Dear tQr. Haines:
In accordance with our ac •ement we submit this report of
the results of our investigation into the water plans
related to tt>e Kilgroe-Atchison Construction and Paving
Company's gravel mine near Henderson.
AREA WATER PESOURCES
The mining site as shown in Figure 1 is located partly in
ara adjacent to the floodplain of the South Platte River
in Section 26, T.I.S., R.67.W. in Adams County, Colorado.
In this area the South Platte River is a sand bedded channel
meandering within an alluvial floodplain approximately 2
miles wide. The alluvium contains s1.311oca gr.,und water that
is hydraulically connected to the surface stream system.
Flow in the South Platte River ~s derived from snow melt ire
the high mountains augmented by West 51opc• Ovate- imported
for municipal use in the Denver Metropolitan area. Prior
to development of irrigated farming in the South Platte
River Basin, the lower reaches of the river were dry for
vazious periods of time. The appropriation of water for
irrigation, a portion of which returns to the stream system,
and the importation of water from Western Colorado leave
resulted in a more stable base flow during periods of low
flow. In recent years, especially since low cost electric
power has become widely available, there has been a sharp
rise in the number of pumped'well.s uses for irrigation at~d
other purposes. These wells tend to lower the shallow
ground water table during the irrigation season and provide
ground water storage which can be recharged during the spring
runoff period.
Ground water in the area is available from the alluvium at
shallow depths and is hydraulically connected to the surface
stream system and as such is considered tributary and sub-
ject to administration unc. ~ the appropriation doctrine.
Deep wells in the area could withdraw ground water from a
variety of formations. Ground water in the deeper formations
is not hydraulically connected to the surface stream system
and therefore is considered non-tributary. Shallow gr end
water in the area is continuously flowing slowly downstream
through the sands and gravels of the floodplain deposits.
