Prado Dam: Prado Dam is an earth-fill dam across the Santa Ana River at the Chino Hills near Corona, California in Riverside County with the resulting impounded water creating Prado Flood Control Basin reservoir.  The U.S. Army Corps of Engineers built the dam in Lower Santa Ana River Canyon.  Its primary purpose is flood control and it is the downstream element of the Santa Ana River's flood control system, which is a natural constriction about 30.5 mi upstream from the ocean.  The area upstream from the dam contains 2255 sqmi of the watershed's 2650 sqmi .  The dam's construction was authorized in 1936 and the flood of 1938 demonstrated its necessity.  Construction was completed in 1941.  Prado Flood Control Basin also provides water storage for groundwater recharge operations.

U.S. Route 27 in Kentucky: U.S. Route 27 (US 27) in Kentucky runs 190.785 miles from the Tennessee border to the Ohio border at Cincinnati, Ohio.  It crosses into the state in the Lake Cumberland area, passing near or through many small towns, including Somerset, Stanford, Nicholasville.  The road then passes straight through the heart of Lexington, including directly past University of Kentucky and Transylvania University.  North of Lexington it passes through Cynthiana and Falmouth before entering Campbell County and passing through many Northern Kentucky suburbs before ending at the Ohio state line on the Taylor Southgate Bridge in Cincinnati.

Jiangpinghe Dam: The Jiangpinghe Dam （） is a concrete face rock-fill embankment dam on the Loushui River near Jiangpinghe village, Zouma Town, in Hefeng County in Hubei Province, China.  The purpose of the dam is hydroelectric power generation, flood control and irrigation.  The dam houses a hydroelectric power station with 2 x 250 MW generators for a total installed capacity of 500 MW.  Its expected generation of 1005 GWh will be transferred to the Central China Power Grid.  Construction on the dam began in 2005 and the first generator went online in July 2012.  The dam is 221 m tall, withholding a 1366000000 m3 reservoir of which 787000000 m3 is active or "useful" storage.

Lake Cumberland: Lake Cumberland is a reservoir in Clinton, Laurel, McCreary, Pulaski, Russell, and Wayne counties in Kentucky.  The primary reasons for its construction were a means for flood control and the production of hydroelectric power.  Its shoreline measures 1,255 miles (2,020 km) and the lake covers 65,530 acre at the maximum power pool elevation.  The reservoir ranks 9th in the U.S. in size, with a capacity of 6100000 acre.ft of water, enough to cover the entire Commonwealth of Kentucky with 3 inches (76 mm) of water.  The main lake is 101 mi long and over one mile (1.6 km) across at its widest point.

Grančarevo Dam: The Grančarevo Dam is an arch dam on the Trebišnjica River near Gornje Grančarevo in the municipality of Trebinje in Bosnia and Herzegovina.  At 123 m in height, it is the tallest dam in the country.  Its reservoir, Bileća Lake, is the largest by volume in Bosnia and Herzegovina as well.  The dam provides for flood control and hydroelectric power generation.  The dam was completed in 1967 and its 180 MW power station, Trebinje-1 (Čapljina) Hydroelectric Power Station, was commissioned in 1968.  A smaller 8 MW power station, Treblinje-2, was completed downstream in 1979.

Narrows Dam: Narrows Dam is a dam located 6 miles north of Murfreesboro, Arkansas, that impounds the water of the Little Missouri River (Arkansas) to create Lake Greeson.  Narrows Dam was authorized as a flood control and hydroelectric power project by the Flood Control Act of 1941.  The dam is a feature of the comprehensive plan for the Ouachita River Basin.  Lake Greeson is operated for hydroelectric power, recreation, and flood control.  

Fort Gibson Dam: The Fort Gibson Dam is a gravity dam on the Grand (Neosho) River in Oklahoma, 5.4 mi north of Fort Gibson.  The purpose of the dam is flood control and hydroelectric power production.  It was authorized by the Flood Control Act of 1941 and construction began the next year.  During World War II construction was suspended and it recommenced in May 1946.  In June 1949, the river was closed and the entire project was complete in September 1953 with the operation of the last of the power plant's four generators.  The dam and power rights originally belonged to the Grand River Dam Authority but were seized by the U.S. Army Corps of Engineers in 1946.

Ilısu Dam: The Ilısu Dam (] ) is a concrete-face rock-fill dam under construction on the Tigris near the village of Ilısu and along the border of Mardin and Şırnak Provinces in Turkey.  It is one of the 22 dams of the Southeastern Anatolia Project and its purpose is hydroelectric power production, flood control and water storage.  When complete, the dam will support a 1,200 MW power station and will form a 10.4 billion m reservoir.  Construction of the dam began in 2006 and it is expected to be complete by 2016.  As part of the project, the much smaller Cizre Dam is to be constructed downstream for irrigation and power.  The dam has drawn international controversy, because it will flood portions of ancient Hasankeyf and necessitate the relocation of people living in the region.  Because of this, the dam lost international funding in 2008.  Kurdish militants have also attacked infrastructure associated with the dam which has led to construction delays.

Yingzidu Dam: The Yingzidu Dam is a concrete-face rock-fill dam on the Sancha River, a tributary of the Wu River, in Pingba County of Guizhou Province, China.  The purpose of the dam is hydroelectric power production and flood control.  It supports a 360 MW power station located just downstream.  At a normal elevation of 1086 m the reservoir withholds 455000000 m3 but it can hold up to 531000000 m3 in the event of a flood.  The spillway on the dam can also discharge up to 8386 m3/s of water.  Construction on the dam began on 8 November 2000 and on 10 April 2003 it began to impound its reservoir.  On 22 May of the same year the first generator was commissioned, the second in August.  By June 2004, the project was complete.

Nuozhadu Dam: Nuozhadu Dam () is an embankment dam on the Lancang (Mekong) River in Yunnan Province, southwest China.  The dam is 261.5 m tall, and creates a reservoir with a normal capacity of 21749000000 m3 at a level of 812 m asl.  The purpose of the dam is hydroelectric power production along with flood control and navigation.  The dam supports a power station with nine generators, each with generating capacity of 650 MW.  The total generating capacity of the power station is 5,850 MW.  Construction on the project began in 2004; the dam's first generator went online 6 September 2012 and the last generator was commissioned in June 2014.  The construction and management of the project was implemented by Huaneng Power International Ltd., which has a concession to build, own and operate hydroelectric dams on China's stretch of the Mekong River.
