E&S
Environmental conducts watershed assessments and analyses
following both state and federal guidelines. E&S has
produced eight 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. Recently, we
completed a prototype watershed analysis of the Trask watershed for the
Oregon Department of Forestry and Bureau of Land Management,
following both OWEB and federal protocols.
