WATERS Expert Query Tool

This query allows you select key data elements to build a tabular report or a Comma Separated Value (CSV) file for downloading.

There are 3 steps to follow to generate a query:

  1. First, select one view of interest from the list below.
  2. Select columns (data elements or fields) from the selected view.
  3. Enter your search criteria to target specific records from the database.
The Expert Query Tool User's Guide will provide you with detailed information on how to use the Expert Query Tool.

Step 1: Start by selecting one view to be the focus of your query.

 

Clean Watersheds Needs Survey (CWNS) Information
Approved Federal Needs EPA approved needs of the estimated capital costs for water quality projects and other activities eligible for SRF support as authorized by the 1987 CWA Amendments.

Cross Program Information

These database views show the results of spatial queries that determine if a spatial overlap exists between entities of two different water programs. Like any spatial query, errors in determining the overlap can occur and they can be grouped as follows:

  • False Positives occur when the locational information of one the entities is either incorrect or not of sufficient quality to determine it's exact location.
  • False Negatives occur when locational information is missing or not available for all of the entities.
In addition to the entity locational information, errors, although few, may also exist in the spatial network of rivers, streams, and other waterbodies that comprise the National Hydrography Database (NHD) jointly maintained by USGS and USEPA. Errors in the NHD may contribute both to false positive and false negative readings.
