Rainfall Data Summaries

Rainfall summaries are available as spreadsheets for downloading to your computer. Summaries are tabulated by specific geographic areas, such as county or drainage basin boundaries. Each page within a spreadsheet shows period-of-record rainfall totals (based on area-weighted average values) for 1915 through the previous calendar year by month, wet season, dry season, calendar year, or water year.  You may select a datafile by county, USGS drainage basin, basin board, region, or CWM watershed delineation.  The spreadsheets are in Microsoft Excel format to make it easy for you to create graphs and further analyze the data, if desired.

How to download the spreadsheets...
