Devil's Gate-Weber Hydroelectric Power Plant, Hydroelectric power plant district in Weber Canyon, US.

The Devil's Gate-Weber Hydroelectric Power Plant is a brick powerhouse with a gabled concrete roof on riveted steel Fink trusses, built 1909–1910 in Weber Canyon. Water arrives through a 74-inch reinforced concrete and welded steel conduit from a low dam 1.75 miles upstream, driving a Pelton wheel turbine and a 2300-volt Western Electric generator. The intake house and a wood-frame watchman's house stand just downstream.

The facility was built in 1910 by Utah Light and Railway Company and ranked among the first power plants to connect to an electrical grid in Utah. The project became central to electrifying the region and powering surrounding communities and railway operations.

The operator's camp once had four houses, not a four-family settlement community; two survive, a one-story brick house and a 1922 wood cottage, both keeping landscaping and garden areas with outdoor fireplaces. The powerhouse's main room holds a Pelton wheel turbine and a 2300-volt Western Electric generator, with a 20-ton Whiting Foundry traveling crane serving the turbine room.

The powerhouse and its remaining operator houses stand in Weber Canyon between the lanes of Interstate 84, about 10 miles southeast of Ogden; the westbound lanes pass just north of the buildings. The intake conduit crosses the river on a 99-foot riveted steel Howe truss bridge downstream from the dam, and the dam itself lies about 1.75 miles upstream. The structures are visible from the highway, but there is no separate visitor access described.

The power plant spreads across two counties, with the powerhouse in Weber County while the dam reaches into Morgan County. This is an unusual example of infrastructure intentionally crossing administrative boundaries.
