Notes:
[2]Water use based upon end-of-month meter readings reported by Castle Concrete Aggregates.January 2019 end-of-month meter reading is 3,603,200 gallons.
[3a],[3b]Reclamation irrigation use at Phases 1 and 2.Water will be pumped from either Phases 1 or 2 and will be lagged useing URF factors for each phase,as described in 2020 SWSP.Irrigation uses are assumed 100%consumptive.
[4]Net Evaporation calculated as described in the 2020 SWSP renewal request
[5]Individual and total exposed ground water area reported by BBA or Castle Concrete Aggregates.Projected surface area in Phase 2 based on expected volume❑ffill during month.
[6]Individual and total evaporative depletion volume equal to net evaporation rate[4]multiplied by the exposed ground water-area[5].
[7]Unlagged ground water infiltration into Phase 2 pit resulting from cessation of dewatering and first-fill operations at the pit.Value conservatively assumes no direct delivery of water to Phase 2 via Lester-Attebery Ditch.
[8]Total unlagged mining depletions equal[1]+[2]+[3a]+[3b]+[6]+[7].
[9]Total lagged mining depletions are lagged using URF factors for each mining area,developed in IDS-AWAS employing the glover method.IDS-AWAS inputs are specified in the 2020 SWSP renewal request.
[10]Based on Historical Irrigation Credits/Debits fr❑mBBA analysis in 2010 SWSP request,continued in 2020 SWSP.
[11]Actual replacement deliveries to the Phase 1 recharge pond measured through a 2-foot rectangular weir by a continuous recorder.
[12]Historical irrigation credits delivered from Lester-Attebury Ditch to the Phase 1 pond are lagged using URFs for Phase 1,developed in IDS-AWAS employing the glover method.IDS-AWAS inputs are specified in the 2020 SWSP renewal request
[13]Replacement water delivered to Arkansas River out of Pueblo Reservoir,Pueblo West Pit reservoir or Pueblo East Pit Phase 2 reservoir via administrative exchange.Source of water is one-time lease water from PBWW.
[14]If[10]is negative,equals maximum of[9]-[10]-[12]-[13]and zero,else if[10]is positive,equal to maximum of[9]-[12]-[13]and zero.
[15]Twin Lakes Release is assessed a 10.3%transit loss based upon a loss of 0.07%per mile and a distance of 147.8 miles.Manual input
[16]Equal t❑[12]+[13]+[15]*(1-0.103)-[9]-minimum❑f[10]and zero.
