  "term": "Water Level Gauge",
  "field": "Environment",
  "definition": "A device that facilitates the measurement of the level, or stage, of the upper surface of water in a reservoir, channel, natural water body, stilling well, or groundwater well. A water level gauge may be as simple as a graduated staff mounted in the water that is to be measured, a float, or it may be a more complicated device that measures (1) water pressure at a point below the surface or the level of the water surface, or (2) travel time of a sound wave and its echos generated and received at a point above the water surface. A water level measurement device that both measures and records the position of the water surface is often termed a water level recorder or water stage recorder.",
