At that time, <br />Denver's Near-Term strategy included several system refinements, new supply projects, <br />nonpotable reuse and conservation programs, (The primary reason for the slight increase <br />in estimated unused divertible supplies in spite of a higher demand level for Denver is the <br />inclusion of the years 1975 -1991 in Denver's model studies. These years contained <br />exceptionally large runoff seasons,) <br /> <br />This second estimate was used in the Southern Regional Cooperative Action Study <br />(SRCAS), and was done as a follow-on study to the overall MWSI. Denver's unused <br />divertible surface supplies from the South Platte and Blue River would have several <br />major advantages in a conjunctive use arrangement They represent a high quality supply <br />that could be diverted at Strontia Springs, close to the major areas of municipal use of <br />Denver Basin groundwater. As discussed in the following sections, most of this supply <br />could be effectively regulated using existing surface reservoirs under a conjunctive use <br />arrangement However, it should be noted that the availability of this supply would be <br />subject to Denver's future plans, water rights constraints, envirorunental/permitting <br />considerations and West Slope concerns, <br /> <br />43 <br /> <br />Prepared for the Colorado Water Conservation Board, Colorado Department of Natural Resources by <br />Hydrosphere Resource Consultants, 1002 Walnut Street, Suite 200, Boulder, CO 80302 <br />
