Total Maximum Daily Load Reports

WMP and TMDL Reports Search Tool

Total Maximum Daily Load (TMDL) reports are assessments of water quality in rivers, lakes, and streams in a given watershed where impairments exist. The report contains an overview of the waterbodies, the sources of pollutants, the methods used to analyze data, reductions in levels of pollutants needed to restore water quality, actions that need to be taken to reduce pollutant levels, and actions that are being taken to improve water quality. A watershed management plan (WMP) is a strategy and a work plan for achieving water resource goals that provides assessment and management information for a geographically defined watershed.

Use the WMP and TMDL Reports Search (WATRS) Tool to find TMDLs and watershed planning efforts in your area. A full list of completed and ongoing TMDL projects are listed below.

A TMDL Report will fall in one of three categories:

  • TMDLs Under Development: These TMDLs are being researched and written and the progress is noted in the table.
  • TMDLs on Public Notice: These TMDLs are in the final stage of approval and are in a Public Comment Period. A public comment period typically lasts thirty (30) days. All comments should be sent to the project manager on or before the close of business on the date listed.
  • Approved TMDLs: These TMDLs have been approved by the U.S. Environmental Protection Agency, and are available to view, print, or download.
