USACE announces Environmental Assessment on Lewisville Lake Dam study

Published Sept. 16, 2016

FORT WORTH, Texas – U.S. Army Corps of Engineers Fort Worth District officials released the Environmental Assessment and Draft Finding of No Significant Impact on the proposed dam safety modifications to the Lewisville Lake Dam today and is seeking comments on assessing the potential environmental consequences resulting from its implementation.
“Life safety is our main priority within the Army Corps of Engineers,” said Col. Calvin C. Hudson II, commander, Fort Worth District. “Our Dam Safety Program seeks to ensure that Corps-managed and operated dams present minimized risks to life, property, and the environment.  Dams are designed and built to reduce flood risk, but they cannot eliminate all risk.” 

The Lewisville Dam is currently functioning as designed, and the probability of failure is remote. While failure is a remote probability, the risk to human life and property should failure occur is high enough to warrant action to address identified deficiencies. Under the proposed action, the USACE would reduce risk of dam failure from seepage deficiencies at two different locations and risk of dam failure associated with spillway instability. All the construction activities associated with the proposed action would be conducted on Lewisville Lake federal project lands.

An open house for the Lewisville Dam Safety Modifications EA will be held on Tuesday, September 27, 2016, from 6:00 to 8:00 P.M., in the Black Box Theater Room at the Lewisville Grand Theater located at 100 North Charles Street, Lewisville, Texas 75057. Copies of the EA will be available at the meeting for review. All written comments must be postmarked on or before October 15, 2016. Comments may be submitted in writing to: Marcia Hackett, USACE, Fort Worth District, P.O. Box
17300, Fort Worth, TX 76102-0300, or via e-mail to Written comments may also be submitted at the public meeting.

The EA is publicly available and the USACE is soliciting comments from the public; federal, state, and local agencies and officials; Native American Tribes, and other interested parties regarding the evaluation of potential impacts associated with the proposed action.
