Barragem de Varosa

By jbottero

(2026-07-08)

In Portugal, the Varosa dam was built on a small tributary of the Douro River. The concrete vault is best known for its impressive staircase built in terraces, allowing the natural rock and the structure of the dam to merge.

Varosa Dam is an arched concrete dam with a height of 76m above the natural terrain. The length of its crown is 213 m long and 3.44 m wide making it one of the smallest hydroelectric power plants in Portugal.

What makes it remarkable, however, is probably its monumental maintenance access staircase on its west end. These stairs are arranged on a succession of concrete terraces that form a buffer between the dam to its right and the natural rock to its left.

Seminoe Dam is a concrete thick-arch dam on the North Platte River in the U.S. state of Wyoming. The dam stores water for irrigation and hydroelectricity generation and is owned and operated by the U.S. Bureau of Reclamation. It is the uppermost dam on the North Platte River and is located directly upstream from the Kortes Dam. It lies in a narrow, isolated canyon formed by the North Platte cutting through the Seminoe Mountains about 40 miles (64 km) northeast of Rawlins. The 295-foot (90 m) dam forms Seminoe Reservoir, which covers more than 20,000 acres (8,100 ha) when full. Seminoe State Park is adjacent to the reservoir. The small village of Seminoe Dam abuts the dam and reservoir and provides residence for the dam attendants and park services personnel.

Guernsey Dam

By Matheus_

(2025-05-18)

Guernsey Dam is an earthfill dam on the North Platte River in Platte County in the U.S. State of Wyoming. The dam creates Guernsey Reservoir, the last of the 5 major reservoirs on the North Platte River in Wyoming. The dam contains a hydroelectric plant capable of 6.4 megawatts of electricity. The total capacity of the reservoir is 71,040 acre-feet (87,630,000 m3) of water which is used mainly for irrigation. Morrison-Knudsen (Now URS Corporation) and Utah Construction Company constructed Guernsey Dam and the hydroelectric plant as part of the North Platte Project to provide irrigation to eastern Wyoming and western Nebraska. Guernsey helps control the river flow and stores water released from the project's primary storage upstream at Pathfinder Reservoir. About 8 miles (13 km) downstream of the dam the Whalen Diversion Dam diverts water into the Fort Laramie and Interstate Canals that service farms in Wyoming and Nebraska.

The reservoir is surrounded by Guernsey State Park.

Glendo Dam

The earthfill dam is 2,096 feet (639 m) feet long and 190 feet (58 m) high and contains two hydroelectric turbines capable of generating 38 megawatts of power.The reservoir retains a maximum of 1,170,505 acre-feet (1.443797×109 m3) of water used primarily for irrigation and flood control.

Pathfinder Dam

By Matheus_

(2025-05-18)

Pathfinder Dam is a masonry dam, located on the North Platte River, approximately 47 miles (76 km) southwest of Casper, Wyoming. It was constructed from 1905 to 1909 as part of the North Platte Project and has been modified several times since then. It is included on the National Register of Historic Places. Construction of the dam created Pathfinder Reservoir which provides water storage for 226,000 acres (910 km2) of irrigation in Wyoming and Nebraska. The dam is named for General John Charles Fremont, who had explored the area in 1842 and was nicknamed the "Pathfinder of the West."

Fontenelle Dam

By Matheus_

(2025-05-11)

Fontenelle Dam was built between 1961 and 1964 on the Green River in southwestern Wyoming. The 139-foot (42 m) high zoned earthfill dam impounds the 345,360-acre-foot (0.42600 km3) Fontenelle Reservoir. The dam and reservoir are the central features of the Seedskadee Project of the U.S. Bureau of Reclamation, which manages the Fontenelle impoundment primarily as a storage reservoir for the Colorado River Storage Project. The dam suffered a significant failure in 1965, when the dam's right abutment developed a leak. Emergency releases from the dam flooded downstream properties, but repairs to the dam were successful. However, in 1983 the dam was rated "poor" under Safety Evaluation of Existing Dams (SEED) criteria, due to continuing seepage, leading to an emergency drawdown. A concrete diaphragm wall was built through the core of the dam to stop leakage.

Cushman Dam No. 1

By Matheus_

(2024-12-27)

Cushman Dam No. 1 is a hydroelectric dam on the North Fork of the Skokomish River in Mason County, Washington, which in derogation of the natural and treaty rights of the Native inhabitants impounded and enlarged the formerly natural Lake Cushman, leading to damage claims in excess of $5 billion and an eventual settlement agreement with the Skokomish tribe that terminates the right to operate the dam(s) after 2048. It was built by Tacoma City Light (now Tacoma Power) in 1924–1926. Tacoma's demand for electricity grew rapidly after World War I. Tacoma City Light's Nisqually River Hydroelectric Project, built in 1912, could not meet the demand and the utility decided to build a new hydroelectric project on the North Fork Skokomish River. The dam and powerhouse first began to deliver electricity on February 12, 1926.

The Safe Harbor Dam (also Safe Harbor Hydroelectric Station) is a concrete gravity dam, with an associated hydroelectric power station, on the lower Susquehanna River. It is the most northerly and last of three Great Depression-era public electrification projects' hydroelectric dams, and was constructed between April 1, 1930, and December 7, 1931. It created a long and relatively shallow lake, known as Lake Clarke, along the upper stretch of the Conejohela Valley. The creation of the lake shrank the upper Conejohela Flats in size.

Two of the turbine units are dedicated to generating for Amtrak's 25 Hz traction power system, and the facility also has a frequency converter available for conversion of power between 25 Hz and the 60 Hz used by the electric grid.
