Gauge Location
The point marks the gauge locations whose published threshold text names Willow Street; it does not claim a coordinate for the street or landmark. All eleven polygons in Valley Water's published major-watershed layer are shown. The eleven published polygons do not exactly match the portal's five sensor groups and do not provide a boundary for every named creek.
Stream gauge
A place named here is not a flood prediction. It is what Valley Water records as at risk when a creek reaches that level. For an emergency, call 911.
