Watershed Summary Web Service
The Watershed Summary Web Service provides summary information for the types of data (Organizations with data, number of stations, result counts by characteristic type, etc) available within a given watershed (8-digit HUC).

*The Watershed Summary Tool is an example of an application that uses the Watershed Summary Web Service.

Station Web Service
The Station Web Service provides information for all monitoring locations within a given geographic area (geographic bounding box).

*Please Note: The Station Web Service has been revised (as of February 8, 2008) into multiple web methods that provide enhanced data return. These new methods allow users to quickly pull station locations for mapping, return station counts for a given geographic area, or obtain detailed station information if desired.

STORET Result Web Service
The STORET Result Web Service provides direct access to STORET results.

*Please Note: The Result Web Service has been revised (as of March 3, 2010) to provide additional data elements in the outbound schema, as requested by users. Additional data elements include: Result Measure Qualifier Code and Activity Start Time. The service also returns all data element tags within the Result Measure block even if results are not present. Per previous versions of the services, results can be requested via latitude/longitude parameters, or by the type of characteristic a user is searching for. Please note that to ensure good scalability and availability, the result output returned by the Web Service is configured to be restricted by a maximum number of results (20,000). If the number of results requested exceeds the maximum limit, then the web method will notify the end user to narrow down the search criteria in order to reduce the number of results requested. Please refer to the STORET Web Services Consumption User Guide (PDF 641 KB) for a full description of the STORET Result Web Service.

ArcGIS mapping services for STORET
The STORET mapping service provides three end points. One mapping service provides access to the raw data in the warehouse (non-indexed - aka no reach/measure) and the other two mapping services provide access to the indexed data stored in WATERS/RAD which is based on a snapshot of data in the warehouse at a particular point in time.

Description:
Geospatial data for EPA’s Office of Water Programs, including 303(d) Impaired Waters, 305(b) Assessed Waters and Total Maximum Daily Loads (TMDLs) are available for download by state or watershed, as well as at a national extent. Generally, state-level geospatial data represents the most recent data submitted to EPA by states. EPA provides WATERS geospatial data in a variety of formats including Geographical Information Systems (GIS) compatible shapefiles and geodatabases, as well as both vector and raster keyhole markup language (KML) and KMZ files for viewing WATERS data in Google Earth.
