Project: Anadromous Fish Floor (AFF)

The purpose of this project is to identify measurable physical stream characteristics downstream from which anadromous fish habitat would be presumed and to compare those measurable characteristics against field observation data throughout the state. The study is designed to assess which combinations of gradient, channel width, vertical and non-vertical barriers to migration, and other physical habitat and geomorphic conditions are most often associated with anadromous fish use. This will 1) identify habitats where anadromous fish use is presumed using specific physical metrics and 2) provide one potential starting point upstream from which water typing surveys are conducted using FHAM.

Please note: The timeline for the implementation and data analysis phases of this project have not determined yet and are not included in the timeline below. This will be updated as timelines for those phases are established.
