Lake Bistineau December 14, 2009 Update

 

Today, the department is requesting the Department of Transportation and Development close the gates at the control structure at their earliest convenience. There are two recommended reasons for the temporary closure. A significant amount of debris has floated down the lake and it either lodged in or in front of the control gates. Removing the debris can be accomplished safely while the water flow is reduced.

Also, closing the gates allows the lake level to increase, thereby increasing the potential drawdown effect on the plants. Water level fluctuation is one of many tools that can be used to control the salvinia on Lake Bistineau.
