Study tests 2 Ohio rivers for dam removal effects

COLUMBUS, Ohio (AP) — Researchers are studying two Ohio rivers to learn more about the effects on waterways from removing dams.

The Columbus Dispatch (http://bit.ly/QLQPTA ) reports that a team of Ohio State University researchers are testing and monitoring sections of the Olentangy and Scioto Rivers in the Columbus area where two dams came down last year.

Dams back up waterways' natural flow and can adversely affect rivers and their surrounding habitat. But scientists are still trying to determine the effects resulting from their removal.

The chief engineer for the Ohio Water Development Authority that helped fund the study says officials are hoping that the data collected from the project will help them estimate the impact of future dam removal in other parts of the state.

There are more than 4,000 dams in Ohio.
