Spreadsheet Tools for Estimating Watershed Pollutant Loads and Load Reductions

One of the basic steps in developing a watershed plan or a municipal pollution reduction plan (to meet TMDL or MS4 requirements) is to estimate the current pollutant load for the area of interest and the projected load with future development and implementation of best management practices (BMPs). Two key evaluation factors in the section of BMPs to meet pollutant reduction goals are cost and pollutant removal effectiveness. The Center has developed two tools that assist with this work: the Watershed Treatment Model and the Clean Water Optimization Tool.  These two spreadsheets allow customization by users and are free and [...]
