Rainfall summaries by climate division (tables & maps)

Tables of rainfall summaries for each climate division are available. Separate summaries are provided for the differing durations of rainfall: from spring to the current date, the warm growing season, the beginning of the calender year to the current date, the water year through the current date, and the last 30, 60, 90, 120, 180, and 365 days.
Recent rainfall learn more

Recent rainfall

The Recent Rainfall table shows the total rainfall (in inches) for each Mesonet site. Rainfall totals are given for the past 7, 10, 14, 30, 60, and 90 days up to the current date, as well as the total for the current month, year, and previous year.
Flood & high flow conditions from the USGS learn more

Flood & high flow conditions from the USGS

The Flood and High Flow map produced by USGS shows the location of streamgages where the water level is currently at or above flood stage, or at high flow. The high flow conditions are expressed as percentiles that compare the current immediate flow value to historical daily average flow values for all days of the year.

Streamflow conditions from the USGS

Map of real-time streamflow compared to historical streamflow for the day of the year.
Departure from normal streamflow from the USGS learn more

Departure from normal streamflow from the USGS

Departure from Normal Streamflow from the USGS provides detailed drought information. A map of your chosen state shows areas that have experienced below normal streamflow (in percentile classifications) based on a historical seven day average for that particular day.
