make replacements to the river. A five-year lease dated August 1, 2017 was obtained to
provide replacement supplies during this SWSP approval period from the Upper Arkansas
Water Conservancy District ("UAWCD"). The minimum and maximum amounts of leased water
for each year of the agreement are shown in the table, below:

Valco owned 2 shares in the Rocky Ford Ditch, which have been transferred to Deep Cut.
However, these shares may result in consumptive use credits in excess of what Deep Cut
required for this season. Valco may, with approval from Deep Cut and the Division Engineer,
use a portion of those shares as part of its SWSP replacement requirement.
