Step 1Understand the problem.
Explore SWAMM's pollutant mapping across the watershed.
Nitrogen, phosphorous and sediment pollution is generated at different rates, depending on landuse,
soil type, rainfall patterns and topography across the watershed.
This pollutant generation was mapped as part of the Lake Springfield Watershed Management Plan 2016, and is now
available through SWAMM.
It's important because excessive sedimentation is reducing the lake's storage capacity, making the Springfield’s water and power supply
more vulnerable to drought and climate variability.
