National Management Measures
- From Agriculture, July 2003
- From Urban Areas, November 2005

- Spreadsheet Tool for Estimating Pollutant Loads (STEPL): STEPL employs simple algorithms 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).
- Region 5 Model for Estimating Pollutant Load Reductions: The Region 5 Model is an Excel workbook that provides a gross estimate of sediment and nutrient load reductions from the implementation of agricultural and urban BMPs. It does not estimate pollutant load reductions for dissolved constituents.
- Social Indicators Data Management and Analysis (SIDMA) tool: EXIT 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): EXIT 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.
