    culvert
  • (culverts) clay or cement piping placed in wetland areas to channel water. Culverts alter the naturally existing movement of water through the area.

  • a transverse and totally enclosed drain under a road or railway

  • Channel (a stream or drain) through a culvert

  • A culvert is a device used to channel water. It may be used to allow water to pass underneath a road, railway, or embankment for example. Culverts can be made of many different materials; steel, polyvinyl chloride (PVC) and concrete are the most common.

The completed culvert replacement at Davis Creek includes logs placed along the channel sides to slow bank erosion and produce complex fish habitat. The rootwad visible on the right will create a local scour pool to provide cover for fish and substrate for aquatic insects.

Evaluation of a Predictive Model for Upstream Fish Passage Through Culverts






Fish diversity in the United States has been declining because of pollution, invasive species, and continual habitat degradation and fragmentation. Recent studies have shown that culverts at road crossings can fragment habitat by acting as barriers to the upstream movement of fishes. This prevents essential spawning migrations and inhibits recolonization of streams after natural or anthropogenic disturbances. With over 50,000 road crossings on eastern National Forest lands, these crossings can represent a serious threat to the viability of native fish fauna. Currently, there are few predictive models or software available that address fish passage through culverts, and those models have not been validated with field experiments. I developed 3 models for fishes common to the Mid-Atlantic Highlands region of the United States that predict whether a culvert is impassable or passable to upstream fish movement based on physical culvert characteristics. I validated these models using a mark-recapture movement study at 26 road-stream crossings on national forest lands in Virginia and West Virginia during the summer and fall of 2004. Culverts, regardless of model classification, appeared to impede upstream movement by stream fish. Fish movement through culverts classified as impassable was lower than movement through the natural stream for Salmonids during the summer and fall and for some Cyprinids during the fall. Movement by species from the families of Salmonidae, Cyprinidae, Percidae, and Cottidae through passable culverts (76 events) occurred 5 times as often as movement through impassable culverts (16 events). Fish movement through culverts was negatively correlated with the culvert characteristics of slope, slope x length, and velocity for cyprinids. Road crossings with outlet drops < 10 cm, slope < 2.0%, and slope x length values < 25 experienced the greatest movement illustrating the importance of those culvert characteristics in determining fish passage. The models were modified based on the results of the field experiment to increase their accuracy. The final predictive models from this study can be an effective tool for assessing fish passage through culverts and aid natural resource managers in prioritizing and implementing fish passage projects.
