Gauge Location

2 stream gauges whose Valley Water threshold descriptions name I-680. — The point marks the gauge locations whose published threshold text names I-680; 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.

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.
