Lessons Learned from TMDL Implementation Case Studies
Abstract:Total Maximum Daily Loads (TMDLs) and TMDL implementation plans are being developed across the country using a variety of approaches with varying levels of success. Case studies of watersheds undergoing successful implementation were developed to identify specific characteristics and approaches that facilitated implementation and water quality improvement. Factors that positively and negatively affected implementation efforts were identified based on these case studies. The results of the assessment showed that each watershed presented unique resources and problems, and thus no one approach will guarantee success in all watersheds. However, there are several factors that seem to aid effective implementation; the most common of these were available funding, government agency interest and involvement; stakeholder engagement; and the presence of a TMDL where the pollutant and needed reductions were systematically assessed and quantified. The most common factors negatively affecting implementation efforts in the assessed watersheds included lack of data and lack of funding.
