Water Availability <br />st <br />The irrigation season under the New Cache system generally begins between the 1 <br />ththth7 <br />and 15of May and ends between the 10and 20of September.New Cache will <br />divert its river rights first when available, which is typically in the spring and early <br />summer when stream runoff is at or near peak conditions (i.e., May and June) and <br />senior rights downstream are not calling. New Cache refers to the season of direct flow <br />diversions (May through early July) as their “river run” season. When direct flow or river <br />water is unavailable, New Cache will begin their “reservoir run” or delivery of their <br />8 <br />reservoir or other supplemental sources. <br />In most years, New Cache is able to continue some limited diversions under their direct <br />flow water rights even during the “reservoir run.” New Cache refers to direct flow <br />diversion diverted during the reservoir run as “river credits.” According to the New <br />Cache website, river credits are calculated from the portion of the water being delivered <br />during reservoir season that is river or direct flow decree water. We understand that the <br />Water Commissioner calculates total system river credits on a weekly basis and that <br />New Cache allocates those credits to its shareholders on a pro-rata basis. River credits <br />provide some supplies to shareholders after the primary river run ends in early July, but <br />on a grand scale they tend to make up a smaller portion of total irrigation diversions <br />during the months of August, September and October. <br />If New Cache shares are acquired in the future by the Town for direct irrigation, Windsor <br />can anticipate that on average this source will be available to meet nearly all water <br />demands in May and June, but only a fraction of total irrigation demand in all other <br />months. <br />If CLP Reservoir shares are acquired in the future by the Town for direct irrigation, <br />Windsor can anticipate that on average this source will be available to meet demands <br />when New Cache or other direct flow shares are unavailable. <br />Timing of deliveries for both New Cache and CLP Reservoir is less relevant if the <br />shares are changed and stored in Kyger Reservoir. Storage within Kyger Reservoir <br />would allow the water rights to be “retimed” as needed, e.g., stored when they are <br />available and released at a later date when needed. <br />Delivery and Consumptive Use <br />The table below includes the approximate per share river diversion/reservoir releases, <br />farm headgate delivery volumes and consumptive use values for New Cache’s direct <br />flow water rights and CLP Reservoir’s storage rights. This information was obtained <br />from the January 2010 Draft Ditch-Wide Engineering Report. <br />7 <br />Source of information: SPDSS New Cache memo <br />8 <br />Source: SPDSS New Cache memo, New Cache website <br /> <br />
