WaterWatch -- Toolkit

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.

Present a time-history of area-based runoff along with historical runoff percentiles.

• Display a state or a water-resource region.
• Easy to download flow and statistics
• Support multiple year types

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.

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.

View WaterWatch dynamic maps in a place.

• View all kind of streamflow conditions maps
• Provide tools for quick zooming, panning, and full-screen.
• Search USGS streamgages easily by state, huc, and site name and number.

Display a seamless dynamic real-time streamflow condition map. With zooming, more details are shown.

Display a seamless flood and high flow map. Map shows 4 categores of NWS flood stages: action, minor, moderate, and major.

Display hourly flow change map. Highlight sites with increasing and decreasing flows.

Find USGS streamgages by region, river name, or site number. Display sites in a dynamic map. Show summary of streamflow and link to various USGS and AHPS sites in popup.

Compare the current stage and NWS flood stage with recorded peak stages of previous floods. The tool allows users to

• select a stage or flow chart,
• specify peak values and dates,
• control what peaks to show,
• overlay flood stage, and
• change legend description.

Compare streamflow conditions of two dates by displaying two maps side-by-side.

• Compare real-time, flooding, daily, 7-day, 14-day, and 28-day maps
• Select state or Water-Resource region
• Download historical maps archived on WaterWatch

Provides a list of basic summary statistics and a duration graph for a streamgage, as computed from daily values, for the period of record. Download streamflow statistics for all current streamgages.

Disaply streamflow measurements for a period and in an area. Highlight the number of measurements and the number of measurenements during flooding.

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.

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.

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.

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

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.

Monthly, quarterly, and annual HUC runoff time-series plots are avialable in a HUC area and a state.

Hydrologic unit runoff and runoff condition maps from 1901 to 2015 are available.
