I can't find the article, but I "thought" they were not supposed to be more than partially full due to a problem with the earthen structure being inadequate to support them full

In 2012, the Corps said the pair of dams had an "extremely high risk of catastrophic failure." The designation made Addicks & Barker two of the worst dams in the nation.


and this:  https://www.houstoniamag.com/articles/2015/5/6/will-the-addicks-and-barker-dams-fail-may-2015

...the task of protecting the city from flooding has grown ever more difficult as the areas upstream of the dams have become more developed and more water runs off into waterways rather than being absorbed into the soil. And then there's all the development downstream, which creates its own runoff, limiting how much water can be released from the dams into Buffalo Bayou. The upshot? During extreme rain events, both reservoirs will fill more quickly and be expected to hold more water for longer periods of time.

"It's all applying additional pressures to the dams," says Richard K. Long, who supervises the Addicks and Barker dams' day-to-day operations for the Corps.
