Fish Passage Design for Road Crossings Workshop and Field Tour
19 - 20 April 2022
9:00am - 5:00pm
Workshop Coordinators: Michael Love P.E., Michael Love & Associates, Inc., Ross Taylor, Ross Taylor and Associates, and Kristen Kittleson, County of Santa Cruz
This two-day workshop will focus on fish passage design approaches and techniques for road-stream crossings and other low-head barriers. The course will be structured around Part XII – Fish Passage Design and Implementation - of the CDFW California Salmonid Stream Habitat Restoration Manual. The workshop is intended for participants with a variety of backgrounds, including engineers, biologists, geologists, planners, and project managers.
Covered topics include:
-
Biological imperative of providing passage
-
Assessing geomorphic risk for a fish passage project
-
Pre-design and selection of project approach
-
Stream simulation design and reference reach characterization
-
Roughened channel design
-
Use of boulder and log weirs
-
Retrofits and technical fishways
Workshop participants will work on sample problems taken from real projects, including analysis of thalweg profiles, developing designs for a stream simulation culvert crossing, and sizing material for a roughened channel. Participants should bring a calculator and a ruler. The second half of Day 2 will include a field tour to a range of fish passage sites within Santa Cruz’s Corralitos Creek. Sites include full replacements and retrofits of stream crossings and a fish ladder, illustrating the various design approaches covered in the workshop and described in CDFW Part XII.
