U.S. Rep. Doug Collins, R-Gainesville, is trying to get the U.S. Army Corps of Engineers to respond to a legal issue involving Bolding Mill Park in northwest Hall County. Corps officials said in the fall the agency was trying to determine how a provision in the Water Resources Reform and Development Act, signed into law by President Barack Obama in June, applies to talks between the corps and Hall County over a possible park lease. “Despite my inquiry more than 120 days ago, I understand that corps personnel at Lake Lanier have yet to hear anything in the way of interpretation,” Collins said in a Feb. 18 letter to Col. Jon J. Chytka, Mobile (Ala.) District commander.
