Intermittent stream
Intermittent stream means a stream or part of a stream that has flowing water during certain times of the year when groundwater provides water for streamflow. The water table is located above the streambed for only part of the year, which means that intermittent streams may not have flowing water during dry periods. Runoff from rainfall events and snowmelt is a supplemental source of water for streamflow. Intermittent streams include only those conveyances with channels that display both a bed-and-bank configuration and an ordinary high water mark.
