<br />The District holds several water rights that are presently decreed for municipal purposes, The
<br />two main water rights are 6,00 cfs of Priority No, 2, originally decreed to the Simonton Ditch,
<br />and 3,00 cfs of Priority No, 3, originally decreed to the Hodgson Ditch, These water rights are
<br />sufficient to satisfy the District's existing demands: however other factors such as low flows in
<br />Bear Creek due toa drought year may cause the water system to not be able to fully satisfy the
<br />demands associated with the expected future growth, In particular, the drought year water flow
<br />may not be adequate to satisfy the total system demand for (1) potable, water on peak days, (2)
<br />golf course irrigation, (3) park and open space irrigation, and (4) replaCing the evaporation at
<br />Evergreen Lake, When a drought year water shortage happens, Evergreen will need to draw
<br />water from storage in Evergreen Lake, and will want to replenish that storage as soon as possible
<br />afterward,
<br />
<br />To assist in providing water for these additional purposes, Evergreen has acquired additional
<br />water rights in ],B, Grant Reservoirs A and B, Soda Lakes Reservoirs, and the Pioneer Union
<br />Ditch, filed in the water right application in Case No, 94 CW 150 in the Division 1 Water Court,
<br />In this application, the District sought to (1) obtain conditional water storage rights for the First
<br />Enlargement of Hiwan Reservoir No.8 and for Hiwan Reservoir Nos, 9 andIO; (2) change its
<br />interests in Soda Lakes Reservoirs, ],B, Grant Reservoirs A and B, and Pioneer Union Ditch to
<br />allow them to be used and stored for municipal purposes; (3) obtain rights of substitution and
<br />exchange on Bear Creek; and (4) obtain approval for a plan for augmentation,
<br />
<br />The District's interests in the ],B, Grant Reservoirs A and B and Soda Lakes Reservoirs were
<br />used historically to provide part of the water supply for irrigating the Grant Ranch, From
<br />1948-73; these water storage rights provided an average of 285,7 acre-feet annually at the
<br />Harriman diversion facilities on Bear Creek. Analyses described herein indicated that
<br />approximately 55.0 percent of this water was consumed through evaporation and
<br />evapotranspiration, and 45,0 percent returned to Bear Creek and Coon Creek. Of this total return
<br />flow, approximately 73,0 percent occurred during the months of April through October, and 27,0
<br />percent occurred during the months of November through March, The yield under the District's
<br />interests in these water storage rights would be reduced by provisions in the decree in Case No,
<br />86 CW 252 to approximately 210.2 acre-feet annually under these same hydrologic conditions,
<br />The return flow obligation on this average yield will amount to 94,6 acre-feet annually, After a
<br />drought year draw down of Evergreen Lake, the water in storage at Soda Lakes Reservoirs could
<br />be used to refill Evergreen Lake's storage by exchange,
<br />
<br />The District's Pioneer Union Ditch water rights were used historically on the Desserich Farm.
<br />The yield of these rights from 1949-67 averaged 164.4 acre-feet annually at the Pioneer Union
<br />head gate and 139,7 acre-feet annually at the Desserich Farm, The stream depletion averaged
<br />63,8 acre- feet annually, which was the result of 77 ,5 acre-feet of stream depletion during April
<br />through October and 13,7 acre-feet of net return flow during November through March,
<br />
<br />Tenus and conditions on the final Water Court approval of 94C-W-150 in April 17, 1998 have
<br />been agreed to, allowing the District to use these water rights for these various municipal
<br />purposes while protecting other water users in Bear Creek and South Platte River basin from
<br />injury,
