While the temporary diversion is being constructed, same
water will be allowed to flaw past the diversion in the
existing channel at the same time water is directed into the
Phase I area. This will allow the Phase I channel to become
saturated as water flows northward to where it will re-join the
existing channel. The quantity of water in the main channel
will be temporarily decreased while this flow is
re-established. This will be done in early spring or late fall
when flaws are slightly higher than in winter, but not during
irrigation season when there is a greater demand by downstream
users.
To assure that the quality of the groundwater is not
adversely affected by the proposed operations, water sampling
of the Webb well has been started so that baseline data is
available. The Webb well will be routinely Sampled. If the
water table rises to where there is water in any of the three
monitor wells, samples will also be taken at these locations.
5. Please refer to the enclosed Buckhorn Geotech analysis
dated February 10, 1992.
6. As described in Item 4 above, the proposed diversions
will be scheduled at times when the river volume is slightly
higher than normal, but at times when demands of irrigation d^
not exist. The month of April has mean flows twice those of
the winter months, but is prior to the high flows of May to
June and is also before the irrigation season. The months of
September and October also have flows higher than in the winter
and are also at a time when the irrigation demands are
decreasing or have stopped.

9. The east boundary of the permit area is in the center
of the historic high-water channel as indicated on Exhibit E -
Map. Since the boundary of the Phase II excavation has been
moved so as not to disturb the mature cottonwood trees along a
portion of the boundary, riprap will be placed along the
excavation near the trees as indicated on Exhibit E -
keclamation Plan Map. A rail/wire structure will be placed
along the east boundary, 4rom the southern permit boundary to
this riprap for additional erosion control.
10. Please refer to E>:hibit E - keclamation Plan Map.
11. The present river channel on the north end of the
• property is in a direct line with the Phase I excavation and
the flow will be directed to this channel as the river is
diverted for F'hase II. As discussed at our on-site meeting
January 16, 1992, it would be advantageous to keep the flow of
