Dear Dick:
Submitted with this correspondence is the 1980 aerial photograph from which
Blatchley Associates, Inc. based their original report (Plan of Augmentation) of
October 1990. While the balance of Pre-law acres of water has remained in
dispute since that time, it is unclear whether or not the balance of the report is
acceptable relative to determining the total acre feet of water to be augmented
for (under a Temporary Plan of Supplemental Augmentation) and water
available to meet that need (specifically, Table 3 and Table 7 of that report).
Atour meeting on 20 June 1996, you and Chris Varra agreed that the 54.1 acres of
pre-law water determined in the Blatchley report would be acceptable to the
State Engineer, upon verification by your office. A 1979 aerial was the most
current information available to confirm Blatchley's measurements at the time.
Based upon the area measurements by your geotechnical section, your office
determined only 50.1 surface acres of pre-law water in the 1979 aerial.
Since that time, we have researched various Front Range air photo services and
discovered the April 1980 aerial upon which the Blatchley measurements were
based. The 1980 aerial reveals additional water bodies evident over the area of
interest not yet validated by your Office. The measurement of these areas is
included with this submittal.
