108	Major Flood Stage. Bohemian Highway Bridge at Tyrone Road begins to backwater, with water possibly flowing up and over roadway. Major flooding of creekside and floodplain properties, as well as river crossings. Travel difficult or impossible, and very dangerous.
105	Moderate Flood Stage. Fairly deep and fast-moving water jeopardizing or flooding creekside properties regionally on Dutch Bill Creek, with many lower crossings inundated and impassable. Bohemian Highway Bridge and Tyrone Road are not flooded at gaging site.
102	Minor Flood Stage. Two feet of localized inundation on floodplain. Flooding of low-lying creekside homes and properties is likely already occurring, or is imminent if water level continues to rise. NWS will issue a Flash Flood Warning if not yet already issued.
100	Monitor Stage. Lower inset floodplain inundated, but water level remains well below bridge deck on Bohemian Highway. Some flooding of low-lying creekside properties up or downstream along Dutch Bill Creek could be occurring. NWS will issue a Flash Flood Watch if not yet already issued.
