Augusta lock, dam may be demolished to make way for fish passage to spawning grounds

By David Pendered

The 1937 lock and dam across the Savannah River in Augusta would be demolished in four of the five proposals from the U.S. Army Corps of Engineers in order to build a new fish passage that’s a requirement of the Savannah Harbor Expansion Project.

The Corps doesn’t appear to advocate the demolition of the lock and dam, which it specifically recognized as having historic value for both the region and the nation.

The Augusta City Commission has voted to support the retention of the lock and dam. The structures would anchor plans to build a whitewater rapids destination and the conversion of a 1931 bridge into pedestrian-use only.

The Savannah Riverkeeper calls for keeping the existing lock and the construction of a new rock dam to replace the existing one. The riverkeeper launched a Rock the Dam campaign to drum up community support for this approach.

“We are excited to see the majority of the options being proposed include a rock weir that is compatible with ongoing whitewater efforts, and will bring many benefits to the health of the river, fish populations, and the community,” Savannah Riverkeeper Tonya Bonitatibus said in a statement.

The Corps expects to release a final draft report for public review and comment late this year or early in 2019, according to the script from a June 26 presentation in Augusta.

The fish passage is part of the Savannah harbor deepening project because it is to mitigate the environmental impact of the deepening on shortnose and Atlantic sturgeon. The goal is to reopen access to historic spawning grounds at the Augusta Shoals, which the fish can’t reach because the shoals are north of the lock and dam. This option was chosen after the Corps determined the Savannah area didn’t have enough space to provide adequate mitigation.

The Corps describes the historic nature of the lock and dam in the script used in Augusta:

  • “As a note, the structure is historically significant and eligible for the National Register of Historic Places because of its association with historic trends/events in American history (transportation history) and engineering.
  • “The lock and dam possesses important associations with a long-term cooperative effort by the USACE and the City of Augusta, Georgia to improve commercial navigation along the river. The dam and lock structure retains a high degree of architectural/engineering integrity. Physical changes to the lock and dam have been minimal since its completion in 1937.”

The Corps also provided nuanced language around the notion that it is required to identify the most cost effective project: “[I]t is important to note that the most cost-effective solution is not necessarily the least costly.”

The cost effectiveness of any final recommendation would be compared to the $63 million cost of a project that was jettisoned after Congress approved in December 2016 the Water Infrastructure Improvements for the Nation Act.

The Augusta City Commission has voted to support the retention of the lock and dam. The city is attempting to develop a tourist destination in the area.

Plans include a whitewater rapids park and restoring the 5th Street Bridge over the river and converting it to pedestrian use only. The bridge would improve the connectivity of the network of trails that have been built in the area, Bonitatibus has said.

Engineering costs alone for the bridge exceed $715,000, according to Augusta city records. Construction funding could be provided by the 1 percent transportation sales tax approved in 2012 by voters in the Central Savannah River Area. (This is the transportation tax rejected by metro Atlanta voters.)

    There is no question that the lock will be removed. In none of the designs that the Corp presented during the public open house was the lock shown remaining. The reason is simple: The Corp will not pay to maintain the lock as it is deemed unneeded for river passage. The Corp has also not released any designs that include the whitewater course that is being currently developed. The reason is that the report on the course has yet to be completed and submitted to the Corp and/or the county commissioners.Report
