Drawdown refers to the planned lowering of water levels in reservoirs or dams that power hydroelectric facilities. It's like managing the water in a bathtub - operators need to carefully control how much water they release and keep to generate electricity. This process is important for both power generation and maintaining safe water levels during different seasons or maintenance periods. Understanding drawdown is crucial because it affects how much power a facility can produce and when they can produce it. The term might also appear as "reservoir drawdown" or "dam drawdown" in job descriptions.
