The category lists dams constructed primarily with roller-compacted concrete (RCC). They include arch and gravity dams currently proposed, under construction or completed. Contents
The rebuilt upper reservoir of the Taum Sauk plant, nearing completion in this photo, is the largest RCC dam in North America. [1]Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for portland cement.

I looked up this article because roller-compacted concrete will be used in major repair work at the Oroville Dam. These comments are on the 12/27/16 version of this article. This article cites the following: Abdo, Fares (2008). "RCC Trends in Early 21st Century Medium-Size Dams" (PDF). HydroVision 2008.
Roller gates of Mississippi River Lock and Dam No. 15, the largest roller dam in the world. Roller dams are a type of weir, or a dam that is designed to allow water to flow over the top in continuous action. They are used on rivers or other such moving bodies of water where erosion damage is undesirable, yet likely to occur.
The San Roque Dam, operated under San Roque Multipurpose Project (SRMP) is a 200-meter-tall, 1.2-kilometre (0.75 mi) long embankment dam on the Agno River. It is the largest dam in the Philippines and sixteenth largest in the world (see List of largest dams in the world ).
Ciriaco Nadres in 1872 constructed a dam made of adobe to irrigate his farms. His property was later sold to Placido Escudero in 1890. The dam was later enhanced in 1904 using concrete and expanded in 1937 to generate 90 KVA electricity for communities in Quezon, making it the first mini-hydroelectric dam in the Philippines.
A combination of design and construction flaws, continuing to operate the dam when the primary system for gauging the water level was known to be inaccurate (gauge pipes had become detached), moving the "failsafe" secondary gauging system above the actual height of the dam to avoid false positives, and operating the dam in an unsafe manner by ...
Willow Creek Dam in Oregon, a roller-compacted concrete gravity dam. A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation. Gravity dams are designed so that each section of the dam is stable and independent of any ...
