The Columbia Association announced Monday that the dredging of Lake Elkhorn has been completed, according to Dennis Mattey, CA director of construction.
Dredging of the 37-acre lake began in July 2012, according to a news release, and was the last of Columbia's three man-made lakes to be dredged.
Dredging is done "to maintain the environmental and aesthetic value of the lakes," Mattey said in the release. According to the release, sediment builds up at the lake's bottom, creating conditions that accelerate the growth of aquatic vegetation.
The vegetation can have a detrimental effect, according to the release.
“Restoring the depth to the lake helps to maintain the environmental value of the lake as an aquatic habitat,” Mattey said. “And it looks better, too.”
In mid-March, CA will begin restoring the existing parking lot and pathways. The project is expected to be completed 75 days after work begins.
Work at the 27-acre Lake Kittamaqundi began in October 2010 and ended in January 2012. Work at the 22-acre Wilde Lake began in April 2012 and wrapped up in July 2012, according to the release.
