Cool Maps consists of an interactive map,
picture and text tour of the Portneuf watershed, the Lower Portneuf River Valley aquifer,
and the relationship of both to the quality of municipal drinking water in Pocatello and Chubbuck.
With Cool Maps you will explore the LPRV
aquifer, the major subdivisions of the aquifer, the locations of municipal water service
areas, wells, storage basins and more. Cool Maps will let you pinpoint your geographic
location, find the municipal wells that supply the water flowing from your
taps and then zoom in on detailed water quality data and information.
At each stop on the Cool Maps Tour examine
the maps, read the explanatory text, explore any companion links, then follow the
instructions highlighted in bold at the bottom of each segment. Begin by reviewing the
Portneuf Watershed & LPRV Aquifer information at right, then locate the Portneuf
Watershed on the map and CLICK to start your Cool Maps Tour!
Not on municipal water? You can
get a good idea of the general quality of your private well water by locating the city
well nearest to you using Cool Maps, then accessing the associated well data and
PORTNEUF WATERSHED & LPRV AQUIFER
|Most people in the area know
that our drinking water is pumped from an underground reservoir of fresh water beneath our
feet known as the Lower Portneuf River Valley (LPRV) aquifer. What
you may not realize however, is that most of the well water distributed
to you by the cities' supply systems originally came from surface water drainage
flowing through our watershed.
IWI COLOR KEY
FOR THIS MAP
A watershed is the land
area from which
water drains into a given stream, river,
reservoir or other water body.
The quality of water in our
watershed correlates directly to the quality of the well water we drink.
The United States
Environmental Protection Agency has assigned an Index of Watershed Indicators (IWI) to
each watershed in the United States, including those in Idaho. The IWI categorizes
watersheds based on their overall aquatic health. A wide variety of indicators are used to
determine an IWI score. These indicators are environmental factors that influence the
health of the watershed and hence the quality of our drinking water.
Find the Portneuf
watershed on the map above,
then CLICK to zoom in on our IWI score and take
an interactive look at the watershed, the LPRV
aquifer and our municipal drinking water supplies!
