There’s more than one reason lake levels fluctuate


You’ve probably asked yourself this question hundreds of times: Why has the lake level changed? Why is the lake so low? Why are the gates open at the dam? Why does the lake seem so high?

It’s a frequent topic for those living on or visiting the reservoirs in the Brazos River basin. Despite a common misconception, there are few “constant level lakes” in Texas and none in the Brazos River Authority System of water supply reservoirs.

It’s normal for the levels of man-made reservoirs to fluctuate for a few reasons. Though many people assume the worst, there are simple answers to these questions and the Brazos River Authority would like to help.

As part of the BRAs efforts to answer the many questions posed on social media, by phone and email, we’ve created three videos to show you what we do. The short films explain a bit about our organization and operations, why lake levels fluctuate, and how the massive dams operate.

Last week, many of you viewed the first video that addressed the basics of the BRA.

This video is focused on a popular question: Why do lake levels fluctuate?

The BRA hired Washington D.C.-based Flying Colors Broadcasts to produce three educational videos. The company visited each of the BRA-owned and operated reservoirs capturing awe-inspiring footage of Possum Kingdom Lake’s Morris Sheppard Dam, Lake Limestone’s Sterling C. Robertson Dam, and Lake Granbury’s DeCordova Bend Dam. Members of the BRA management team and reservoir managers were interviewed at each location, sharing thoughts and insights into operations.

You can watch the second of three new educational videos now by hitting play on the video above.

You can also watch the first video by clicking here. The third video will premiere Oct. 21.

We hope you enjoy the productions and will share them with friends and neighbors as we all work to protect Texas’ water resources. If you’d like to provide us with feedback, email us at information@brazos.org.
