Description

At the head of the Santa Paula Creek flood control channel an inlet drop structure was constructed in 2000 to maintain sediment capacity and contain flood flows downstream through the City of Santa Paula. The inlet contains a fishway that was severely damaged by floods and debris flows in 2005. Since then repairs have been made to maintain fish passage function and modification concepts have been made to maintain fish passage function and modification concepts have been developed and evaluated. Lessons learned from the original design's performance and the expected performance of the modifications are presented along with the many goals, objectives, and constraints that must be addressed to balance the project demands.

Comments

Jon Mann is a hydraulic engineer and a specific focus on fish passage. During the course of his career, Jon has been an employee of the National Marine Fisheries Service where he provided technical assistance and expertise on many fisheries projects throughout California. Jon helped develop standards and criteria for fish passage assessment and design while serving on many national and state committees related to salmonid habitat and migration. His leadership helped lead to the identification and prioritization of more than 500 fish passage problems at stream crossings throughout Coastal California. At the end of Jon's effort with NOAA's Fisheries Service the systematic restoration of more than 30 of the highest priority sites was completed and fish access had been improved to more than 100 miles of stream habitat. Jon moved to private practice in 2005 and began working for HDR Engineering's Fisheries Design Center in 2009. He is based out of Santa Rosa, CA. His position is to coordinate and lead the practice of fisheries design for HDR in California. The role also includes supervising and preparing alternatives development, hydraulic analyses, feasibility studies, and detailed designs of complex fish passage projects nationwide.
