Maine River Drawdown Kills Thousands of Herring

Bangor Daily News: The planned annual lowering of water levels on the Stillwater branch of the Penobscot River caused the death of thousands of river herring—and one Atlantic salmon—last week, but a state official said the impact on the thriving herring resource was minimal.

Brookfield Renewable, the company that manages the Orono Dam, which is just downstream from the bridge on Main Street in that town, said it conducted a planned 3’ drawdown of the Orono impoundment on May 24 in order to make upgrades to the dam. The company installed flashboards to raise the effective height of the dam, as well as barriers to keep boaters out.
