Barrier Culverts 101
Barrier occur at fish passage flows when:
• Water surface drops too much (> 0.8 ft.).
• Water flow is too fast (> 0.4 fps)
• Water flow is too shallow (<0.8 ft.).

nwith "significant habitat" (>200 meters
upstream).
• WSDOT to correct culverts with <200
meters upstream habitat at end of useful
life or through other transportation
projects.
• Notify Tribes of State's activities with time

2006 BARRIER INVENTORY
• Identify Barriers:
• Excessive water surface drop (> 0.8 ft.).
• Water flow that is too fast or too shallow (0i,4 fps/0.8 ft.).
• Measure how much fish habitat is available sIFi eam
of barriers.

• Calculate Priority Index (PI): Bang -for -buck prioritization.
• % Improvement in fish passage.
• Species specific production improvement.
• Habitat gain.
• Condition of fish stock utilizing the stream.
• Rough estimate of project cost.
