water pressures that can develop beneath the concrete during flood operations. They also installed more than 70 high-capacity post-tensioned anchors through the spillway weir and into the underlying bedrock. These anchors increase the spillway's resistance to uplift forces and improve overall structural stability. Additional improvements include reinforcing portions of the spillway apron with 936 rock dowels and restoring disturbed areas once construction is complete.
