Rainfall

48 rain gauges across the county, ordered by season total. The season runs from October, which is how the water year is counted here.

24 rain gauges listed on page 2, plotted at their published coordinates; marker size follows water-year rainfall.
The 24 rain gauges in this page of the index. Larger diamonds indicate a higher season total since October. 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.
