Following is a list of dams and reservoirs in Missouri. All major dams are linked below. The National Inventory of Dams defines any "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 ).
The pump-turbine units were uprated in July 1972 from their initial rating of 175 MW each to 204 MW each, increasing the plant's overall rating from 350 MW to 408 MW. [3] [16] From 1998–1999, the turbine runners for both units were upgraded, resulting in improved flow rates and another power uprate to 225 MW per unit (450 MW total). [17] [16]
where s is the drawdown (change in hydraulic head at a point since the beginning of the test in units of distance), u is a dimensionless parameter, Q is the discharge (pumping) rate of the well (volume per unit time), T and S are the transmissivity and storativity of the aquifer around the well (distance squared per unit time and dimensionless ...
In hydrology, a well test is conducted to evaluate the amount of water that can be pumped from a particular water well.More specifically, a well test will allow prediction of the maximum rate at which water can be pumped from a well, and the distance that the water level in the well will fall for a given pumping rate and duration of pumping.
Aquifer test (or a pumping test) is a field experiment in which a well is pumped at a controlled rate and the aquifer's response (drawdown) is measured in one or more observation wells. [5] Cone of depression is a conically-shaped depression that is produced in a water table as a result of pumping water from a well at a given rate. [4]
The average population of Missouri's counties is 53,880; St. Louis County is the most populous (987,059), and Worth County is the least (1,907). The average land area is 599 sq mi (1,550 km 2 ). The largest county is Texas County (1,179 sq mi, 3,054 km 2 ) and the smallest is St. Louis city (61.9 sq mi, 160 km 2 ).
A cone of depression is a circular area surrounding a well where groundwater levels are reduced from pumping. [1] [2] In an unconfined aquifer (water table), this is an actual depression of the water levels. In confined aquifers , the cone of depression is a reduction in the pressure head surrounding the pumped well.
Clearwater Lake is a reservoir on the Black River, six miles (9.7 km) from Piedmont, Missouri. The U.S. Army Corps of Engineers uses Clearwater for flood control in the White and lower Mississippi River Basins. Clearwater Lake was so named on account of its clear, spring-fed water. [2]
