Lake Commission updating technology


New gauge will help entity be proactive

  • Halley

Have you ever wondered how officials know the level of Lake D’Arbonne? Who measures the lake to know when it’s getting too high?

Many may say the La. Department of Transportation and Development (DOTD), Louisiana Wildlife and Fisheries or the National Weather Service (NWS). OK, all those play a role, but how do they know?

The obvious answer is by using gauges. Today’s gauges give instant and accurate readings to all these entities, but also to you, sitting at home.

Right now the D’Arbonne Lake Commission is in the process of replacing its downstream gauge. “The gauge we currently have is inoperable,” Commission President Jake Halley said. “It’s been down multiple times. We really don’t have a good power supply or a good way to hang it.”

The current gauge is located on the spillway structure itself, on the downstream side. The plan is to put the new gauge on the bridge on the Rocky Branch cut through road. engineers and Claiborne Electric,” Halley said. “We’re in the final phase of getting prices for the entire project.”

The process will include mounting the gauge on the bridge, which will be done by Delta Processing and having Claiborne Electric run power from an existing pole.

“That gauge will be used by the DOTD to determine when to open the Tainter gates,” Halley said.

The Commission does have a gauge at the State Park that will be upgraded to 4G technology to make it more effective. The current official gauge on the lake is a USGS gauge of the spillway structure itself on the lake side. That gauge is used by the NWS.

“Technology is very important and has allowed us to be proactive on keeping the lake level manageable,” Halley said. “That’s important to all of the areas around the lake, both in personal property and with businesses.”
