Army Corps of Engineers to hold public meeting April 4

The U.S. Army Corps of Engineers (USACE) Louisville District will hold a public meeting from 11 a.m. to 3 p.m., April 4, at 843 Sassafras Rd. in Sassafras.

The USACE has been operating Carr Creek Lake at a target summer pool of elevation 1028.0 feet since 2009. This elevation is 1.0 foot higher than the project’s original summer pool elevation of 1027.0 feet.

The USACE is required to follow written guidance known as Engineering Regulations (ERs) whenever changes are made to the operation of USACE-owned reservoirs, such as Carr Creek Lake. The latest ER, dated May 30, 2016, includes a section on Public Participation in Water Control Plan Development and Revision.

The purpose of the meeting on April 4 is to remain compliant with the ER and allow members of the public to review the Engineering Documentation and the Reservoir’s Guide Curve, which lists the summer pool as being 1028.0 feet. Note that this is the same summer pool that has been observed since 2009. No change to the project’s post 2009 operation is being proposed.

In the late 1980’s, the Louisville District, USACE, completed a Reconnaissance Report for providing adequate water supply to the communities and rural areas in the Upper Kentucky River Basin in southeastern Kentucky. Subsequently, the Carr Creek Water Commission approached the Louisville District and inquired about using Carr Creek Reservoir as a source of water supply. The original request was to withdraw 6 million gallons per day from Carr Creek Lake.

The USACE performed an engineering analysis and developed a Water Supply Reallocation Report which indicated the summer pool would need to be raised from 1027.0 feet to 1028.5 feet to accommodate a withdrawal of 6 million gallons per day. Prior to finalizing the agreement, the Carr Creek Water Commission lowered its request from 6 million gallons per day to 2 million gallons per day. Subsequent engineering analyses indicated the summer pool should be raised 0.75 feet to 1027.75 feet to accommodate the 2 million gallons per day withdrawal.

Before the pool raise to elevation 1027.75 feet was initialized, it was decided that a summer pool elevation of 1028.0 feet would be targeted. This would accommodate the request of 2 million gallons per day and would allow for minimal future increases. The Louisville District has been targeting elevation 1028 for the summer pool level since 2009.

The public will have the opportunity to ask questions about the Engineering Report during the open house. Corps representatives will address questions on the report and the recommended adoption of the current summer pool elevation.

Inquiries may also be emailed to LRL-Pagemaster- UKL@usace.army.mil or mailed to the Army Corps of Engineers, 843 Sassafras Rd., Sassafras, KY 41759. The Louisville District will accept inquiries until April 3.

The Corps will answer all pertinent questions by posting the question and response to the website. For those mailing their inquiries, a copy of the Corps reply will be posted to the website and mailed to the sender.
