available for storage. The scenario does, however, depict in an
average year what the total intra-basin water amounts attributable
to snowmelt are. This water is, however, not necessarily available
water for storage or irrigation purposes.
The amount of truely available water attributable to
snowmelt would be very difficult to quantify because it would depend
on ground infiltration rates, evapotranspiration rates, the rate at
which the snow melted and the length of time taken for the ground to
become saturated enough to promote direct runoff. Therefore, the
statement that was made by the authority referring to the calculated
yield being much greater than the actual volume is correct. This
leads us to the belief that water availability within the Bolton Draw
watershed itself does not occur in reliable or great enough quantities
to be depended upon for use in irrigation. This is undoubtedly the
reason why past irrigation attempts in Bolton Draw used water from
the trans-basin Spear Ditch, a more reliable source.
The applicable water yield from the North Fork of Bolton
Draw has already been quantified in terms of mining impact to the
surface flow potentially available to the downstream reaches of Main
Bolton Draw. The authority is directed to Section 2.05.6(3)(b)(iv)
Page 92 which states that "...2.70 of the potential surface water
flow to the Bolton Draw drainage will be reduced by sediment pond
detention from the Canadian Strip Mine".
3) Wyoming Fuel Company has never doubted the existence of
potentially subirrigated regions within the downstream reaches of
Main Bolton Draw. We will accept the configuration of this potentially
subirrigated area as indicated by the referenced Marr Strip Mining
and Reclamation Plan Technical and Environmental Analysis and the
Technical Analysis of the Canadian Strip Mine. To spend time
reevaluating this area is a needless duplication of effort.
Wyoming Fuel Company has made a concerted effort to
demonstrate that continuation of the Canadian Strip Mine around
the nose of the anticline will have no appreciable effects on the
hydrologic regime in the North Fork of Bolton Draw or in the down-
stream reaches of Main Bolton Draw. This detailed analysis is
presented in Section 2.05.6(3)(b)(iv) Pages 92-99 under Prediction
of Probable Hydrologic Consequences.

The soil testing program will include analysis of those para-
meters listed in Attachment 3 of Addendum I of July 28, 1981 sub-
mitted by Wyoming Fuel Company. Approximately three (3) soil
samples will be taken on an annual basis prior to fall seeding.
Three samples is an approximation. As the size of the reclaimed
