Watershed Analysis Manual Overview
DNR’s Board Manual Section 11, Standard Methodology for Conducting Watershed Analysis, also known as the watershed analysis manual, is a technical publication required by chapter 222-22 WAC of the forest practices rules.
This watershed analysis manual is used by qualified scientists to assess the condition of public resources such as water quantity, water quality, and slope stability, and to assess the presence of cultural resources including archaeological resources, traditional materials, traditional places, and historic sites. Forest managers then use the public resource assessments to develop site-specific prescriptions that further regulate forest practices within individual Watershed Administrative Units (WAUs), and use the cultural resources assessments to develop management strategies that are implemented voluntarily by landowners and land managers.
