How long should drawdown typically last for best results?

The recommended duration for a drawdown to achieve optimal results is typically 60-90 days. This timeframe is crucial because it allows sufficient time for the terrestrial environment to establish and for any unwanted aquatic vegetation to be effectively eliminated. During this period, water levels are lowered, which exposes sediment and disrupts the growth of aquatic plants.

This timeframe also provides a window for natural processes, such as the growth of desirable plant species and the reduction of nutrients in the water body, thereby improving water quality and the overall health of the aquatic ecosystem. The 60-90 days period ensures that both the existing and any newly spreading invasive vegetation are adequately addressed, preventing them from reestablishing once the water level returns to normal.
