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 flood created a channel in the moraines and bedrock lower water level in the Erie basin. [2] The Niagara River Outlet, was over 50 metres (160 ft) lower than the present level of Lake Erie [3] creating a non-glacial lake, called Early Lake Erie. At this stage water elevation was 120 metres (390 ft) above sea level.
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 ...
Image showing sea level change during the end of the last glacial period. Meltwater pulse 1A is indicated. Meltwater pulse 1A (MWP1a) is the name used by Quaternary geologists, paleoclimatologists, and oceanographers for a period of rapid post-glacial sea level rise, between 14,700 and 13,500 years ago, during which the global sea level rose between 16 meters (52 ft) and 25 meters (82 ft) in ...
The reference water levels are used on inland waterways to define a range of water levels allowing the full use of the waterway for navigation. [1] Ship passage can be limited by the water levels that are too low, when the fairway might become too shallow for large ("target", "design") ships, or too high, when it might become impossible for the target ships to pass under the bridges.

A water resource region is the first level of classification used by the United States Geological Survey to divide and sub-divide the United States into successively smaller hydrologic units as part of the U.S. hydrologic unit system. This first level of classification divides the United States into 21 major geographic areas, or regions.
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 to 0.33 feet (0.48 to 0.10 m) below Chart Datum. [ 27 ]
