STORET Warehouse Watershed Summary

The STORET Watershed Summary shows the types of data available in the STORET Warehouse for a selected watershed (such as metals, nutrients, or pesticides data), who has entered the data, the period of record for the data, and how much data are available.

The Watershed Summary shows summary data for 8 digit HUCs, or Hydrologic Unit Codes. An 8-digit HUC is a watershed at a certain scale. If you do not know the 8-digit HUC that you are looking for, or to find the HUC nearest to you, please refer to EPA's Surf your Watershed website.
