Lake Blalock (formally, the H. Taylor Blalock Reservoir) is a reservoir in Spartanburg County, South Carolina, located on the Pacolet River about five miles north of Spartanburg. After its creation was authorized in 1976 by the Commissioners of Spartanburg Water System, Blalock Dam was constructed in 1983. The existing earthen dam is approximately 700 ft (210 m). long and 70 ft (21 m) high. It was originally designed for a normal operating pool of 700 feet (210 m), and the lake had approximately 35 miles (56 km) of shoreline. The existing spillway has a crest length of 270 ft (82 m).

To increase the safe yield of the reservoir, Spartanburg Water System raised the level of Lake Blalock by 10 feet (3.0 m), increasing the water surface elevation to 710 feet (220 m) in 2004. This project was completed in 2006 and involved overlaying the existing earthen dam with a layer of roller compacted concrete, approximately 3 ft (0.91 m) in thickness, and constructing a new RCC stilling basin. The existing spillway was also upgraded by furnishing and installing three hydraulically operated spillway crest gates, constructing a new cast-in-place concrete ogee crest, and constructing a bridge across the spillway. In addition, the project also cleared approximately 300 acres (42 miles of shoreline) around the perimeter of the reservoir.

Garrison Dam dam in McLean/Mercer Counties, North Dakota

Garrison Dam is an earth-fill embankment dam on the Missouri River in central North Dakota, U.S.. Constructed by the U.S. Army Corps of Engineers from 1947 to 1953, at over 2 miles (3.2 km) in length, the dam is the fifth-largest earthen dam in the world. The reservoir impounded by the dam is Lake Sakakawea, which extends to Williston and the confluence with the Yellowstone River, near the Montana border.

The Gatun Dam is a large earthen dam across the Chagres River in Panama, near the town of Gatun. The dam, constructed between 1907 and 1913, is a crucial element of the Panama Canal; it impounds the artificial Gatun Lake, which in turn carries ships for 33 kilometres (21 mi) of their transit across the Isthmus of Panama. In addition, a hydro-electric generating station at the dam generates electricity which is used to operate the locks and other equipment in the canal.

Dworshak Dam dam in Clearwater County, Idaho

Dworshak Dam is a concrete gravity dam in the western United States, on the North Fork Clearwater River in Clearwater County, Idaho. The dam is located approximately four miles (6 km) northwest of Orofino and impounds the Dworshak Reservoir for flood control and hydroelectricity generation. With a height of 717 feet (219 m), Dworshak is the third tallest dam in the United States and the tallest straight-axis concrete dam in the Western Hemisphere. Lacking fish ladders, Dworshak Dam blocks fish passage and completely extirpated anadromous fish migration into the upper reaches of the North Fork Clearwater River and its tributaries in Idaho. Construction of the dam by the U.S. Army Corps of Engineers (USACE) began in 1966 and was completed in 1973.

Saluda Dam dam in Lexington County, near Lexington, South Carolina

The Saluda Dam or Saluda River Dam, officially the Dreher Shoals Dam, commonly referred to as the Lake Murray Dam, is an earthen embankment dam located approximately 10 miles (15 km) west of Columbia, South Carolina on the Saluda River. Construction on the dam began in 1927 and was completed in 1930. The purpose of the dam is flood control, hydroelectricity, recreation and water supply. At the time of its completion, the Saluda Dam was the world's largest earthen dam, creating the world's largest man-made lake, Lake Murray. In 2005, construction on a 213 ft (65 m). tall roller-compacted concrete (RCC) dam was completed at the toe of the original dam in order to mitigate an earthquake-caused dam failure.

The Eklutna River is a 22-mile (35 km) long river located in the Southcentral region of the U.S. state of Alaska. A degraded anadromous stream of glacial origin, it originates at Eklutna Glacier and flows through Eklutna Lake and a canyon up to 350 feet (107 m) deep, emptying into the Knik Arm of Cook Inlet approximately 17 miles (27 km) northeast of Anchorage. It has one significant tributary, Thunderbird Creek, which enters the south bank about 1 km (0.6 mi) upstream from where the river exits the canyon and forms an alluvial fan. Due to water impoundments on the Eklutna River for power generation, Thunderbird Creek is currently the main source of water in the river. The river is located entirely within the limits of the Municipality of Anchorage.

Nottely Dam dam in Union County, Georgia, United States

Nottely Dam is a hydroelectric and flood storage dam on the Nottely River in Union County, in the U.S. state of Georgia. The dam is owned and operated by the Tennessee Valley Authority, which built the dam in the early 1940s as a flood control structure and to help regulate flow at nearby Hiwassee Dam. The dam impounds the Lake Nottely of 4,180 acres (16.9 km2). While the dam was built primarily for flood storage, a generator was installed at Nottely in the 1950s, giving it a small hydroelectric output.

Chatuge Dam dam in Clay County, North Carolina, United States

The dam impounds the 7,000-acre (2,800 ha) Chatuge Lake, which straddles the North Carolina-Georgia state line. While originally built solely for flood storage, a generator installed at Chatuge in the 1950s gives the dam a small hydroelectric output. The dam and associated infrastructure was listed on the National Register of Historic Places in 2017.
