On March 15, 2016, Texas Commission on Environmental Quality (TCEQ) Dam Safety was notified by the Tyler Regional Office that significant damage occurred to the dam structure during storms the week of Marcn 11, 2016, Images in local news reports show evidence that the service spillway pipc has falled and the downstream bank is severely eroded. The downstream portion of the service spillway plpe apparently broke off within the embankment and the uncontrolled flow of water eroded a large portion of the downstream embankment. Available images indicate that a vertical scarp extends Into the downstream side of the crest almost to the centerline of the dam. ‘Thasa observations indicate that the dam integrity could be compromised and potentially cause a breach of the dam and lass of the reservoir. Of immediate concern is the polential for inundation of the downstream floodplain. Mr. Gary Bartuska page 2 March 16, 2016 The potential for failure of the dam prompts the TCEQ to require you to initiate the removal or repair of the dam within 15 days from the date of this letter. ‘At a minimum, this will involve the following: 1) lowering the lake level as soon a5 possible, 2) retaining a licensed professional engineer, and 3) submitting a written response to this leller with a plan and timeline for either repairing the dam or removing it. In addition, you should compile the names and phone numbers of ali affected downstream property owners and contact local emergency management officials to formulate a plan of action In the event of a dam fallure.

We applaud your effort to restore the dam to a safe condition. Ilowever, TCEQ dam safety rules require that you retain the services of a licensed Texas professional engineer (P.F.) ta prepare plans and oversee the permanent repairs to the dam. Fallure to do so would be a violatian of 30 Texas Administrative Code (TAC) §299.4. TCEQ Dam Safety Rules (30 TAC§299.45) do allaw for a provision tor emergency repairs. But, even these are required to be supervised by a P.E, And, upon resolution of the emergency, require plans prapared by a professional engineer for permanent stabilization of the structure, It Is strongly encouraged that you retain the services of a P.E. to guide continuing lake lowering efforts such as operating siphons, notching the dam to prevent engagement of the damaged pipe splliway, stabilizing erosion af the embankment material, as well as designing and overseeing permanent repairs to the embankment and spillway.
