Wisconsin streamflow data
Streamflow data are collected by the USGS Wisconsin Water Science Center at over 600 sites on a daily basis. Data from most stations are telemetered by an earth-satellite-based communications system that sends it to the National Water Information System (NWIS). The data are used by many Wisconsin water resource managers to forecast flow extremes, assess water availability and water quality, make water-management decisions, and meet legal requirements. Data available in real-time is used to determine current streamflow conditions in the state and for flood forecasting by the National Weather Service.
All Wisconsin data collected by the USGS are stored and made available to the Nation through the public NWISWeb portal which provide access to water-resources data collected at approximately 1.5 million sites in all 50 States.
Annually, the USGS finalizes and publishes the daily data in a series of Annual Water-data Reports. Wisconsin also publishes a Quarterly Water Conditions report.

Daily streamflow data
The NWISWeb is designed to retrieve data from the distributed National Water Information System (NWIS) databases and push the data to multiple remote webservers for display. NWISWeb strives to provide a Nationally consistent and seamless view of all USGS water data.  USGS streamflow data in NWISWeb
Daily values are summarized from time-series data for each day for the period of record and may represent the daily mean, median, maximum, minimum, and/or other derived value. Daily values include approved, quality-assured data that may be published, and more recent provisional data, whose accuracy has not been verified. Daily time-series summaries from 667 sites
Real-time data are time-series (recorded at fixed intervals) data from automated equipment and represent the most current hydrologic conditions. Measurements are commonly recorded at 5-60 minute intervals and transmitted to the NWIS database every 1-4 hours. Real-time data are available online for 31 days. ALl real-time data are provisional and subject to revision. Real-time streamflow data from 218 sites

USGS WaterWatch displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States. The real-time information generally is updated on an hourly basis.

Peak streamflow data
These data are the annual maximum instantaneous peak streamflow and gage height Peak-flow data from 424 sites

Long-term trend graphs
A duration hydrograph can be used to statistically quantify how much water typically is passing the gaging station and to compare the hydrology of one stream to the hydrology of another stream. The troughs between rainfall-runoff events are an index of base flow, a better measure of drought severity than total flows that include runoff. Duration hydrographs from 5 sites
|
WaterWatch also includes duration hydrographs, a plot of streamflow trends against time or date. Each of the 5 Wisconsin sites has more than 63 years of data.
Duration hydrographs plot selected percentiles of x-day flows versus day-of-year to quantify the variability of flow at a gaging station.
