Duration Hydrograph

Present a time-history of streamflow along with historical streamflow percentiles with capabilites to

  • search all UGSS sites;
  • provide 'alt' color version;
  • overlay historical streamflow, field measurements,and flow criteria; and
  • download flow and statistics.

Area-based Runoff Duration Hydrograph

The area-based runoff duration hydrograph presents a time-history of area-based runoff along with historical runoff percentiles. It is used to display runoff for a state or a water-resource region. Runoff and runoff percentiles can be downloaded. Multiple year types such as water year are supported.

Cumulative Streamflow Hydrograph

Present a graphical presentation of recent cumulative daily streamflow at a site, plotted over the cumulative long-term statistics (median and interquartile range) of streamflow for each day of the year at that station. Observed minimum and maximum annual cumulative discharges are also plotted.

Cumulative Area-based Runoff Hydrograph

Create a graphical presentation of cumulative daily area-based runoff, plotted over the cumulative long-term statistics (median and interquartile range) of runoff for each day of the year. Observed minimum and maximum annual cumulative runoff are also plotted.

Raster hygrograph

Provide pixel-based plots for visualizing and identifying variations and changes in a streamflow data set. The raster hydrographs depict years on the y-axis and days along the x-axis. Users can choose to plot streamflow (actual values or log values) for Daily, 7-Day, 14-Day, and 28-Day streamflow.

Summary of 7-day low flow conditions

Analyze 7-day low flow of an area for a specific period and provide historical comparison with

  • table listing lowest 7-day flows, their ranks, and historical annual minimum 7-day flows; and
  • map showing streamgages with at-or-near new record lows, zero flows, and rank information.

Streamflow conditions map

Customize the streamflow conditions maps (e.g., thumbnail, different size, and different background colors, etc.) and provide a url to be imbedded in web sites.

Streamflow Map Animation

Create a streamflow map animation for a time period for real-time streamflow and flood-and-high flow maps, respectively.

Rating Curve

The rating curve builder is used to create a USGS streamflow rating curve. The rating table is from the USGS ratings depot. Field measurements can also be appended to the curve.
