[191 Number of days there was a call on the South Platte River.Conservatively projected to have a call for the entire SWSP period.
[201 Out-of-priority depletion equals the fraction of the total net depletion that occurred when there was a call on the South Platte River,equal to[18]*[29]/#of days in month.
[21] RMCC's Fulton share deliveries at Brighton's Midland or 124th Ave augmentation stations,as reported by Brighton.Monthly volume is limited to the average monthly values given in SWSP Table 3,
column[7].
[22] Fulton Ditch historical consumptive use(HCU)replacement credit.January through March equal to the total 2015 Fulton Ditch delivery multiplied by negative 1 and the return flow factors given in the
April 8,2015 SWSP approval letter.April through October equal to the Fulton Ditch delivery multiplied by 1 minus the return flow factors given in SWSP Table 3,column[10].November and
December equal to the total 2016 Fulton Ditch delivery multiplied by negative 1 and the return flow factors given in SWSP Table 3,column[101.
[23] Fulton Ditch return flow replacement requirement equal to[21]minus[22]multiplied by the fraction of the month with a downstream river call.
[24] Total replacement requirement is the total of the out-of-priority depletion and the Fulton Ditch return flow obligation,equal to[21]+[23].
[251 Stored Fulton Ditch credits released to South Platte River in order to replace depletions.
[26] Required release of stored Fulton Ditch credits to the South Platte River in order to replace the given month's depletions(or any remaining replacement requirement from the prior month,equal to[24]-
[25]+[31]if there is water in storage,Col[30].
[27] Stored Fulton Ditch credits released to South Platte River in order to replace depletions.
[28] Surplus Fulton credits available for delivery to storage based on Fulton Ditch credits,[22],in excess of the out-of-priority depletions,[20].
[29] Brighton lease replacement equals[241-[25]-[27],limited to 250 ac-ft per year.
[30] RMCC's storage in Brighton's Kenneth Mitchell Lake,Erger's Pond or 124th Storage Pond.Equal to previous month's storage minus estimated evaporation and augmentation releases plus surplus Fulton
credits delivered to storage.
[31] Remaining operations replacement requirement equals previous[31]+[241-[25]-[27]-[29],if positive,otherwise equal to zero.
