This edition of the WATER CROSSING
DESIGN GUIDELINES (previous editions titled DESIGN OF ROAD CULVERTS FOR FISH PASSAGE) has been completely revised and covers the design of culverts and now
including new chapters on bridge design, tidally influenced crossings,
temporary crossings, culvert abandonment, and project development. These
guidelines were written to help the crossing owner and designer comply with
Washington State law that protects fishlife. We hope that this document
provides practical, real-world knowledge and techniques to improve the overall
success of water crossings.
