Upper Poudre Combined SWSP <br /> pp Page 5 of 10 <br /> June 18, 2014 <br /> acre-feet of consumptive use credit to be used for replacement of out-of-priority depletions under this <br /> SWSP. <br /> The maximum monthly and annual volumetric farm headgate diversion limits for the subject <br /> 7.61 shares, based on the average monthly and annual farm headgate deliveries determined for the 5.75 <br /> shares, are shown in Table D below. <br /> Table D - Maximum Volumetric Farm Headgate Diversion Limitations (acre-feet) <br /> Apr May Jun Jul Aug Sep Oct Annual <br /> 5.75 shares 2.94 41.78 53.79 56.73 48.88 31.47 4.73 240.31 <br /> Pro-rated for 7.61 shares 3.89 55.30 71.19 75.08 64.69 41.65 6.26 318.05 <br /> It is anticipated that 219.25 acre-feet of farm headgate delivery associated with the Taylor Et <br /> Gill Ditch shares will be delivered to the Upper Poudre Recharge Ponds (WDID 0302004) during the <br /> period of May through October. Daily deliveries of the shares will be measured and any excess <br /> deliveries wilt be sent directly back to the river without claiming augmentation credit. Excess water <br /> will be returned to the river via the Taylor Et Gill Wasteway, as described in more detail below. <br /> Evaporative losses from the water delivered to a series of three recharge ponds is estimated to total <br /> 3.42 acre-feet for this plan period, based on a maximum recharge pond surface area of 1.5 acres. The <br /> net recharge accretions were tagged to the river using the AWAS model with the following parameters: a <br /> distance (X) from the centroid of the exposed ground water surface to the river of 2,300 ft; a width (W) <br /> of the aquifer of 6,500 ft; a transmissivity (T) of 160,000 gpd/ft; and a specific yield (S) of 0.2. Taylor Et <br /> Gill Ditch shares have been diverted into the recharge ponds to produce accretions to the stream for <br /> replacement purposes for the subject sites under previous SWSPs since 2004. Lagged recharge <br /> accretions from past and projected (2014) deliveries are anticipated to total 206.91 acre-feet during <br /> this plan period. The return flow obligations associated with the use of the Taylor Et Gill Ditch shares <br /> will be calculated using the return flow factors shown in the attached Table 4, column E. Return flow <br /> obligations during the summer period of April to September will be calculated by multiplying the <br /> monthly delivery to recharge by its respective monthly factor. Obligations during winter months <br /> (October through March) will be calculated by multiplying the previous year's annual delivery to <br /> recharge (172.78 acre-feet for 2013) by its respective monthly factor. Any farm headgate delivery of <br /> the Taylor Et Gill Ditch shares made in October will be included in the October return flow requirement <br /> in addition to the amount calculated based on the monthly return flow factor. Return flow obligations <br /> wilt be calculated based on the actual timing of diversions. After accounting for return flow obligations, <br /> the Taylor Et Gill Ditch shares delivered to recharge are projected to generate a total of 102.77 acre- <br /> feet of available replacement water during 2014. <br /> The remaining 98.89 acre-feet of farm headgate delivery associated with the Taylor Et Gilt Ditch <br /> shares wilt be delivered directly to the Cache La Poudre River for replacement purposes during the <br /> period of April through August. Deliveries will be made at the Taylor Et Gilt Wasteway located as shown <br /> in Figure 1. The wasteway is a headgate on the ditch that flows to an approximately 8.5-acre pond. <br /> The delivery point is on the north side of this pond and from the pond the water will flow to the Cache <br /> La Poudre River. Typically, any time water is being delivered to the pond, water from the pond wilt <br /> spill into the Cache La Poudre River; however, in the event that deliveries are made while water is not <br /> spilling from the pond, the Applicant is required to notify and coordinate with the water commissioner <br /> to ensure that depletions are replaced in time, location, and amount. All deliveries wilt be recorded <br /> daily and any excess deliveries will be sent directly back to the river without claiming augmentation <br /> credit. The return flow obligations associated with the use of the Taylor Et Gill Ditch shares will be <br /> calculated using the same return flow factors as shown in the attached Table 4, column E. Return flow <br /> obligations during the summer months will be calculated by multiplying the monthly delivery to the <br /> river by its respective monthly factor. Obligations during winter months will be calculated by <br />
