Aquatic Organism Passage at Road-Stream Crossings

Many of Vermont's existing stream crossings are barriers to movement of fish and wildlife.

good stream crossing versus obstructed passageImproving stream crossing design and construction practices insure passage for Vermont’s fish and wildlife populations and improve flood resiliency.

For reasons as simple as the need to escape extreme floods or as complex as maintaining genetic diversity, animals living in or along streams need to be able to move unimpeded through the watershed.

Here are several resources on stream crossings and aquatic organism passage that highlight the benefits of well-designed stream crossings and stream continuity.
