This map shows the generalized service areas within the City of Pocatello. The heavy black line marks the approximate boundary of the aquifer. The map was created for summertime conditions, when almost all municipal wells are pumping. In winter, when demand drops substantially, the pattern changes slightly according to which wells are turned off.
The map is intended to give a general indication of which wells you would expect to obtain your water from. Because of the proximity of a number of wells, they have been grouped into service areas. If you live in an area of overlap between service areas, you could expect to receive a mixture of water from wells in adjacent service areas. The most important wells in each service area are indicated on the map.
