Science in Your Watershed

Links By Watershed:

Find Science In Your Watershed and Additional Water Resource Links in Your Watershed by using:

  • Locate Watersheds - this mapping interface tool allows users to subdivide a water resource region map of the United States from Regions to Subregions, Accounting Units and finally to Cataloging Units - through the use of the hydrologic units codes (HUCS). This application gains access to watershed information for all of the 21 U.S. regions, which includes Alaska (19), Hawaii (20) and Puerto Rico (21).

    There are "Additional Information for this Watershed" links available directly under every Cataloging Unit map for every HUC. This dynamic link searches, creates and finds specific information associated with your watershed.

  • Mapping Interface with Selection Menu - This Mapping Interface and Pull-Down Selection Menu combination work together to help you find your watershed. The menu interface will automactically map to your watershed selection. If you select a non-existing HUC value, a "Message From the Web Page" will help you determine the correct HUC value selection and map to the best selected watershed map. This application gains access to watershed information for all of the 21 U.S. regions, which includes Alaska (19), Hawaii (20) and Puerto Rico (21).

  • Pull-Down Selection Menu - This Pull-Down Selection Menu generates the same result as the Mapping Tool above - except it does not use a mapping interface. This tool gains access to watershed information for all of the 21 U.S. regions, which includes Alaska (19), Hawaii (20) and Puerto Rico (21).

  • Single Cascading Menu - This Menu basically operates as the one above, but is more memory intensive. You may have to click CONTINUE to allow the script to continue to load. All HUC names and values are viewable through this menu interface. This tool gains access to watershed information for all of the 21 U.S. regions, which includes Alaska (19), Hawaii (20) and Puerto Rico (21).

  • ***Hydrological Regional API Interface (these links are located directly under every 01-21 Region map)- This new interface utilizes the ESRI javascript API accessing NWIS daily streamflow conditions at sites with real-time or recent surface-water, groundwater,or water-quality data. The colored dots on this map depict streamflow conditions generated from WaterWatch as a percentile, which is computed from the period of record for the current day of the year. Only stations with at least 30 years of record are used. The small green triangles indicate stations that were not ranked in percentiles either because they have fewer than 30 years of record or because they report parameters other than streamflow. Some stations, for example, measure stage only. HUC boundaries are also linked to the "Additional Information for this Watershed" page for every watershed. Improved mapping functionality includes zooming, pan, dynamic scale, dynamic lat and long reference, Locate Your Address field, clickable Switch Basemap (9) layers, and a closeable location map.
