Technical Reports
The Assabet is a well-studied river. Important studies include:
- OARS' Water Quality Reports can be found under the water quality section.
- The Assabet River Nutrient TMDL (total daily maximum load) prepared for State DEP sets out how to reduce the river's eutrophication to meet water quality standards. 2004.
