# SWAMM: Spatial Watershed Assessment and Management Model

> Open geospatial platform for collaborative watershed pollution management. Maps
> nonpoint-source nitrogen, phosphorus, and sediment loading at field resolution,
> tracks Best Management Practice (BMP) installations, and measures progress toward
> Clean Water Act TMDL goals for Lake Decatur, Illinois.

SWAMM is used by the City of Decatur, IL, watershed landowners, conservation districts,
and environmental consultants to plan and track agricultural BMP implementation across
the 925 square mile Lake Decatur Watershed. The platform calculates pollutant load
reductions per BMP and generates grant application reports. Built on GeoNode 5.x,
Django 5, and GeoServer.

Target users: municipal stormwater engineers, conservation district staff, agricultural
landowners, environmental consultants, and grant program administrators working on
nonpoint-source water quality improvement.
