Siletz River Terrain

Submitted by Anonymous (not verified) on

The Siletz River is located in west-central Oregon. The Siletz Tribe has requested technical assistance through BOR’s Tribal Assistance Program to evaluate hydraulic and geomorphic processes along the Siletz River. Historical aerial photos of the river will be evalutated to document geomorphological changes and the spread of invasive species over several decades.  Bathymetric survey data will be combined with lidar data to build a complete topographic surface from which cross-section geometry data will be extracted and used to support hydrologic modeling of the river. The technical information from the evaluation will help guide the development of management alternatives to improve salmonid habitat in the study area.
