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 or region.
Month/year period-of-record rainfall summary files by county, District region, or USGS drainage basin for easy graphing, time-series analysis, and model input.
