Watershed-based plans determine the level of pollutant load reduction or habitat restoration required, specific locations where best management practices are needed, and how to measure water quality improvement.
Watershed-based plans work toward quantifiable water quality goals to either restore impaired waters, or to meet long-term goals for high quality waters. For funding for Clean Water Act Section 319 funds, watershed-based plans must include required EPA elements. See Section 319 Guidance for Watershed-based Plans for more information on the EPA Section 319 funding criteria for watershed-based plans.
