  <br />Mr. Paul Bruss, P.E.  <br />April 12, 2018  <br />Page 3 of 6  <br />  <br />  <br />  <br />Historical phreatophyte and effective precipitation were determined to partially offset gross            <br />evaporation at the site.The credit from historical phreatophyte consumptive use was             <br />calculated to be 19.5 acre-feet per year from 5.6 acres of equivalent 100%canopy cover                <br />native vegetation in Phase 1,and 17.5 acre-feet per year from 5 acres of 100%canopy cover                  <br />native vegetation in Phase 7.Effective precipitation was claimed on the remaining 26.4 acres               <br />of exposed surface area, and was calculated as 70% of precipitation.  <br />  <br />REPLACEMENT  <br />  <br />The replacement water is proposed to be from three sources.The first is excess credits from                 <br />the Hamp-Bell Ditch water rights changed in Division 2 Water Court case no.03CW8 and                <br />subject to the April 2004 agreement (amended March 2007)between Transit Mix and Pueblo               <br />Board of Water Works (“PBWW”).The second is consumable water leased from the PBWW.               <br />Transit Mix currently has a lease with Pueblo that will provide 120 acre-feet of fully                <br />consumable water annually through September 30,2022.The third is 60 shares of Twin Lakes                <br />Reservoir water owned by Transit Mix that are primarily used for Transit Mix’s Grisenti Pit                <br />under a separate SWSP (ID 4625),but typically provide excess water available for this SWSP,                <br />should it be needed.For purposes of this SWSP,only the transmountain component of the                <br />subject Twin Lakes Reservoir shares may be considered available to be used as a replacement                <br />supply herein.  <br />  <br />The excess credits from the Hamp-Bell Ditch water rights were changed in Division 2 Water                <br />Court case no.03CW8 to commercial and augmentation uses.As decreed by the Division 2                <br />Water Court in case no.12CW102,PBWW obtained the right to store the Hamp-Bell Ditch                <br />credits changed in case no.03CW8;therefore,Transit Mix is no longer responsible for               <br />replacing the winter return flow obligation associated with the Hamp-Bell Ditch water rights,              <br />and will only be entitled to use the net excess credits after full augmentation of Chain of                  <br />Lakes depletions and replacement of winter delayed return flows,which will average             <br />approximately 10.0 acre-feet annually.The projected depletions,credits,and releases           <br />subject of this SWSP are shown on the attached Table 5.   <br />  <br />The State and Division Engineers have reviewed the plan and the adequacy of each source of                 <br />water provided for use as augmentation water,including,where necessary,the historical             <br />consumptive use of each water right,and return flows from diversion of waters imported into                <br />the Arkansas River Basin or other fully consumable waters proposed for use as augmentation               <br />water.   <br />
