2007 is 652,897 (750,831 minus the quantity 65,289 times 1.5 years). For the second year of the Program of 2008,
<br />the population increase since July 1, 1997 used in the analysis for July 1, 2008 is 718,186 (750,831 minus the
<br />quantity 65,289 times 0.5 years). For the first year 2009 of the next 5 -year reporting period, for July 1, 2009 the
<br />population increase is 777,159 (750,831 plus the quantity 52,657 times 0.5 years). For the last year 2013 of the next
<br />5 -year reporting period, for July 1, 2013 the population increase since July 1, 1997 is 987,787 (750, 831 plus the
<br />quantity 52,657 times 4.5 years). The yearly difference of 52,657 will be added each year for the years of the 5 -year
<br />reporting period (2009 through 2013) unless modified by another SDO update.
<br />CPFD Questionnaire
<br />In the effort to check and adjust the main assumptions of percent mix of water sources and gross per capita use, a
<br />questionnaire was developed and circulated to the municipal members of the South Platte Water Related Activities
<br />Program, Inc. ( SPWRAP). Email, phone calls and meetings were used for follow -ups on the questionnaires to
<br />ensure that consistent data was provided by the members. SPWRAP is the non - profit corporation of mainly South
<br />Platte municipal entities (also agricultural and industrial members) working with the State of Colorado to meet
<br />Colorado's water obligations for the PRRIP. SPWRAP has an annual assessment for all their members. For 2009,
<br />the annual municipal assessment was S 1.20 per tap. These funds are used in water project development, operations
<br />and acquisition of water for the CPFD mitigation and Colorado's Initial Water Project (Tamarack 1).
<br />Questionnaires were sent to 30 municipal entities. With respect to the regions of the CPFD analysis, 14 entities
<br />were in the Northern region, 9 entities were in the Central region and 7 entities were in the Southern region. To
<br />determine the level of representation of the SPWRAP members with the overall municipal usage, the questionnaire
<br />asked the amount of population served by the entities water supply for baseline year 1997 and current year 2008.
<br />The total population difference between baseline 1997 and current 2008 for all three regions from the questionnaires
<br />is 578,208, which is 77% of the total population difference of 750,831 listed in the attached SDO report. This
<br />overall 77% level of reporting with the questionnaires and the reporting by region is considered to be a good
<br />representation. The population difference between 1997 and 2008 determined from the questionnaires for the
<br />Northern region is 129,706, which is 60% of the population difference for the Northern region of 217,398 listed on
<br />the table in the attached SDO report. The population difference determined from the questionnaires for the Central
<br />region is 348,803, which is 98% of the population difference for the Central region of 356,007 listed on the table in
<br />the attached SDO report. The population difference determined from the questionnaires for the Southern region is
<br />99,699, which is 56% of the population difference for the Northern region of 177,426 listed on the table in the
<br />attached SDO report.
<br />The main purpose of the questionnaires was to review the mix of six water sources used by municipal entities to
<br />meet deliveries. The six water sources used in the CPFD analysis are (1) transbasin imports, (2) nontributary
<br />groundwater, (3) agriculture to urban conversion, (4) wastewater reuse /exchange, (5) new native South Platte flow
<br />development and (6) water conservation. The questionnaires provided data on acre -feet of deliveries for sources (1)
<br />through (5) for the initial 5 -year period of 1998 -2002 and a recent/current 5 -year period of 2004 -2008. The
<br />questionnaire data for native South Platte flows was for total deliveries of native South Platte water where as
<br />described below river call data was used to determine the use of new junior South Platte water rights. The
<br />computation of the sixth source, water conservation, is done differently as described below because water
<br />conservation represents a savings of the other sources, which can then be used for new demands from population
<br />growth. The original CPFD had assumptions for the % mix of these 6 sources for the initial period. From the data,
<br />a difference (both in acre -feet and percent) in the use of the 6 sources between the initial period and the recent
<br />period is determined which is then used to adjust the original assumptions on the % mix. The revised % mix of the
<br />6 sources will be used for the CPFD analysis on accretive /depletive effects since the start of the Program on January
<br />1, 2007. Table lA is a summary by region of the questionnaire data and Table 1B computes the revised % mix of
<br />water sources.
<br />The Table 1 A analysis of two of the water sources (water conservation and new South Platte flow development)
<br />requires further explanation. It is necessary to establish the level of water conservation for the initial period and the
<br />recent period, where recent period water conservation will be initial period water conservation plus any additional
<br />water conservation realized more recently. The Colorado Water Conservation Board -CWCB has completed an
<br />extensive review of water needs and supplies for the entire state called the Statewide Water Supply Initiative
<br />(SWSI), which reviewed M &I water conservation activities in depth. The SWSI report is discussed below.
<br />Through the questionnaires and discussions, it is apparent that municipalities continue in a drought scenario water
<br />supply planning mode due to the extended drought that began in 2000. Increased water conservation activities are
