  "definition": "1. A stream or reach of a stream that flows briefly only in direct response to precipitation in the immediate locality and whose channel is at all times above the water table.\n\n2. A stream drainage that is usually dry and fills with water only during brief episodes of rainfall. Many desert streams ephemeral.\n\n3. A stream which flows part of the time, usually after rainstorm, during wet weather, or for only part of the year. Also referred to as an ephemeral stream. Stream on or in contact with the ground water table that flows only at certain times of the year when the ground water table is high.\n\n4. An ephemeral stream has flowing water only during, and for a short duration after, precipitation events in a typical year. Ephemeral stream beds are located above the water table year-round. Groundwater is not a source of water for the stream. Runoff from rainfall is the primary source of water for stream flow.",
