WINSLOW (AP) -A plan to breach a Kennebec River dam to allow sea-run fish to swim farther upstream is being ruled complete, moving the proposal closer to approval.

The town of Winslow’s planning board says FPL Energy’s proposal to partially remove the Fort Halifax Dam is complete. The ruling does not mean the project’s approved.

The town has opposed breaching the dam since it surfaced five years ago. In August, the Maine supreme court denied an appeal by a group of residents who wanted to block the project.

The removal of a dam downstream in Augusta in 1999 allowed the upstream migration of sea-run fish, including sturgeon and striped bass, to Waterville for the first time in more than a century and a half. The Edwards Dam’s removal drew national attention.
