A long-awaited project to stabilize the earthen dam at Lake Knickerbocker could begin in three to four months, an official with the Gainesville Department of Water Resources said. Holding up the project is a review of proposed upgrades at the site by the U.S. Army Corps of Engineers, which has jurisdiction over the property, according to Myron Bennett, manager of the engineering and construction division for city water resources. Bennett said the city cannot move forward on the project until the Corps of Engineers grants permission because the dam is on Corps property.
