This site was created as an effort of the Association of State and Interstate Water Pollution Control Administrators to convey important information relating to Total Maximum Daily Loads (TMDLs). Portions of this site have been supported by grants from the United States Environmental Protection Agency. Additionally, the USEPA is also providing technical assistance.

The Goal of this site is to enhance State and local capacity to develop and implement TMDLs and other watershed-based approaches to help solve water quality issues. It accomplishes this task by helping to:

• Educate stakeholders on challenges and opportunities that TMDLs present.

• Share useful information, tools, and effective approaches being used by the States.

• Foster communication among stakeholders and promote involvement in problem-solving at the local level.

• Enhance technical skills.
