Lake Byllesby early drawdown planned

The Dakota County Environmental Resources Department plans to lower the Lake Byllesby reservoir to make repairs to the Byllesby Dam beginning Tuesday, Sept. 15.
All boats and docks should be removed by Friday, Sept. 18. The County boat ramps will close for the season at noon Sept. 18, 2015.
The reservoir level will be lowered approximately 8 feet, 6 inches to accommodate the work. The level will remain that low until Nov. 21, 2015, when Dakota County plans to begin bringing the reservoir level to its normal winter elevation of 853.7 feet above sea level. It will remain at that level until May 15 when refilling to the summer elevation of 856.7 feet is permitted to start.
The Minnesota Department of Natural Resources sets seasonal lake levels to make it easier for farmers to get into their lower-lying fields in the spring, and to offer residents the opportunity to enjoy water-related recreational opportunities in the summer.
