Delayed since mid-December, the Reston Association’s project to inspect and repair Lakes Audubon, Anne, Newport, and Thoreau dams will finally get under way later this month.
In a statement posted to social media, Reston Association will start work on January 25 on the trash racks and riser structure in Lake Audubon. This requires lowering the lake on January 21 and 22, a foot and a half to two feet a day. That work is expected to take a week.
Then, on February 1, the organization will draw down the lake again, this time to a total of eight feet, to allow for a full inspection of the dam infrastructure. It will be drawn down no more than a foot a day, so this work could talk up to one and a half weeks.
Due to this, Lakes Anne, Newport, and Thoreau will also be lowered to prevent spillage.
Later that month, February 15, more dam inspections will be done. This is expected to take until February 24. Once finished, the lake will be allowed to refill naturally which could take up to a few months to happen.
Reston Association asks all residents to provide slack in their moor lines so that boats can lower safely with the water level. The lake bottom will be “deep mud” so do not attempt to walk on it, RA advises.
Every year, the Reston Association performs these inspections and repairs. They are a state requirement, Chris Schumaker, Director of Capital Projects, tells Reston Now via email.
The project was initially pushed due to “delays both in the fabrication and delivery of key materials for the Lake Audubon trash rack and valve replacements,” writes Shumaker.
Update on Lowering of Lake Audubon and Dam Inspections:
After a meeting with our contractor, we have an updated timeline for the upcoming inspections and work on the dams on RA lakes, which will include lowering Lake Audubon.
