Spillway is a specialized skill that involves controlling the flow of water in a waterway or river. A spillway can be constructed as a part of a dam or other water control structure to manage the flow of water through the structure. A spillway operator must be able to monitor water levels and flow rates, and adjust spillway gates to maintain safe conditions for downstream communities and infrastructure. This requires knowledge of hydraulic engineering and environmental regulations, as well as the ability to make quick decisions in emergency situations.
