Alterna ti ve I

The first alternative considers water supplies available in the Tongue
Creek basin only. Water would be diverted through the Surface Creek
feeder canal to the Cactus Park reservoir. Storage would take place in
the reservoir when all other estimated demands on the system are
satisfied. Releases would be made from the reservoir to the lower
basin through the Cedaredge canal. The flows available from the
Tongue Creek basin are limited by the capacity of the Surface Creek
feeder canal and are reduced to account for an expected conveyance
loss of five percent.

This alternative would include the following plan components:

The Cactus Park reservoir with a storage capacity of 21,200 acre-
feet (for 90 percent firmness) and an inactive storage of 5,000
acre-feet to take into account recreation needs and contingen-
cies.

The Surface Creek feeder canal used to convey Tongue Creek
basin surplus water to Cactus Park reservoir over a distance of
7.7 miles.

The Cedaredge canal used to convey water from Cactus Park
reservoir to irrigators in the Lower Tongue Creek basin over a
distance of 10.2 miles.

Alternative 2

In the second alternative, it is proposed to add excess water from the
Leroux Creek basin to the Tongue Creek basin water supplies through
the Leroux Creek feeder canal. Water from both the Tongue Creek and
Leroux Creek would be stored in the Cactus Park reservoir.
