Colorado River basin to the Arkansas River basin via the Homestake Tunnel (map
number 22). After flowing down the Arkansas River for about 20 miles, the
water then is pumped into the South Platte River basin via the Aurora-
Homestake Pipeline (map number 26). This water eventually reaches Aurora
water-treatment plants via the South Platte drainage system. Through
mechanisms such as this, an average of about 16 percent of the water withdrawn
in the South Platte subregion and about 6 percent of the water withdrawn in
the Upper Arkansas subregion originates in other subregions primarily located
on the other side of the Continental Divide.

Water Source

Source information consists of source type and water-supply method
(fig. 3). There are two primary source types for water--ground water and
surface water. For the irrigation water-use and power water-use categories,
an additional source type of water was reclaimed sewage. The State Engineer's
Office maintains information about surface-water and ground-water sources in
two state-wide data bases--a well-permit file and a surface-water diversion
