City of Westminster <br />The majority of Westminster’s raw water suppl y originates from Clear Creek and flows to <br />Standley Lake through three main canals that di vert water from the nor th bank of Clear Creek <br />near Golden: the Farmer's High Line Canal, th e Croke Canal, and the Church Ditch. The City <br />owns shares or inches in each of these canal companies. The Farmers’ High Line Canal and <br />Reservoir Company has been a part of Westmi nster's water supply since the 1950s. Westminster <br />presently owns or controls a majority of the shares in the Company. The Church Ditch inches <br />were acquired by Westminster beginning in abou t 1960. The City also owns shares in the <br />Standley Division of FRICO. The City owns the majority of shares in the Kershaw Ditch that <br />diverts from the north side of Clear Creek at Tennyson Street and the Manhart Ditch that diverts <br />water from the north bank of Ralston Creek about one mile upstream of its confluence with Clear <br />Creek. Water derived from the Kershaw and Manhart ditches is used for water rights exchanges. <br />Westminster owns Jim Baker Reservoir (aka Happe Ponds, Structure ID 0703336, about 900 ac- <br />ft capacity) and capacity in Thor nton's West Gravel Lakes an d uses these reservoirs for <br />exchanges and augmentation. In addition, Westmi nster owns water rights in the Last Chance <br />Ditch that diverts out of Coal Creek. Westminste r’s portion of Coal Creek is delivered into the <br />Kinnear Ditch Pipeline for de livery to Standley Lake. <br />Prior to accumulating shares in the Church D itch, Farmers’ High Line, Kershaw Ditch, and <br />Standley Lake Division on Clear Creek and in the Manhart Ditch on Ralston Creek, Westminster <br />used non-tributary wells, contract water from Denver Water Board, and direct flow from the <br />Kershaw Ditch for its municipal water supply. Wa ter from the Denver Water Board Contract is <br />now delivered to Standley La ke via the Kinnear Pipeline. <br />Westminster was asked for its current pro-rata ownership of major wate r rights in the Clear <br />Creek basin and specifically requested that information not be tabulated. <br />The Westminster annual demand is currently ab out 21,000 ac-ft. Westminster’s anticipated build <br />out demand is 30,000+ ac-ft with future growth occurring in the Big Dry Creek basin. These <br />demands include contract deliveries to Federal He ights and unincorporated areas of portions of <br />Adams County and Jefferson County. Westminster’s pr imary treatment plant, the Semper facility <br />(48 MGD capacity), came on-line in the 1970s. The Northwest WTP (20 MGD capacity), which <br />came on-line in 2000, is typically used to deliver summer peaking supplies. Wastewater from use <br />in the Little Dry Creek basin is treated and di scharged from the Metro WWTP. Wastewater from <br />use in the Big Dry Creek basin, which accounts for ove r half of Westminster’ s effluent, is treated <br />at Westminster’s Big Dry Creek WWTP. The C ity’s reuse plant in the Big Dry Creek basin, <br />came on-line in 2000. Current reuse dema nds are about 1,000 ac-ft per year. <br />Winter – The City also has a 2 MGD contract fr om Thornton that is de livered from Thornton’s <br />potable system into Westminster’s potable syst em. The City diverts FRICO water direct through <br />the Croke Canal supplemented with Standley Lake storage releases, as necessary, to meet its <br />remaining winter demand. <br />Summer – The City takes water from its Clear Creek changed ditch shares and exchanges into <br />and through Standley Lake, with any remaini ng demands met with Standley Lake storage <br />releases. <br />22 of 24 <br />
