Stream Gauges

119 stream sensors across Santa Clara County. 32 of them publish numbered flood thresholds.

23 stream gauges listed on page 5, plotted at their published positions over Valley Water's major-watershed layer.
The 23 stream gauges in this page of the index, plotted at the coordinates in Valley Water's sensor feed. 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.
