Four parks around Lake Lanier will now be open only on the weekend due to a budget shortfall, said the Army Corps of Engineers. The Duckett Mill, Bolding Mill, Sawnee and Van Pugh South parks have limited their hours of operation to between 7 a.m. Thursday and 3 p.m. Sunday every week, While the corps’ recreation budget has remained largely consistent over the past few years, the rising cost of operation and maintenance has made it difficult to keep the parks open seven days a week, said Operations Project Manager Tim Rainey. “We went over our recreation budget in previous years and we realized this year that we cannot afford to keep operating the way we have been,” Rainey said.
