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]

In confined aquifers , the cone of depression is a reduction in the pressure head surrounding the pumped well. When a well is pumped, the water level in the well is lowered. By lowering this water level, a gradient occurs between the water in the surrounding aquifer and the water in the well. Because water flows from high to low water levels or ...
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 ).
The spring water travels about 1,000 feet (300 m), where it adds itself to the Current River. The water is about 58 °F (14 °C), and the spring is surrounded by a well-maintained park and a steep valley hillside covered in hardwood forest. Most of the known drainage basin encompasses northern areas of the Eleven Point River watershed.
The Current River begins in Montauk State Park located in the southwestern corner of Dent County in southeastern Missouri. The confluence of Pigeon Creek and Montauk Spring form the headwaters of the river. Montauk Spring makes up most of the consistent flow of the headwaters, providing ideal conditions for trout fishing.
Shoal Creek is an 81.5-mile-long (131.2 km) [3] stream tributary of the Spring River in southwest Missouri and southeast Kansas.It begins in Barry County, Missouri southwest of Exeter and flows west through Newton county in Missouri before emptying into the Spring River near Riverton in Cherokee County, Kansas.
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 ).
