The Macomb Project is the most downstream hydroelectric project on the “North” Salmon River (not to be confused with the Salmon River in Oswego County) in the Town of Malone in Franklin County, New York. From its cabeceras in the Adirondack Mountains, the river flows approximately 50 miles northwest to its confluence with the St. Lawrence River near Dundee, Quebec. The Project was originally constructed in 1899 for the sole purpose of energy production. A second central eléctrica was built in 1904 (High Falls No. 2) upstream of the original powerhouse which was subsequently retired in 1940. Several improvements were made between 1940 and 1987. There are several other dams on the Salmon River including the Mountain View Project, Chasm Project (LIHI #158), Ballard Mill, and Whittelsey Project, all upstream of Macomb.

El proyecto incluye: a presa, integrated aliviadero, compuerta, two intake structures, powerhouse, tubo de tiro, and one turbine.

The dam is a concrete gravity overflow-type, 106 feet long and 32 feet high. Two stone intake structures are capped with concrete, one located at each end of the dam, positioned 90 degrees to the spillway. The intake structure on the right bank of the river (looking downstream) consists of a manually-operated steel slide gate at the upstream end of a 6-foot-diameter pipe that discharges immediately downstream of the dam. The 38-foot-long, 25-foot-high intake structure along the left bank of the river has a manually-operated steel slide gate. When open, flow passes through the gate to a 6.5-foot-diameter, 60-foot-long gated riveted steel penstock that leads to the powerhouse. The water intake has trashracks with 1-inch clear spacing on a year-round basis. The powerhouse contains a single horizontal Francis unit with an installed capacity of 1.0 MW. The intake and penstock create a short bypassed reach, approximately 100 feet long.

The project impounds a 14-acre impoundment known as Lamica Lake. The project is operated in a pulsing mode when river flow exceeds 125 cfs. Efforts are made to maintain impoundment fluctuations within 0.25‐foot of the dam crest. The project operates in run‐of‐river mode when river flows are 125 cfs or less. This flow regime was developed in consultation with USFWS and the New York State Department of Environmental Conservation (NYSDEC).

Waters in the project reach are designated as Class C waters best used for fishing, fish propagation, and primary/recreación secundaria where appropriate. The project operates under a sediment management plan which aims to minimize the potential for sediment releases that could impact habitat and populations downstream.

The project is located at the site of a natural falls that has historically created a hydraulic barrier, preventing pez anádromo from passing by the project. Though the Salmon River once supported freshwater runs of walleye, muskellunge, and northern pike, the present fish community in Lamica Lake consists of warm-water fish species such as bass and bullhead, as well as brown and rainbow trout, present via stocking. The US Department of the Interior has no plans for a paso de peces prescription for the project. Trashracks with 1-inch spacing prevent arrastre and a fish stocking tube allows the NYSDEC to stock trout directly into the tailrace.

The project lands consist of roughly 9 acres. Land uses in the project vicinity are primarily low density residential, commercial, recreation, agriculture, and forestry. The impoundment fluctuation limit of 0.25 feet helps to minimize erosion potential and protect humedal, ribereño, and littoral habitat in the project vicinity. The project also conducts sediment flushing procedures when inflows exceed 700 cfs at the upstream Chasm Project.

Threatened or endangered species potentially present in the project vicinity include the Northern long-eared bat. Based on consultation with the NYSDEC’s Natural Heritage Program, there are no critical habitats or records of listed species in the project area. Operations at the project must comply with the USFWS 4(d) rule concerning the protection of the northern long-eared bat which restricts tree clearing activities from June1 – July 31.

Historic properties in the project area include the High Falls No.1 powerhouse ruins as well as the project dam, powerhouse, gatehouse, and intakes. The project owner collaborated with the State Historic Preservation Office (SHPO) to develop mitigation measures to ensure cultural and historic resources were properly preserved. Embargo fluctuation limits help mitigate any impacts and the project submits annual reports to the SHPO on any activities pertinent to resource stewardship.

Recreational resources in the project area include a car-top boat launch, a downstream angler access trail, shoreline fishing area, and a recreational trail. Public access is provided free of charge.
