Watershed Assessment & Planning

Finding What's Wrong And Fixing It

The goal of watershed assessment and planning is to improve our waterways by reducing sediment and nitrogen by incorporating global strategies for improving water quality. These improvements help our clients to meet the Environmental Protection Agency’s Total Maximum Daily Load which is usually referred to as TMDLs, and National Pollutant Discharge Elimination System Requirements.

Each Watershed is Unique

We begin by assessing existing conditions today; both physical and biological, then use that information as a base to create an assessment along with information from previous studies and GIS. From all of that information, we begin identifying potential improvements and creating a plan that also incorporates community involvement and buy-in.

For these TMDL impairments and others, our AMT team can provide a pollutant load analysis that will identify the location, quantity and magnitude of the dominant pollutant contributors in the watershed under existing and future conditions. Depending on the level of remediation needed, the plan can include anything from stream stabilization with planting to retrofits and community education and engagement.

Our team has extensive experience in a variety of pollutant loads characterization methods including the Simple Method, pollutant rating curves, and deterministic water quality models such as SWMM, HSPF, QUAL2E, and WASP.
