Ice Control Structure

Before the Ballville Dam was removed, it played a critical role in breaking up upstream ice before it reached downtown Fremont. To prevent future ice jams, an Ice Control Structure was constructed just downstream prior to the dam’s removal.

Today, this structure doubles as a highly effective debris catcher—particularly for trees floating downriver. Credit where it’s due: local authorities have done an excellent job of cleaning debris off during low water conditions, ensuring it remains functional and safe.
