The Slack Dam Project is located in Springfield, Vermont on the Black River. The presa is one of five existing concrete presas de gravedad on the Black River. The project is served by a 190 square mile drainage area on the Black River, 75% of which is controlled by the U.S. Army Corps of Engineers Flood Control Project in North Springfield, 4.5 miles upstream. Dams farther upstream include Cavendish (LIHI #97). Additionally, the Comtu Falls Project (LIHI #124) is located directly upstream and the Lovejoy Dam is directly downstream.

The project was reconstructed in 1986 and includes: a concrete presa de gravedad, central eléctrica, compuerta, and one horizontal Kaplan turbine with a capacity of 0.4 MW. The powerhouse is integral to the dam and constructed of reinforced concrete to an elevation greater than the 100-year flood level. A steel penstock 8 feet in diameter and 80 feet in length conducts water from the intake to the powerhouse.

El proyecto opera en un de pasada mode and impounds a 1-acre reservoir. The project provides a minimum flow of 0.5-inches of spillage over the crest of the dam. This flow regime was developed in consultation with the Vermont Department of Environmental Conservation (VDEC).

Waters within the project reach are designated as “Good” with the exception of a 2.5-mile stretch downstream just above the confluence with the Connecticut River as it is impaired for municipal sewer discharges.

Río abajo paso de peces is facilitated by a downstream chute cut into the dam along with a sluice and slide. This passage is now operated as requested by VDEC during the spring and fall seasons to protect resident fish species.

PLUS-Estándar: The project voluntarily operates its downstream fish passage from April 1 through June 15 and from September 15 through November 15 or as otherwise requested by state fisheries agencies.

The project lands consist of roughly 1 acre. The impoundment has some tree-lined shoreline, but the project is primarily surrounded by industrial buildings in the urban downtown of Springfield, VT. No lands of significant ecological value exist in the project area.

As confirmed by US Fish and Wildlife Service, there are not any federally or state listed species in the project area or downstream reach of the project.

Historical resources in the project area include the Slack Chimney, a National Register listed property. The project owner consults with the State Historic Preservation Office to ensure protection of the property.

Recreational resources at the project include pedestrian fishing access. Informal recreation also occurs at the project and is provided free of charge.
