State Forests Watershed Analysis Project
Watershed Analysis Projects
The Oregon Department of Forestry (ODF) conducts watershed analysis projects in basins containing State Forest land. These projects evaluate the interactions between ODF management and a watershed’s physical and biological processes.
 
ODF watershed analyses are designed to be performed in several steps.
  • The analyst compiles available information to describe current watershed condition.
  • Based on this description, factors limiting important watershed functions are identified and assessed.
  •  The analysts and ODF resource specialists determine whether riparian and aquatic strategies are addressing the appropriate process and function concerns within the watershed.
  • Information provided by watershed analysis will be used to refine district implementation plans and, as necessary, contribute to a comprehensive review of forest management plan goals and strategies.
As watershed analysis projects are completed, the project reports, with selected supporting materials, will be posted at this site.
