The Open Square Project is located in Holyoke, Massachusetts on the Connecticut River and the Holyoke Canal System, a man-made structure constructed for the purpose of power generation. The canal system consists of three levels, referred to as First, Second, and Third Level Canals. Holyoke Gas & Electric (HG&E), a department of the City of Holyoke owns and operates hydroelectric facilities at Holyoke Dam (the Hadley Falls Station) and in the Holyoke Canal System (LIHI #89).
There are 16 hydroelectric generating stations currently in service on the Holyoke Canal System including two owned by Open Square and 14 owned and operated by HG&E. The canal system begins with the canal gatehouse structure located between the Hadley Falls Station and the western shore. The dam and canal system were conceived and constructed by the South Hadley Falls Company starting in 1847. The first mills were built and operated in 1848 and the first hydroelectric turbine was installed in the system in 1888.
Open Square is a mixed-use development of seven historic mill buildings containing 685,000 square feet of floor area on an 8-½ acre city block located between the First and Second Level Canals of the HG&E hydropower system. The project occupies a small amount of space within the complex.
The Canal System begins at a gatehouse structure located directly upstream of Hadley Falls Station. The Open Square project consists of two powerhouses each with single units, referred to as the D-Wheel and the G-Wheel. The D-Wheel powerhouse is located in the northeast corner of the lower level floor of Mill 2 at Open Square. The D-Wheel unit consists of a Leffel 33-inch ‘Z’ Vertical Francis Turbine in a pressure flume with an Electric Machine Company synchronous generator installed in 1933. The unit has a capacity of of 260 kW. The G-Wheel powerhouse is located in the northwest corner of the lower level floor of Mill 5. The unit consists of a Leffel 33-inch ‘Z’ Vertical Francis Turbine in a pressure flume with a General Electric synchronous generator installed in 1928 and has a capacity of 280 kW.
The project is a conduit facility and operates in a run-of-river mode. The project inflow is maintained at a constant elevation except for annual maintenance drawdown.
Waters within the project reach are designated as impaired for PCBs, E. coli, and total suspended solids. The project does not have any independent control over water quality in this reach. Water quality is monitored for temperature, dissolved oxygen, and fecal coliform by HG&E. The Massachusetts Department of Environmental Protection confirms that the project is not the cause of the listed impairments.
Migratory fish are excluded from the canal system and passage systems at the Hadley Falls Dam facilitate upstream fish migration in the Connecticut River. This consists of a fish lift and upstream eel ramps used to pass diadromous species upstream. Downstream passage is facilitated by a louver facility located about 554 feet downstream of the canal gatehouse. The full-depth louver rack is angled downstream across the canal and ends at a bypass facility and pipe. The pipe transports migrating fish to the Hadley Falls Station tailrace. The No. 1 Overflow structure, which is located immediately downstream of the gatehouse, discharges water directly back to the Hadley Falls Station tailrace, or to the fish lift attraction water. The Massachusetts Division of Fisheries and Wildlife confirms that the passage prescription works effectively and that passage facilities are not need at the Open Square project.
The project lands under the control of the owner only include the 8.5-acre mill site. No lands of significant ecological importance exist in the project vicinity as the surrounding area is urban streets and canals.
Threatened or endangered species potentially present in the project vicinity include yellow lampmussel and dwarf wedgemussel. The only potential for impact on listed species comes during maintenance drawdowns in the canal system. HG&E has implemented protocols during drawdown periods to minimize impact on the listed species as approved by resource agencies.
The Holyoke Canal system is listed on the National Register of Historic Places as a Historic District and the project site is included in the Inventory of Historic and Archaeological Assets of the Commonwealth of Massachusetts. The project owner provides site tours of the mill buildings and turbines and hosts performances of local historical plays.
While recreational access is limited for public safety concerns, the project owner is undertaking enhancement activities on the property including new sidewalks and a Canal Walk with pedestrian lighting, trees, and bike lanes. The project also collaborates with the town to plan activities on the Canal Walk.
