Taylors Falls in Chisago County, Minnesota — The American Midwest (Upper Plains)
Saint Croix Falls Hydroelectric Project
“'Something is doing’ that may be quite important.”
This stretch of the river had high traprock banks and a dramatic drop, the perfect makings for a hydroelectric project. Completed in 1907, the dam is an early example of a concrete-arch gravity dam. This type of structure combines features of gravity and arch dams. Gravity dams use their own weight to retain water, while arch dams curve to direct forces outward. Arch dams were ideally suited for areas where thick rock walls could absorb the thrust of the water. The traprock ledge likely influenced the decision to use an arch in this location.
Efficiency typically governed the design of powerhouses. Most were simple box-like buildings with few architectural details. As one of the largest hydroelectric projects in the region, and because of its location in a popular scenic area, the station here featured arched window openings. The openings were later filled, but they continue to enhance the building's appearance. The plant had the capacity to develop 25,000 horsepower, although
Several features were incorporated into the dam, which is about 750 feet long. A log spillway is at the western end and a fish ladder is on the east. The dam produced a head of about 56 feet. This was bolstered by a concrete dike to the west that helped raise the water level and protected Taylors Falls from flooding. The dam and dike also provided recreational benefits by pooling the water upstream. "This lake will increase immensely the attractiveness of the park region," noted one journalist. "Boat and club houses will be erected and it is expected that Taylors Falls will speedily become one of the most popular summer resorts in the west."

1. Saint Croix Falls Dam. Once the logging era was nearly played out, Northern States Power gained rights to the falls. They constructed the concrete arched dam that we see today. It has a 675 foot long arched dam 59 feet tall, one wide gate that serves both as a log sluice and overflow gate, a power plant that is 291 feet wide, and a secondary dike on the Minnesota side that is 785 feet long. The dam went on-line in 1907. It produces 25-megawatts of (Submitted on July 18, 2018, by Cosmos Mariner of Cape Canaveral, Florida.)
2. St. Croix Falls Hydro Generating Station. The St. Croix Falls Hydro partial peaking plant is the only existing dam on the St. Croix River. The plant was built to provide electricity for the Twin Cities. Construction involved hundreds of laborers who worked day and night shifts seven days a week. For two years, blasting shook buildings and shattered windows in St. Croix Falls and in Taylors Falls, MN just across the river. The spillway provides a scenic view from overlooks on both the Minnesota and Wisconsin sides of the river. A feature that separates the St. Croix Falls plant from other hydroelectric units is its "S" shaped spillway. The spillway was constructed as a curve to increase its crest area, since the river at that spot forms a gorge through which passes a large volume of water.
