How Many People Can an Aquifer Support?
ES1406  Estimated Water Use

In 1884, when wells first began discharging water from the Arapahoe aquifer, the water was used primarily for irrigation. The population was small, livestock was not much of a factor, and large industries didn't exist.

As the population changed, however, so did water use patterns. Agricultural and industrial users still get much of their water from the aquifer, but more of the water for public use now comes from surface water, which is stored in reservoirs.
