• Monthly updates of the water accounting were submitted to the division engineer to verify that all <br /> out-of-priority well depletions were augmented by the LSPWCD replacement supplies. These <br /> replacement supplies consist of both recharge accretions and pumping of augmentation wells <br /> directly back to the river. Inflows to groundwater recharge ponds result in accretions to the river <br /> lagged over a period of time. Augmentation wells are pumped directly to the river through ditches <br /> and creeks on days of river call to replace the remaining depletions not covered by recharge <br /> accretions. The use of augmentation wells also causes future depletions that must be replaced if <br /> out-of-priority. <br /> In 2005 accounting was completed for member wells by the district to assess members a dollar per <br /> acre-foot charge for depletions at the river during the period of April 18`through October 15th. <br /> Replacement supplies were leased for augmentation in 2005 using the same process. A list of these <br /> replacement supplies and their accounting is attached in appendices 1 and 2. Augmentation well <br /> credits for 2005 are listed in appendix 2 and recharge accretions are listed in appendix 1 for 2005. <br /> The lease rate in 2005 for well augmentation was 25 dollars per acre-foot for both call and non-call <br /> periods. The individuals listed in the upper section of the appendices are LSPWCD members who <br /> have developed replacement supplies. LSPWCD leases these replacement supplies from their <br /> members to cover out of priority depletions from member wells and augmentation well pumping. <br /> This results in a net reduction in assessments for LSPWCD members who develop individual <br /> replacement supplies. The lease rate for replacement supplies in 2005 was 20 dollars per acre-foot <br /> for both call and non-call periods. <br /> LSPWCD paid Julesburg Irrigation District(ill))conveyance fees and leased recharge accretions <br /> • from HD(appendix 1)in 2005. The South Platte Lower River Group(SPLRG)(appendix 1) <br /> leased LSPWCD recharge accretions generated from their portion of the Town of Julesburg <br /> recharge project during the 2005 water year. In addition,LSPWCD exchanged excess <br /> augmentation water through the Liddle Ditch during 2005 at a rate of$5 /ac-ft(appendix 1). <br /> LSPWCD also paid for the electrical costs to pump the Beavers augmentation well (appendix 2). <br /> The total LSPWCD lease payment for augmentation replacement supplies was $61,552 in 2005 <br /> (Table 1). The total days of river call where LSPWCD had to replace out-of-priority well <br /> depletions during 2005 was 105 days(Appendix 1). The average number of call days on the lower <br /> South Platte River is 84 days according to information provided by CWCB. The Program per the <br /> September 2004 Guidelines also provides funds for engineering and attorney fees equal to 5%of <br /> the grant amount. Engineering/Attorney fees were calculated to be $615 in 2005. This brings the <br /> total grant for LSPWCD in 2005 to$12,926(Table 1). <br /> 2005 <br /> Lease cost of augmentation water $61,552 <br /> Number of drought call days 105 <br /> Average number of call days 84 <br /> Call day ratio 105/84=1.25 <br /> Cost reduction $61,552/1.25=$49,242 <br /> Grant amount $61,552-$49,242=$12,310 <br /> • 5%for Engineering/Attorney Fees $615 <br /> Total Grant $12,926 <br /> Table 1-2005 Drought Assistance Grant Calculations <br />
