My Aquifer > Groundwater Basics > How much water does the aquifer supply?

 

Ground water use by the cities has grown in proportion to their populations. Figure 11 shows a graph of Pocatello's annual water use and population since 1950. Note that in the past, Pocatello obtained water from both ground water and Mink Creek surface water supplies; Surface water supplies were phased out completely in 1993 due to the high cost of treating surface water to comply with federal regulations.
