• Loveland can divert its changed water rights at the Loveland Pipeline, to where the 202A <br />water was transferred. <br />• The City must leave 15% of its decreed rates in the ditches (see Table 2) to replace historic <br />ditch losses. <br />• Historic return flow obligations from the direct municipal use of the changed water rights are <br />addressed in the decree by WWTP returns that accrue to the river system above the <br />Hillsborough Ditch. No additional return flows are required from the direct use of the 202A <br />water. <br />Storage Use <br />• Loveland also has the option to store its 202A water, which occurred for the first time in July <br />2004 after the Green Ridge Glade Reservoir expansion was completed. <br />• In addition to the 15% ditch loss, the City must leave an additional 15% to 20% of its <br />decreed rates in the river to replace summertime return flows that do not occur when the <br />changed water rights are stored. <br />• The City must also make wintertime replacements for credits that are stored. These <br />replacements were adjudicated in the 82CW202A decree as 13% of the total stored the <br />previous irrigation season, to be diverted for municipal potable use with the effluent <br />returning to the river above the Hillsborough Ditch over the November through March <br />period. <br />Consumptive Ilse <br />The consumptive use of all in-house potable uses is estimated at 5% of the in-house diversion <br />based on treatment at a centralized sewage facility. Lawn irrigation return flows associated with <br />outside uses of water diverted through the potable treatment plant have not been quantified nor <br />adjudicated. <br />Water Supply <br />The order of operations for the City of Loveland's water resources generally follow the pattern <br />enumerated below: <br />1) Direct Flow Rights, <br />2) Transbasin Water, and <br />3) Storage Water Releases. <br />4) Ditch shares transferred and stored in Green Ridge Glade Reservoir to provide carry-over <br />storage within a season and between years. <br />• The City has exchanges decreed from any of ditches between the City's Loveland <br />Pipeline and the WWTP to facilitate the use of other storage units or non-potable <br />irrigation uses, on an as-needed basis. <br />Loveland's native water rights have generally been sufficient to meet the City's potable water <br />demands during the historic diversion season. The original direct flow rights, and the <br />requirement of a water supply dedication as a prerequisite of annexation into the City's service <br />area for more than forty years, have positioned the City well to address the growing needs of the <br />municipality. The City's adjudicated direct flow water supply sources are summarized in Table <br />City of Loveland Operating Memorandum.doc Page 13 of 15 January 5, 2005 <br />
