5. What is “Watershed Assessment”? “Assessment is used to mean the analysis of watershed information to draw conclusions concerning the conditions in the watershed.” (Nehalem River Watershed Assessment, 1999, Portland State University) "The biology lives in the hydrology, and the hydrology flows over the geology." (Mattole River Estuary - Dynamics of Recovery, 1995, by the Mattole Restoration Council) A watershed assessment is: a science-based process for analyzing a watershed's current condition and the likely causes of these conditions.”
