Ausable Flooding: Smarter Culvert Designs Benefit Fish And People

Tropical Storm Irene Runoff CulvertMost people don’t think about culverts, the large pipes that carry streams and runoff underneath our roads. Even with their essential role in our transportation infrastructure, culverts tend to be in the spotlight only when they fail. In dramatic ways, Hurricane Irene and other recent storms have put culverts (and bridges) to the test. Unfortunately, the high water from these storms overwhelmed many culverts, washing out roads, causing millions of dollars in damages across the Adirondacks, and disrupting life in many communities. For example, the town of Jay sustained about $400,000 in damage to its culverts and adjacent roads as a result of Irene. Across the Northeast, the story is much the same.

Following Tropical Storm Irene, I was part of a team of conservation professionals to assess the performance of road-stream crossings (i.e., culverts and bridges) in Vermont’s Green Mountain National Forest. The peer-reviewed study, published in the current issue of Fisheries, found that damage was largely avoided at crossings with a stream simulation design, an ecologically-based approach that creates a dynamic channel through the structure that is similar in dimensions and characteristics to the adjacent, natural channel. On the other hand, damages were extensive, costly, and inconvenient at sites with stream crossings following more traditional designs. » Continue Reading.
