Thompson River and transbasin water supplies are generally used for peaking purposes to <br />supplement the Cache la Poudre River supplies. Water supplies from the C-BT units <br />(approximately 25 percent) and the GLIC shares (approximately 30 percent) are available over <br />the irrigation season, generally from April through October. <br />Winter <br />• Winter demands (November-March) are currently met from the 7 cfs of 70P releases and <br />the 12.5 cfs of senior water rights transferred from the Whedbee Ditch and Boyd <br />Freeman Ditch to the Bellvue Treatment Plant. <br />• Residual winter demands are generally satisfied from <br />- Transbasin water stored in Horsetooth Reservoir and <br />- Secondly from storage releases from Milton Seaman Reservoir. <br />• The City required more transbasin water supplies in the winter prior to operation under <br />the JOP due to the reduced amount of high mountain storage releases before 1994. The <br />City's transbasin water supplies are generally initially needed at the end of the winter <br />season. <br />• Future deliveries of transbasin water during the winter will be conveyed through the PVP. <br />• During the winter, the reusable portion of the City's WWTP outflow generally satisfy its <br />winter return flow obligations for its changed water rights, and for replacement <br />requirements for the ground water well augmentation plans developed in the 1990s. <br />- Additional replacement water, if necessary, is available from transbasin supplies or <br />in-basin storage. <br />• The City generally stores water in Milton Seaman Reservoir during the winter under the <br />upstream storage statute against the senior downstream Timnath Reservoir storage right. <br />Water stored out of priority during the winter is then released during the spring if <br />Timnath Reservoir or other downstream, senior storage rights do not fill. <br />Summer <br />The City's upper basin water supplies, its direct flow rights at the Bellvue Treatment <br />Plant, and the changed water rights are generally sufficient to meet potable water <br />demands during the summer (April-October) with peaking supplies coming from the <br />City's shares in the GLIC system and the C-BT and Windy Gap units. <br />The City's adjudicated direct flow and changed water rights are summarized in Table 3 <br />and Table 4, respectively. Changes to the City's additional share ownership in these and <br />other ditches are currently pending in water court. <br />The City generally operates the Boyd Potable Treatment Plant, located in the Big <br />Thompson River basin, when its total demands exceed 20 mgd. The Boyd plant receives <br />water directly from Lake Loveland at an elevation that corresponds with 5,000 ac-ft of <br />active storage capacity above the Lake Loveland outlet works. To access this water year- <br />round, the City generally provides 5,000 ac-ft of C-BT water to compensate Lake <br />Loveland contract rights holders for the storage capacity Greeley requires below its outlet <br />pipe in Lake Loveland. <br />- The City of Greeley's water supply holdings are such that it generally does <br />not have enough carry-over storage for its water supplies during average and <br />wet years. Therefore, the City's 5,000 ac-ft delivery of storage water to Lake <br />Loveland generally occurs through the transfer of excess transbasin supplies <br />from the C-BT system to Lake Loveland at the end of the summer. <br />Page 19 of 21 <br />
