Title: List of largest lakes of the United States by volume
Content:  This article lists the largest lakes, natural and man-made, in the United States by volume -- the amount of water they contain under normal conditions. Volumes given for lakes shared with Canada and Mexico are for the total volume of the lake. Many lakes vary substantially in volume over time, especially man-made lakes, reservoirs, and lakes in arid areas. Capacity given is for normal or average lake level. Note: Volume estimates not available for Selawik and Naknek Lakes in Alaska. They would undoubtedly rank on this list if data available.

Title: Lake of the Ozarks
Content:  them. At the time of construction, Lake of the Ozarks was the largest man-made lake in the United States and one of the largest in the world. It was created to provide hydroelectric power for customers of Union Electric, but it quickly became a significant tourist destination. Most of its shoreline is privately owned, unlike many flood-control lakes in the region that were constructed by the U.S. Army Corps of Engineers. The relatively stable surface elevation has created conditions suitable for private development within a few feet of the shoreline. There are over 70,000 homes along the lake, many of which are vacation homes. The lake is now a major resort area, and more than 5 million 
Title: Lake Sakakawea
Content:  Lake Sakakawea is a large reservoir in the north central United States, impounded in 1953 by Garrison Dam, a U.S. Army Corps of Engineers dam located in the Missouri River basin in central North Dakota. Named for the Shoshone-Hidatsa woman Sakakawea, it is the largest man-made lake located entirely within the State of North Dakota, the second largest in the United States by area after Lake Oahe, and the third largest in the United States by volume, after Lake Mead and Lake Powell. The lake is located about 50 mi from the state capital of Bismarck; the distance by the Missouri River is about 75 mi. The lake averages between 2 – in width and is 14 mi wide at its widest point (Van Hook Arm). Lake Sakakawea marks the maximum southwest extent of glaciation during the ice age. The lake is located within the counties of: Dunn, McKenzie, McLean, Mercer, Mountrail, and Williams.
Title: List of largest lakes of the United States by area
Content:  The following is a list of the 100 largest lakes of the United States by normal surface area. The top twenty lakes in size are as listed by the National Atlas of the United States, a publication of the United States Department of the Interior. The area given is the normal or average area of the lake. The area of some lakes fluctuates substantially. For those lakes partially in Canada or Mexico the area given for the lake is the total area, not just the part of the lake in the United States. Of the top 100 lakes, 55 are man-made and 45 are natural. Three lakes in the top 100 are primarily salt water.
Title: Glen Canyon Dam
Content:  With a capacity of 27 e6acre feet, Lake Powell is the second largest man-made lake in the United States by total water capacity (after only Lake Mead), extending 186 mi upstream through the canyons of Arizona and Utah. The lake covers 161390 acre at its full pool elevation of 3700 ft. The active, or useful capacity is 20.876 e6acre feet. The minimum water level required for power generation is 3490 ft, corresponding to storage of 4.0 e6acre feet, and the "dead pool", the lowest point at which water can be released through the dam, is 3370 ft with storage of 1.9 e6acre feet. When Glen Canyon Dam was first built, the reservoir capacity 
Title: Lake Powell
Content:  Lake Powell is an artificial reservoir on the Colorado River in Utah and Arizona, United States. It is a major vacation spot visited by approximately two million people every year. It is the second largest artificial reservoir by maximum water capacity in the United States behind Lake Mead, storing 24,322,000 acre.ft of water when full. However, Lake Mead has fallen below Lake Powell in size several times during the 21st century in terms of volume of water, depth and surface area. Lake Powell was created by the flooding of Glen Canyon by the Glen Canyon Dam, which also led to the 1972 creation of Glen Canyon National Recreation Area, a popular summer destination of public land managed 
Title: Lake Tahoe
Content:  Lake Tahoe (, meaning "the lake") is a large freshwater lake in the Sierra Nevada of the United States. Lying at 6225 ft, it straddles the state line between California and Nevada, west of Carson City. Lake Tahoe is the largest alpine lake in North America, and at 122160280 acre.ft it trails only the five Great Lakes as the largest by volume in the United States. Its depth is 1645 ft, making it the second deepest in the United States after Crater Lake in Oregon (1949 ft). The lake was formed about two million years ago as part of the Lake Tahoe Basin, and its modern extent was shaped during the ice ages. It 
Title: Milford Lake
Content:  Milford Lake, also known as Milford Reservoir, is the largest man-made lake in Kansas with 15700 acre of water. Over 33000 acre of land resources are managed for quality recreational experiences as well as for protection of the project’s natural and cultural resources. Approximately 70% of the land resources are available for public hunting.
Title: Lake Winnipesaukee
Content:  Lake Winnipesaukee is the largest lake in the U.S. state of New Hampshire, located in the Lakes Region at the foothills of the White Mountains. It is approximately 21 mi long (northwest-southeast) and from 1 to 9 mi wide (northeast-southwest), covering 69 sqmi&mdash;71 sqmi when Paugus Bay is included &mdash;with a maximum depth of 180 ft. The center area of the lake is called The Broads. The lake contains at least 264 islands, half of which are less than a quarter-acre in size, and is indented by several peninsulas, yielding a total shoreline of approximately 288 mi. The driving distance around the lake is 63 mi. It is 504 ft above sea level. Winnipesaukee is the third-largest lake in New England after Lake Champlain and Moosehead Lake. Outflow is regulated by the Lakeport Dam in Lakeport, New Hampshire, on the Winnipesaukee River.
Title: Shasta Dam
Content:  cuft/s. The dam forms a reservoir called Shasta Lake, which is the largest man-made lake and third largest body of water in California with its capacity of 4552000 acre.ft and surface area of 29740 acre at maximum pool. The lake extends for 15.3 mi up the Sacramento River and branches for more than 21 mi up the Pit River, which is actually the largest river flowing into the lake. Shasta Lake also has arms of the McCloud River, Squaw Creek, Salt Creek, and scores of other smaller streams that feed it. Shasta Dam controls runoff from a drainage basin of 6665 sqmi, or about a quarter of the 27580 sqmi Sacramento River watershed.
