For the purpose of this study, with the exception of the Black
Mesa, the hydrologic data given in USBR's Definite Plan Report [2]
were reviewed and used. The values of runoff and the ditch diver-
sions, thus obtained and used in the operation s-tudy, are given as
follows:

I

1. Crystal Creek. The drainage area contributing runoff is 42.2

square miles and has a mean elevation of 9,570. The annual

average runoff for each month during the 25-year period of study

,
is 25,000 acre feet and is outlined in Table 1.

2. Iron Creek. All runoff of the Iron Creek flows into the

Gould Reservoir. The drainage area is 22 square miles and the

average runoff, as given in Table 2, is 1,000 acre feet. The

drainage basin of the Crystal Creek is at a higher elevation than

that of the Iron Creek and, therefore, catches more snowfall.

Inasmuch as the primary source of runoff in 'the project area is

snowfall, the runoff in the Crystal Creek, per unit area, is more

than the corresponding runoff of the Iron Creek.

3. Black Mesa. The runoff from the slopes of Black Mesa takes

place in several creeks and gulches. The drainage areas behind

those streams are as follows:

Cottonwood Creek 5.86 mi2
Buckhorn Gulch 1.69 mi2
Long Gulch 4.51 mi2
Mesa Creek 9.15 mi2
Total 21.21 mi2
