Stream Crossing Initiative
Making Stream Crossings Fish Passable
Few people consider the effects of road crossings, utility crossings, and other infrastructure on the quality of stream habitat. Stream conditions may be quite different upstream and downstream of a stream road crossing, and may look different during low or high water. The design and condition of a stream crossing determine whether a stream behaves naturally and whether animals can migrate along the stream corridor.
Fortunately, we have learned how to design stream crossings that allow wildlife unrestricted access to a watershed, maintain natural stream conditions, and help protect roads and property from some of the damaging effects of floods. As such, the U.S. Army Corps of Engineers and the U.S. Fish and Wildlife Service can assist you in designing safe and low-environmental impact stream crossings. Use information within this website to help guide your efforts in designing stream crossings throughout Georgia.
