What is a lake drawdown?

For Cravath and Trippe Lakes a drawdown would be performed by opening the dams and allowing the water level slowly lower until the water level is down to a stream bead. A Lake drawdown is one tool that can be used to manage aquatic weed problems. Lake level drawdowns often start in the fall and continue through the winter when water recreation uses are at their lowest. Most aquatic weeds are found near the shallow shoreline. Our drawdown will start on July 8, 2019 and be an extended drawdown that will last until the spring of 2021.
