Monthly updates of the water accounting were submitted to the division engineer to verify that all Mo g fY • Y P g out-of-priority well depletions were augmented by the LSPWCD replacement supplies. These replacement supplies consist of both recharge accretions and pumping of augmentation wells directly back to the river. Inflows to groundwater recharge ponds result in accretions to the river lagged over a period of time. Augmentation wells are pumped directly to the river through ditches and creeks on days of river call to replace the remaining depletions not covered by recharge accretions. The use of augmentation wells also causes future depletions that must be replaced if out-of-priority. In 2003 member wells were billed for gross well pumping at$9.25 per ac-ft. Individuals with replacement water for 2003 were credited by multiplying that individual's cost of well pumping by the ratio of un-replaced depletions to total depletions. The total amount owed by an individual with replacement water was calculated by adding necessary administrative fees and operational fees to the discounted well pumping cost described above. The difference between the amount that the individual would have paid (without replacement water) and the actual amount owed was the amount of leased water purchased from individuals for augmentation in 2003. For 2003, individual water leases, other recharge accretion leases, and other augmentation well expenses are listed in appendix 1. In 2003 the lease rate was 20 dollars per acre-foot on days of call and 15 dollars per acre-foot on days of non-call. In 2004 accounting was completed for member wells by the district to assess members a dollar per acre-foot charge for depletions at the river during the period of April 1st through October 15th. • Replacement supplies were leased for augmentation in 2004 using the same process. A list of these replacement supplies and their accounting is attached in appendices 2 and 3. Augmentation well credits for 2004 are listed in appendix 2 and recharge accretions are listed in appendix 3 for 2004. The lease rate in 2004 for well augmentation was 20 dollars per acre-foot for both call and non-call periods. The individuals listed in the upper section of the appendices are LSPWCD members who have developed replacement supplies. LSPWCD leases these replacement supplies from their members to cover out of priority depletions from member wells and augmentation well pumping. This results in a net reduction in assessments for LSPWCD members who develop individual replacement supplies. LSPWCD leased recharge accretions from the Julesburg Irrigation District(JID) (appendices 1 and 3) and the South Platte Lower River Group (SPLRG) (appendices 1 and 3) in the 2003 and 2004 water years. LSPWCD also leased water from the Beavers augmentation well where the lease consists of the payment by the LSPWCD for the electrical costs from pumping and the payment of the conveyance fee to JID for delivery of the pumped water through JID ditches (appendices 1 and 2). The total LSPWCD lease payment for augmentation replacement supplies was $51,886 in 2003 and $36,647 in 2004 (Table 1). The total days of river call where LSPWCD had to replace out-of- priority well depletions during 2003 was 159 days and in 2004 was 190 days (Appendix 1). The average number of call days on the lower South Platte River is 84 days according to information provided by CWCB. The Program per the September 2004 Guidelines also provides funds for engineering and attorney fees equal to 5% of the grant amount. Engineering/Attorney fees were calculated to be $1,224 in 2003 and $1,022 in 2004. This brings the total grant for LSPWCD in the years 2003 and 2004 to $47,165 (Table 1).
