The term SPILLWAY SPOT is related to a DAM, which is a structure built across a river or other body of water to control the flow of water. The three-letter solution for DAM is an acronym for 'Diversion and/or Arrestment of Migratory Waters'. A spillway spot is a location on a DAM where excess water can be released in order to prevent flooding. It is typically located at the bottom of the DAM and is designed to safely divert water away from the DAM and into a downstream area.
