The Newfound Hydroelectric project is located in downtown Bristol, New Hampshire approximately 800 feet downstream from the crossing of Water Street over the Newfound River. The area in the vicinity of the dam is urban in character and typical of an old New England manufacturing city. The project is located in the Merrimack River Basin approximately seven miles above the confluence of the Pemigewasset and the Winnipesaukee Rivers. The generally south flowing Merrimack River is New England’s fifth largest river. The basin is 134 miles in length and 68 miles wide. Total drainage area is 5015 square miles. The two principal headwater streams are the Pemigwasset River (accounting for 20% of the entire drainage) and the Winnipesaukee River. These streams join in Franklin, New Hampshire to form the Merrimack. The tributary with the second largest sub-basin is the Contoocook.

The land uses along the north side of the river to the east of the project’s diversion weir are predominantly industrial and to the west they are commercial. On the south side of the river the land usage to the east of the powerhouse is predominantly urban residential with commercial uses lying to the west. Along both banks above and below the dam the vegetation consists of planted ornamentals and those types typical of disturbed ground.
The facility is operated as a fully automated run of river project. At times of non-generation, the project is licensed to release an outflow equal to an instantaneous minimum of 5 cfs. When inflows fall below 5 cfs, inflow is equal to outflow. The licensee is responsible for maintaining a continuous minimum flow of 5 cubic feet per second or the inflow to the project’s diversion weir, whichever is less, for the protection and enhancement of aquatic resources in the river. The Newfound Project discharges into the Pemigewasset River, seven miles above its confluence with the Winnipesaukee River. Historical river flows in the Pemigewasset River within the project area are 151 cfs.
Construction of the Newfound hydroelectric project was completed in 1927. Project works consist of: (a) a diversion weir surmounted by wooden flashboards, totaling 10 feet in height; (b) a 0.23-acre reservoir with a storage capacity of 0.69 acre-feet; (c) a concrete intake channel; (d) a powerhouse containing two generating units (870 kW and 617 kW); a 6-foot diameter wooden penstock 420 feet long; (f) a 30-foot wide tailrace extending 175 feet to the confluence of the Newfound and Pemigewasset Rivers; (g) a 160-foot-long underground cable from the powerhouse to an existing pole of the power purchaser, Public Service Company of New Hampshire; and (h) appurtenant works.
On November 6, 1981 the Federal Energy Regulatory Commission (“FERC”) issued a minor license to the Newfound Hydroelectric Company (Licensee) of Bristol, New Hampshire, under part I of the Federal Power Act, for a period of fifty years (FERC 3107, see Appendix 1-1). The project works consist of: (1) a diversion weir located adjacent to New Hampshire Route 3A in Bristol, New Hampshire; (2) a new 800-footlong water conveyance facility, leading to (3) a new powerhouse located approximately 800 feet downstream of the Water St. Bridge; and (4) appurtenant works. The installed capacity of the project is 1,500 kW.
November 2, 2017: On October 29, 2017, the 30-day appeal window for the preliminary decision to recertify the Newfound Hydroelectric Project ended with no appeals filed. The recertification decision is therefore final.
The term of Low Impact Certification for the Newfound Hydroelectric Project is from May 13, 2016 and expires on May 13, 2021.
September 29, 2017: The Low Impact Hydropower Institute has issued a Preliminary Certification Decision that the Newfound Hydroelectric Project continues to satisfy the LIHI Certification Criteria. The Certification includes four facility specific conditions, as follows:
Condition 1: The Owner shall complete a water quality sampling study during summer 2018 under a study plan approved in advance by the New Hampshire Department of Environmental Services (NHDES). The study plan shall be filed with NHDES no later than December 31, 2017. A copy of the final study plan shall be filed with LIHI within 30 days of NHDES approval. The data and study report shall be filed with NHDES and LIHI by December 31, 2018. If the Newfound Project is determined to be causing, or contributing to, substandard water quality, a remediation proposal, including an implementation schedule, shall be developed in consultation with NHDES and filed with LIHI by April 1, 2019. Otherwise, the Owner shall file review comments and/or recommendations from NHDES by the same date.
Condition 2: The Owner shall continue to maintain a minimum flow of 12.7 cfs, or instantaneous inflow if less, through the penstock-bypassed reach of river for the duration of this new LIHI certification.
Condition 3: The Owner shall continue to maintain systems and protocols necessary to assure compliance with the headpond elevation and flow management limitations of instantaneous run-of-river operation and the release of a minimum bypass flow as specified in Condition No. 2 and to maintain records demonstrating compliance that may be provided to LIHI if requested.
Condition 4: If a fisheries agency requests or prescribes upstream or downstream fish passage at the Project during the term of the new LIHI certificate, the Owner shall notify LIHI within 30 days of such action and the steps that the Owner is prepared to take to install appropriate passage at the Project dam. In the event that the Owner notifies LIHI that it does not intend to install appropriate passage, or that the Owner cannot reach an agreement with the resource agency, or agencies, as to the nature of this passage, LIHI reserves the right to withdraw its certification should LIHI determine that the Owner’s position is inconsistent with the LIHI fish passage criteria at that time.
Comments that are directly tied to specific LIHI criteria (flows, water quality, fish passage, etc.) will be most helpful, but all comments will be considered. Comments may be submitted to the Institute by e-mail at email@example.com with “Newfound Project Comments” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, 329 Massachusetts Ave, Suite 2, Lexington, MA, 02420. Comments must be received at the Institute on or before 5 pm Eastern time on October 29, 2017 to be considered. All comments will be posted to the web site and the applicant will have an opportunity to respond. Any response will also be posted. Once final, the effective certification date for the Newfound Hydroelectric Project is May 13, 2016 for a five (5) year term which will expire on May 13, 2021.Once final, the effective certification date for the Newfound Hydroelectric Project is May 13, 2016 for a five (5) year term which will expire on May 13, 2021.
The Newfound comment period has been extended to February 10, 2017.
December 8, 2016: The Low Impact Hydropower Institute has received a complete application for a new term of Low Impact Certification for the Newfound Hydroelectric project. The application materials can be found in the Files section below.
LIHI is seeking public comment on this application. Specifically, we are interested in knowing whether you think the Newfound project meets the LIHI Low Impact Certification Criteria, as revised in the 2nd Edition Handbook released in March 2016. Please review the program and criteria in LIHI’s revised Handbook and then review the Project’s 2016 application materials posted on the project page.
