Great Works Dam Removal Project

The Great Works Dam was located on the Penobscot River in Old Town and Bradley, Maine, and the property is owned by the Penobscot River Restoration Trust. Removal work on the dam began in early June 2012 and was largely complete by the end of November. Contractor R.F. Jordan and Sons of Ellsworth, Maine removed approximately 10,000 cubic yards of material from the river, including concrete, timber, and rockfill.

History

The original Great Works Dam was constructed in the 1830s and partially demolished in approximately 1887 when the current Great Works Dam was constructed. The current dam was originally constructed and owned by the Penobscot Chemical Fibre Company. Diamond International Corporation acquired the mill and dam in 1968. The dam and powerhouse facilities were sold several times over the next few decades, and were most recently purchased in 2010 by the Penobscot River Restoration Trust from hydropower company PPL Corporation, based on an agreement that was signed in 2004. The agreement allowed the Trust to purchase certain dams in exchange for energy generation enhancements at other sites in the Penobscot watershed, with the aim of rebalancing the use of the river to accomodate the 11 species of native sea run fish that attempt to use the river to migrate each year while maintaining hydropower generation capacity.
