“As an organization dedicated to the protection and restoration of all natural resources in the Royal River watershed, Royal River Conservation Trust stands firmly for the restoration the Royal River to a free-running stream by the removal of both the Bridge Street dam and the East Elm Street dam in Yarmouth, and offers its support to the Town of Yarmouth and others to work thoughtfully but deliberately towards that goal.” RRCT Board of Directors, unanimously, May 2018.
RRCT’s work toward removal of both of the dams owned by the Town of Yarmouth is aligned with the adopted positions of Trout Unlimited (Sebago Chapter), Maine Rivers, and the Earth Stewardship Team of First Parish Church (UCC). This document captures the positions of each of the four organizations.
RRCT’s work toward dam removal is under the umbrella of the citizen-led Royal River Alliance (RRA). The RRA has a website here, and a Facebook page here. The RRA website increasingly is the go-to source for recent documents, frequently asked questions, and more.

- US Army Corps of Engineers, Federal Interest Determination, April 2020. “With Yarmouth’s fish passage barriers addressed in the watershed, up to 135 miles of reproductive and nursery habitat may also be made accessible to migratory fish species, including blueback herring, alewives, American shad, American eel, sea run brook trout, brown trout, and sea lamprey. Restoring fish passage on the Royal River will also benefit mammals and avian predators that prey upon fish species that include bears, foxes, eagles, ospreys and loons. Likewise, water quality conditions may be expected to improve due the resumption of historic flushing patterns.”
- Royal River Alliance letter to Yarmouth Town Council, June 11, 2020. This letter responds to the FERC decision of April 2020. “In summary, the Bridge Street Dam has become an obsolete, unproductive obstacle spanning our Royal River. It has no future other than as an ongoing, growing Town liability and as a continuing unnatural and unnecessary ecological hindrance for the entire Royal River watershed. The recent issuance of the FERC order only serves to highlight the dam’s present and future uselessness. In light of these circumstances, the RRA encourages the Town of Yarmouth to begin consultation with Yarmouth citizens, concerned conservation groups, and any potentially affected businesses and abutters about planning for the permanent removal of the Bridge Street Dam in a manner not harmful to the abutting or downriver property owners.”
- FERC decision regarding Bridge Street dam (Sparhawk), April 2020. FERC removed all future scenarios of hydropower generation at Bridge Street-Sparhawk.

KEY EDUCATIONAL DOCUMENTS:
- Watershed map — river restoration: This map illustrates sea-run fishery restoration potential upriver in Pownal, New Gloucester, Freeport, and other towns, were Yarmouth’s dams removed to restore effective fish passage. According to The Nature Conservancy (TNC), the Royal watershed is relatively unique on the East Coast — a largely undeveloped mid-sized watershed with many miles of main stem and tributaries that can be robustly restored with only the removal of two publicly-owned obsolete dams at the river’s mouth.
- TNC and DEP sediment analysis at Bridge Street (November 20, 2017): The Nature Conservancy (TNC) and the Maine Department of Environmental Protectioin (DEP) conclude that the silt behind Bridge Street impoundment is clean. Here is the November 24, 2017, Portland Press Herald follow-up story. And here is the full source report from Stantec, commissioned by TNC March 16, 2016. No tests have indicated any concerns about the chemistry of the silt behind the East Elm Street dam.
- Stantec (for Town of Yarmouth) sediment quantity analysis at Bridge Street (June 19, 2015): This study (sometimes cited as a 2014 study) address the volume of sediment behind the Bridge Street dam.
- Yarmouth’s Royal River Fishways: Frequently Asked Questions (June 5, 2018): This fact sheet prepared by the Casco Bay Estuary Partnership answers some questions on Yarmouth’s two fish ladders, and summarizes some components of the Interfluve report (below) regarding constraints of the existing fish ladders.

Please send to us additional documents or links that you think should be published or archived here to assist various students, informal working groups, planners, or researchers. RRCT’s adopted goals include river restoration, clean water, and healthy acquatic ecosystems. RRCT has saved many miles of shoreline, but we must do more.

Conservation Law Foundation (CLF) Notice of Intent, Clean Water Act (May 11, 2018). CLF provided notice to Sparhawk Mill interests and Bridge Street Dam owners regarding argued violations of the Clean Water Act. The Forecaster discussed this litigation in a June 6, 2018 article. The Press Herald discussed this litigation in a July 5, 2018 article. The Sparhawk Mill owner responded in November 2018 with a formal petition to surrender (abandon) the FERC exemption (license) along with Appendices thus simplifying scenarios for the future of the dam. In December of 2018, various parties filed comments on the petition to surrender; here are the comments of the Town of Yarmouth and joint comments by Maine Rivers, Trout Unlimited Sebago Chapter, and the Conservation Law Foundation. In December 2018 Maine DIFW and USFWS each filed simple motions to intervene.

Potential to expand hydropower in Maine dries up (Press Herald, February 6, 2015) “After surveying 891 dams, however, the consultants found just 47 sites with the potential to generate additional electricity – a total of 56 megawatts. That is the equivalent of a large wind power facility in Maine and is just one-tenth of the full operating capacity of the gas-fired Calpine power plant in Westbrook.” Yarmouth’s dams didn’t make the list.
