In sharp contrast, the period between 14,300 and 11,100 years ago, which includes the Younger Dryas interval, was an interval of reduced sea level rise at about 6.0–9.9 mm/yr. Meltwater pulse 1C was centered at 8,000 years ago and produced a rise of 6.5 m in less than 140 years, such that sea levels 5000 years ago were around 3m lower than ...
The low water was a continuation of the dropping lake levels from the previous year, 1925, which set low-water records for October through December. During the nine-month period of October 1925 to June 1926, water levels ranged from 1.58 feet (0.48 m) to 0.33 feet (0.10 m) below Chart Datum. [ 27 ]
The water level in Lake Ontario has remained relatively constant in the same time period, hovering around the historical average level. [35] Water levels of Lakes Michigan and Huron in the United States, 1918 to 2019. Although "true tides—changes in water level caused by the gravitational forces of the sun and moon—do occur in a semi ...
In time, this resulted in major land subsidence by the 1970s with local areas having 0.30 to 8.5 m (1 to 28 ft) of subsidence. With the creation and use of the California Aqueduct along these regions, surface water being transported put a halt on significant compaction and a recovery in ground water levels now with less ground water pumping.

Not all waters have had these facts determined, and so are of uncertain status. All water subject to tides are included. Note that the "Navigable Waters of the United States" listed in 33 CFR 329 are different than those listed as "Waters of the United States" in 33 CFR 328, which is the Clean Water Rule. However, all Navigable Waters, plus ...
This is a list of largest reservoirs in the United States, including all artificial lakes with a capacity greater than or equal to 1,000,000 acre-feet (1.2 km 3). Figures given are for maximum storage capacity (flood pool) of reservoirs, not regular storage volume (conservation pool).

The nearly 8100 major dams in the United States in 2006. The National Inventory of Dams defines a major dam as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3).
