Remains of the Band-e Kaisar dam, built by the Romans in the 3rd century AD. In Iran, bridge dams such as the Band-e Kaisar were used to provide hydropower through water wheels, which often powered water-raising mechanisms. One of the first was the Roman-built dam bridge in Dezful, [24] which could raise water 50 cubits (c. 23 m
The Laguna Dam's design and size made it a peculiar structure for the time. The dam, a weir, was merely 43 ft. tall, almost two-thirds of which were built below the riverbed. Subsequently, the dam only raised the river ten feet. Modifications to the dam's downstream talus were done between 1923–1924. [2]
This dam was renamed Ross Dam after the death of James Delmage Ross (1872–1939), the superintendent of the Skagit River Project.

The dam (marked as Juneau B-2 in USGS maps) is located at the terminus of the tram-way that was built specifically by the Alaska Gastineau Mining Co.
But most of these dams were built between the 1930s and 1960s, and some are now beyond their useful lives. Today, we understand dams compromise entire ecosystems. We have better ways to reap the ...
The dam was built by the U.S. Army Corps of Engineers between 1946 and 1954 for the purposes of flood control, hydroelectricity and downstream navigation. The concrete structure of the dam spans 1,096 feet (334 m) and rises 204 feet (62 m) above the riverbed, housing a power plant with an installed 380 MW capacity. The Dam has prevented over $3 ...
