2.06.8
• Both of these areas show evidence of historic or current
agricultural use. Since the presence of an alluvial valley floor
is not at issue then, in accordance with 2.06.8(3)Ibl, extensive
field investigations are not required.
Numerous small alluvial deposits exist along Naturita Creek
from the mouth of Broad Canyon to the San Miguel River. Along
this meandering stretch, Naturita Creek curls from one side of
the canyon to the other and forms these small alluvial deposits.
All of these deposits are covered with brush and trees. According
to Rule 2.06.8(3)(c)i, these deposits probably have the inherent
productive potential to support agricultural activities. Howev-
er, they are not currently being farmed and may not meet a mini-
mum size criteria.
There is an area adjacent to Area 1 identified above which
also may have the inherent productive potential to support agri-
cultural activities. This area currently supports a stand of
large cottonwood trees.
All of these locations are shown on the Alluvial Valley
Floor Location Map, Drawing No. 125.
Three alluvial wells were installed in the locations shown
on Map 110. The purpose of the wells was to provide information
• on the relationship between the surface water system and the
alluvial water system. All three wells were dry when they were
installed in 1989. Monitoring of the three wells during 1989,
1990 and so far in 1991 continue to show that no alluvial water
system exists in the permit or surrounding area.
The proposed mining operation is over one mile from the
identified alluvial valley floors; therefore, it will not inter-
rupt, discontinue, or preclude farming on the alluvial valley
floors.
The maximum depth of mining during the first five year
permit term is about forty feet. Aa discussed in Section 2.04.7,
the depth to the potentiometric surface lies between 100 and 120
feet throughout the permit area. The mine is not expected to
encounter any ground water. The only discharge from the mine
permit area will be from surface run-off which has first passed
through an approved sedimentation pond. The physical location of
the mining operation relative to the identified alluvial valley
floors, about 400 feet higher in elevation and about one mile to
the south, further indicates that the mining operation will not
materially damage the quantity or quality of ground water systems
that supply the identified alluvial valley floors.
