Watershed Assessments and Analyses


E&S Environmental conducts watershed assessments and analyses following both state and federal guidelines. E&S has produced numerous watershed assessments for watershed councils following Oregon Watershed Enhancement Board (OWEB) methods, as well as watershed analyses that conform to federal watershed analysis guidelines. In addition, we have completed many assessments of watershed conditions, including water quality, wetlands, and historical watershed conditions.

We completed a prototype watershed analysis of the Trask watershed for the Oregon Department of Forestry and U.S. Bureau of Land Management, following both OWEB and federal protocols. Click here to see some of the watershed assessments completed by E&S Environmental Chemistry.
