The Pollutant Load Estimation Tool (PLET) uses a user-friendly web interface to calculate:
nutrient and sediment loads from different land uses, and
the load reductions that would result from the implementation of various best management practices (BMPs).
- The Spreadsheet Tool for Estimating Pollutant Loads (STEPL) and the Region 5 Model for Estimating Pollutant Load Reductions are being retired (April 2022). This landing page will remain active during a temporary time of transition.
- Social Indicators Data Management and Analysis (SIDMA) tool: This tool organizes, analyzes, and visualizes social indicators related to nonpoint source (NPS) management efforts through statistical and spatial relationships.
- Social Indicator Planning and Evaluation System (SIPES) (PDF): A step-by-step system for using social indicators to help you plan, implement and evaluate Nonpoint Source (NPS) management projects. SIPES is intended to be used by resource managers who want to learn more about their watersheds.
