Approved TMDL Projects

This list represents the total number of Washington State TMDL projects approved by EPA. For those projects approved from 1998 to current, the number of TMDLs are derived based on Ecology's 1998 Memorandum of Agreement (MOA) with EPA based on the TMDL settlement agreement.

Waterbodies are arranged by Waterbody ID Number (WBID). The WBID is made up of the WRIA and segment number:

WA-{WRIA #}-{segment #}

Select by WRIA:
