52.04 APPLICATION FOR PERMIT FOR SIIRFACE OR UNDERGROUND MINING ACTIVITIES --
MINIMOM REQUIREMENTS FOR INFORMATION ON ENVIRONMENTAL RESOURCES.

2,04.7 Hydrology Description.
(2) Surface Water Information.
(a) and (b) (Cont'd.)
Roatcap Creeks to the .North Fork is also usually dry
following spring run-off, as most flows are diverted
upstream for irrigation. Livestock and wildlife util-
ize water from these streams and from many scattered
stockponds. Riparian vegetation exists along the im-
mediate streambanks of the creeks, confined by the
steep topography and narrow alluvial/colluvial deposiCs
within the streambed. No extensive riparian or other
unique habitats are known to exist along the streams.
Stockwater Ponds Within Permit Area:
A considerable number of ponds exist within the permit
area. Most of these ponds are man-made and serve for
stock watering. Only a few of the ponds are used for
other purposes such as irrigation or domestic. Sizes
of ponds are as small as one hundred square ft. to as
• big as one acre. Ponds within the permit area are typ-
ically fed by run-off during the spring season; howev-
er, many ponds are related to colluvial springs and
seeps. During the field reconnaissance, the storage
capacity and the source of water for each of the ponds
was evaluated. The data pertinent to monitoring of
ponds and springs are presented on Tables 2 and 3 in
Voliane 4. Although the ponds are a significant hydro-
logic feature of the permit area and their existence is
important to the local water users, total contribution
of these ponds to the local water budget is not signif-
icant. No ponds are located in the area of the Orchard
Valley West Mine. The significance of ponds for land
use considerations can be found in Section 2.05.6,
Probable Hydrologic Consequences of the Proposed Mine.
Surface Water on Mine Facilities Area:
Surface water run-off associated with the applicant's
operations is controlled by the Orchard Valley Mine
Drainage Plan. All water is routed through a series of
sedimentation dams with any surface water discharged
from the last pond flowing into Steven's Gulch at the
