Further downstream, the flow of water may be reversed and the stream may recharge an associated alluvial aquifer in a “losing” reach. In many cases, gaining and losing reaches alternate along the same streambed depending on the relative elevations of groundwater and streamflow and local geologic conditions.The Missouri River alluvium is thickest and most used in Kansas near its junction with the Kansas River valley at Kansas City. Alluvial aquifers in other river valleys in Kansas such as the Smoky Hill, Solomon, Saline, Neosho, Marais des Cygnes, and Verdigris also are locally important sources of ground water.

For example, an alluvial aquifer consists of loose sand, gravel, silt, and clay deposited in a stream valley or floodplain, and it is hydrologically connected to the stream flowing on its surface (figs. 1 and 2).

Where present, the alluvial aquifers in the upper basin are valley-fill deposits composed of glacial till, outwash deposits, lacustrine deposits and alluvium. In the lower basin, the alluvial deposits thicken and form a continuous aquifer network, serving as a major groundwater resource.The uppermost aquifer consists of the alluvium (or the "alluvial aquifer"). Since there is no layer between the surface and the alluvium, the alluvial aquifer is not bounded above. Based on the 100-fold difference in hydraulic conductivity, the alluvial aquifer is bounded below by the limestone unit.Irrigation wells completed in the aquifer generally yield between 200 and 2,500 gallons per minute and average about 1,000 gallons per minute.

In 2010, a combined total of about 27.1 million gallons per day (Mgal/d) of groundwater were pumped from the Red River alluvial

Ground water infiltrates the alluvial aquifer from the tuffs via springs and subsurface flow. The close proximity of the water table in the alluvium to the ground surface promotes evapotranspiration, and evapotranspiration causes a decrease in the volume of ground water and an increase in chemical concentration. Colinear increases in
