Streamflow depletion estimates have been made and subsequently revised on a
number of occasions since the Pick-Sloan plan Has first authorized. T\;o of
the most comprehensive estimates are those presented in the 1951 ~lBI^C report
on Adequacy of Flo\;s and in the 1969 FramCliork Study. These two depletion
estir.\ates arc shOlm on Exhibit 3 for comparison "i th current estimates \;hich
Here prepared in connection \;ith the Northern Great Plains Resource Program.
In general the current estim~tes are in the range of magnitude of earlier
estimates.

Although actual depletions have been some\;hat slO\ier than previous projections,
as demonstrated for the 1949 to 1970 period on E~\bit 3. Curves A, B, and C
on this exhibit represent future depletions under the fo1101dng possible
conditions of upstream \;ater use:

A. Depletions \;ith full USBR irrigation development and 3.0 million
acre-feet for coal development (reasonable maximwn depletions).

B. Depletions with partial USBR irrigation development 1.4 million
acre-feet for coal development (most likely depletions).

C. Depletions liith partial USBR irrigation development and 0.7 million
acre-feet for coal development (reasonable minimum depletions).

The depletion estimates for coal development recognize the interest which has
been expressed by numerous ellergy companies. Since 1967, options on storage
water,have been t~ken by ~OTe than a dozen companies totalin~ 712,000 ac:e-feet
from Boysen Reservoir, Lake Bighorn (Ye llolitail) and Tong~e. R7 vel' Res~rVolT..
The follo'.;ing Table shows current interest in water acqu1s1t10n for 1ndustr1al
uses. Quantities are in acre-feet per year.
