Fish Passage Improvement

Bateman Creek culverts that were removed

Culverts that were installed under roads many years ago often pose problems for fish passage.  The culverts may not have been sized properly for current flows which causes overland flooding.  This increases sediment delivery to the stream.  This sediment can carry pollutants and plug the interstitial spaces in gravel beds.  Over the years the culverts may have collapsed, which totally blocks fish passage.  In other cases the streams have undercut the culverts and there is a large drop between the culvert and the stream bed.  This is a large problem for fish passage.
