Fish and river habitats affected by dredging

Researches have been exploring the effects of dredging on the Kansas river.

Using acoustic Doppler instrument to map the river bottom, they have found that, on average, the Kansas river is about a 1.5 metres deep but when dredges are active they have detected holes up to 15 metres deep.

“We’re not prejudging whether dredging is a bad thing, but there is at least a temporary habitat alteration going on,” associate professor of geography at Kansas State University, Melinda Daniels said.
