Aggregate Industries South Platte Combined SWSP January 30, 2019 <br />Plan IDs 3614, 4773, 3624, 4772, 4616, 3437, 3376, 3650, 3668, and 5475 Page 11 of 21 <br /> <br />shares for 2018 has been estimated from a dry-year farm headgate delivery of 2.64 acre-feet per <br />share or approximately 164 acre-feet for all 62 shares. After accounting for return flow obligations, <br />the total consumptive use credit for the 62 shares is projected to equal 110.97 acre-feet in 2019. In <br />the event the Fulton Ditch goes into Sections, the Applicant has sufficient alternative replacement <br />supplies in the form of shares in the Brighton Ditch, as described below, to make up any temporary <br />shortfalls. <br />Brighton Ditch <br />Pursuant to a March 4, 2010 Water Lease with the City of Westminster, Aggregate has the <br />right to use 1.038 shares in the Brighton Ditch Company owned by the City of Westminster for <br />augmentation purposes. The lease is currently valid through March 4, 2020. The subject 1.038 <br />shares were changed in case no. 2016CW3186 from irrigation use to direct flow and storage or all <br />beneficial uses of the municipal water system of Westminster. The use of the subject shares for <br />replacement purposes in this SWSP was not decreed in case no. 2016CW3186; however, the decree <br />entered in case no. 2016CW3186 included a provision that Aggregate’s continued use of the subject <br />shares be governed by the terms and conditions of the decree. The decree entered in case no. <br />2016CW3186 relied on a parcel-specific analysis of the historic consumptive use of the subject water <br />rights, with a study period of 1950 through 2001. The total shares include 4/6th (0.667) of a share <br />historically used to irrigate the Broncucci (aka Wattenberg) Property. An average of 42 acres of <br />pasture grass were irrigated by controlled flood irrigation. The engineering study commissioned by <br />Westminster for case no. 2016CW3186 found the average historical consumptive use for the 0.667 <br />Brighton ditch shares used on the Broncucci Property to be 82.5 acre-feet. <br />The other 0.371 shares were historically used to irrigate the Haake Property, along with 5.75 <br />shares of the New Brantner Extension Ditch Company. Irrigated portions of the Haake Farm ranged <br />from 92.3 to 111.8 acres from 1950-2001. During the study period, between 10.7 and 11.3 acres of <br />dry beans (prior to 1960) and corn (1960 on) were irrigated by the Brighton Ditch shares only; 20 <br />acres of pasture grass and between 14.2 and 20.1 acres of dry beans (prior to 1960) and corn (1960 <br />on) were irrigated by the New Brantner Ditch shares only; and between 49 and 61 acres of furrow <br />irrigated corn and flood irrigated pasture grass were irrigated by both the combined Brighton Ditch <br />and New Brantner Ditch water supplies. The engineering study commissioned by Westminster for <br />case no. 2016CW3186 found the average historical consumptive use attributable to the 0.371 <br />Brighton Ditch shares used on the Haake Property to be 67.85 acre-feet. <br />The total average historical consumptive use for the subject 1.038 shares is therefore 150.35 <br />acre-feet per year (144.85 acre-feet per share). Aggregate will utilize the entire 1.038 shares for use <br />in this plan. The use of the Brighton Ditch shares in this plan must comply with the terms and <br />conditions of the 2016CW3186 decree, including the volumetric limits identified in paragraph 35.D of <br />the decree and summarized in the table below. <br /> <br /> Apr May Jun Jul Aug Sep Oct Annual <br />Max Monthly and Annual Limits 59.7 96.3 96.3 106.6 97.8 56.8 52.3 458.0 <br />20-Year Limits 458 1,073 1,355 1,598 1,375 879 425 7,163 <br /> <br />For the purposes of this SWSP, you have estimated the expected credit for the Brighton Ditch <br />shares from a dry-year farm headgate delivery (using a 25% ditch loss, consistent with case no. <br />2016CW3186) of 334 acre-feet per share, or 343.60 acre-feet for all 1.038 shares for the period of <br />April through October. This amount is less than the 20-year average annual limit of 358.15 acre-feet <br />(7,163 acre-feet ÷ 20 years), and therefore is acceptable.
