The Automatic Project is located on the Messalonskee Stream in Waterville Maine. The project was originally constructed in 1924 and is located approximately 5 miles downstream of the Rice Rips Development (LIHI # 59). There are two other hydroelectric facilities on the river licensed under the same FERC license (FERC No. 2556) as Rice Rips: Oakland (LIHI #60) is located upstream of Rice Rips and Union Gas (LIHI #58) is located downstream of Automatic. Operation of Automatic is dependent on inflow from Messalonskee Lake and discharge from the upstream Oakland and Rice Rips developments.
The project includes: a concrete gravity dam, Tainter gate, spillway, flashboards, intake section, retaining wall, concrete and brick powerhouse, and a horizontal Francis turbine.
The concrete gravity dam is an 81-foot-long, 33-foot-high structure with a 33-foot-long non-overflow section. There is a 20-foot-long by 2-foot-wide gated section with one Tainter gate, 14 feet high by 16 feet wide. The spillway section is 30-foot-long topped with 2-foot-high flashboards. The intake section is beneath the spillway with an earthen section containing a 30-foot-long retaining wall. The concrete and brick powerhouse houses one horizontal Francis turbine and General Electric generator combination with an installed capacity of 0.8 MW, along with appurtenant facilities.
The project operates in a store-and-release mode and impounds a 68-acre reservoir. There is no bypassed reach. The project relies on discharge from the upstream Oakland and Rice Rips projects. The project operates in a run-of-river mode when inflow is greater than 570 cfs and cycles when inflow is less than 570 cfs. The project provides a 15 cfs minimum flow and any water not passed through the turbines passes over the spillway. This minimum flow is based on historical leakage flow from Messalonskee Lake Dam as well as consultation with US Fish and Wildlife Service (USFWS).
Waters within the project reach are designated Category 2 – Rivers and Streams Attaining Some Designated Uses, Insufficient Information for Other Uses. In 2019, the project owner completed water quality sampling with consultation and approval from the Maine Department of Environmental Protection (MDEP). Sampling data was reviewed by MDEP and concluded that the project was not having an adverse effect on water quality in Messalonskee Stream.
Messalonskee Stream has historically been absent of anadromous fish due to limited rearing and spawning habitat, especially for those species currently subject to restoration efforts (alewife, American shad). Consultation with Maine Department of Marine Resources (MDMR) has also concluded that passage facilities are not warranted for species like Atlantic salmon and blueback herring which are present below the downstream Union Gas project. MDMR has prescribed passage facilities for American eel, for which the project installed an upstream ladder passage system. The passage system has been approved by both USFWS and MDMR. Upstream fish passage is facilitated by an eel ladder in place along the left abutment. Operation of the ladder is coordinated with MDMR and USFWS.
PLUS-Standard: The project owner voluntarily provides nighttime shutdowns at all four of its projects on Messalonskee Stream for American eel downstream passage, from 6pm to 2 am between September 1 to October 30. MDMR is currently collaborating with the project owner to adjust the timing of these shutdowns to better protect the migrating species. This action constitutes a basin-wide redevelopment strategy both within Messalonskee Stream and within the larger Kennebec River watershed where restoration of the diadromous fishery began with the removal of Edwards Dam at the head-of-tide in 1999 and allowed fish access to about 17 miles of river to Waterville, upstream of the Messalonskee Stream confluence. The Maine DMR issued the Kennebec River Management Plan Diadromous Resources Amendment in 2020, which updated a prior 1993 plan. The amendment includes American eel for the first time, with a stated goal “to provide safe, timely, and effective upstream and downstream passage for American eel throughout its historically accessible habitat.”
The project lands consist of less than 10 acres. There are no lands of significant ecological value in the project area due to its limited footprint.
Threatened or endangered species potentially present in the project vicinity include Northern long-eared bat, Atlantic salmon, and black term. The project area does not provide any suitable habitat for the bat species. Waterfowl surveys of the project area concluded that project operations do not impact habitat or nesting practices for the black tern. The species has been observed nesting in the Messalonskee Lake impoundment. According to USFWS, providing passage for Atlantic salmon in the Messalonskee watershed is not desirable.
The project powerhouse was constructed in 1924 and is eligible for listing on the National Register of Historic Places. The project owner consults with the State Historic Preservation Officer before conducting any non-routine maintenance projects on the powerhouse.
Recreational resources at the project include a fishing access point, a carry-in boat ramp, and a floating dock. The project owner collaborated with the City of Waterville to install the dock at the carry-in access point. Public access is provided free of charge.

May 22, 2017: On April 18, 2017, LIHI Executive Director Shannon Ames announced a Preliminary Certification Decision that the Automatic Hydroelectric Project (FERC No. P-2555) continues to satisfy the LIHI Certification Criteria. The certification includes three facility-specific conditions, as follows:
- Satisfied in 2019. Condition 1: The Owner shall complete water quality sampling during summer 2017 under a study plan approved in advance by the Maine Department of Environmental Protection (MDEP) and consistent with the MDEP’s Lakes, Ponds, and Impoundments Trophic State Study and Rivers and Streams Temperature and Dissolved Oxygen Study protocols. A copy of the final study plan shall be filed with LIHI within 30 days of MDEP approval. The results of the study report shall be filed with MDEP and LIHI by December 31, 2017. If the Automatic Project is determined to be causing, or contributing to, a violation of water quality standards, then a remediation proposal, including an implementation schedule, shall be developed in consultation with MDEP and filed with LIHI by April 1, 2018. If the project is found not to be causing or contributing to violations of water quality standards, then the Owner shall file review comments/recommendations from MDEP by the same date.
- Satisfied in 2021 with continued operation. Condition 2: The Owner shall continue to operate and maintain safe, timely, and effective upstream passage facilities for American eel at Automatic dam in coordination with the Maine Department of Marine Resources (MDMR) and the U.S. Fish and Wildlife Service.
- Satisfied in 2021 with continued operation. Condition 3: In the Owner’s Annual Compliance Statements, the Owner will update LIHI on the status of downstream eel passage at the site. The Owner will notify LIHI within 45 days if MDMR determines there is a sufficient number of eel present in the river to conduct the studies needed to determine the best location to install downstream passage. A summary of those study results, along with a MDMR-approved plan and schedule for downstream eel passage installation, shall be included in that year’s Annual Compliance Statement.
As provided for in Section 4.2.5 of the LIHI Handbook, notice of the preliminary decision to certify was posted on the Institute’s website and sent to this stakeholder email distribution list on April 21, 2017. A 30-day period was provided to anyone who commented on the original application to request an appeal, and no requests for appeal were received.
The Automatic Hydroelectric project is now deemed certified by LIHI for a 5-year term. The effective certification date for the Automatic Certificate is February 11, 2016, expiring on February 11, 2021.
April 21, 2017: On April 18, 2017, LIHI issued a Preliminary Certification Decision that the Automatic Hydroelectric Project (FERC No. P-2555) satisfies the LIHI Certification Criteria.
