Crews recently completed the top section of the lake’s spillway, including the 13-foot-tall labyrinth weir that helps control how water leaves the lake and maintains its maximum water level.
With that key piece in place, the intake structure gates were closed, and Lake Ralph Hall officially began to fill in early July. This milestone marks the end of major construction on the reservoir itself. How long it takes for the lake to fill depends on rainfall and could be three to five years. We will continue to share updates as the lake fills. |
