In a confined aquifer, groundwater is stored between two impermeable layers and is often under pressure.
The water in a confined aquifer is trapped and often under pressure.
Artesian wells, which produce water from confined aquifers, often do not require pumping because of this pressure.

Term
| is groundwater renewable or non-renewable? |
|
Definition
Most groundwater is considered a nonrenewable resource because it has taken hundreds or even thousands of years to accumulate, and usually only a small portion of it is replaced each year by percolation of precipitation.
The recharge of confined aquifers is particularly slow. |

The removal of ground-water more rapidly than it can be recharged by precipitation or melting snow.
In addition, aquifer depletion from porous sediments causes subsidence, or sinking, of the land above it. |

- It stipulates an annual allotment of 7.5 million acre-feet of water to the lower Colorado (California, Nevada, Arizona, and New Mexico) and the remainder to the upper Colorado (Colorado, Utah, and Wyoming).
- However, the Colorado River Compact overestimated the average annual flow of the Colorado River, which at the time was thought to be 15 million acre-feet.
- Consequently, the Colorado River water is often completely consumed before it can reach the Pacific Ocean
- To compound the problem, as more and more water is used, the lower Colorado becomes increasingly salty as it flows toward Mexico; in places, the Colorado River is saltier than the ocean.
- In 2003 California agreed to withdraw no more water from the Colorado River than the Colorado River Compact permits.

- Dams ensure a year-round supply of water in areas with seasonal precipitation or snowmelt.
- Dams confine water in reservoirs, from which the flow is regulated
- Dams have other benefits, particularly the generation of electricity (recall the discussion of dams and hydroelectric power.
