Fish passage engineer Michael Love will begin the series with an overview of Part XII of the CDFW Salmonid Stream Habitat Restoration Manual, summarizing contemporary design approaches and implementation techniques for providing fish passage at existing and replacement stream crossings and other in-stream structures.  It will cover the stream simulation approach, culvert retrofits, and grade control techniques that include boulder and log weirs, geomorphically-based roughened channels, and pool-and-chute fishways.
