The lake covers nearly 14,000 acres (57 km 2) with 190 miles (310 km) of shoreline touching three counties. [6] The lake is an average of 23 feet (7.0 m) deep with an estimated volume of 1.35 × 10 10 cubic feet (3.82 × 10 8 m 3 ).
Less onerous breadth and depth regulations exist for lesser swimming competitions, but any "long course" event requires a course length of 50 metres (164 ft 0.5 in), as distinct from "short course" which applies to competitions in pools that are 25 metres (82 ft 0 in) in length (or 75 feet (22.9 m) in the United States). If touch pads are used ...
The Great Lakes contain 21% of the world's surface fresh water: 5,472 cubic miles (22,810 km 3), or 6.0×10 15 U.S. gallons, that is 6 quadrillion U.S. gallons, (2.3×10 16 liters). The lakes contain about 84% of the surface freshwater of North America; [ 48 ] if the water were evenly distributed over the entire continent's land area, it would ...
In 1912 (113 years ago) () a 72 ft (22 m) multiple arch dam was constructed about 300 ft (91 m) downstream of the old dam and increased the lake capacity to 73,000 acre-feet (90,000 dam 3). The original granite dam still remains, usually under about 20 feet of water. A highway bridge (SR 18) was built over the arches of the new dam in 1923.
Water levels in the years 1887–2019.

Mount Rushmore attracts more than two million visitors annually [1] to the memorial park which covers 1,278 acres (2.00 sq mi; 5.17 km 2). [7] The mountain's elevation is 5,725 feet (1,745 m) above sea level. [8] Borglum chose Mount Rushmore in part because it faces southeast for maximum sun exposure.
The combined volume of water in all the oceans is roughly 1.335 billion cubic kilometers (1.335 sextillion liters, 320.3 million cubic miles). [ 74 ] [ 93 ] [ 94 ] This section is an excerpt from Hydrosphere .
