The Penobscot River Restoration Project removed the Veazie Dam in 2014 and the Great Works dam in 2013. These dams, despite their fishways, had blocked the migration of many species of fish since they were built over 100 years ago. In addition, these dams, like most other large dams, disrupted sediment transport, increased water temperatures and provided habitat for invasive predatory species of fish. Many other hydroelectric dams on the Penobscot River are now reassessing their fish passage facilities since the listing of Atlantic salmon as endangered has spread to the Penobscot River. This process of relicensing is governed by the Federal Energy Regulatory Commission. (FERC). The Pin is able to participate in these evaluations and discussions through its fisheries biologist. Through this process, the ancestral fishing traditions and cultural connections of the PIN, along with the treaty reserved sustenance fishing rights of the PIN can be preserved and restored for future generations of Tribal members.
