Dam removal or modification projects may bring improved fishing and recreation to some eastern Iowa rivers.

Several projects along the Cedar, Wapsipinicon, Maquoketa and Turkey Rivers aim to repeat the success of a white-water course opened on the Cedar River in Charles City in 2011 and a rock arch rapids project opened in the Turkey River in 2010. Rock arch rapids simulate natural rapids using re-engineered or modified low-head dams, many of which have deteriorated over time and were previously not passable for aquatic life, canoes and kayaks.

In addition to becoming new destinations for kayaks and canoes, these projects also remove barriers to fish migration and improve recreational safety. The projects may prevent tragedies like a tubing accident at a low-head dam that claimed one life in the summer of 2014.

The Iowa Legislature recently increased its annual budget for small-scale dam removal and water trails to $2 million, according to a recent report in The Gazette.
