The water quality of the Box Elder Ditch is appropriate for its end uses. The project should not have a negative impact on water quality. The water will be pumped into a holding pond before being gravity fed back to the Poudre River which will allow some settling to occur. Project Description - Analysis of Alternatives & Selected Alternative Analysis of Alternatives The Company has several options for augmenting its wells. "Do Nothing " Alternative One is to maintain the status quo. This option is not desirable due to the uncertainty in futture availability and cost. Maintaining the status quo is seen as loss of current well use in the future. The "do nothing" alternative is therefore not an option if the wells are to continue operating. Additional Water Rights The Company has the option to purchase additional water rights as rental water, however neither of these options gives the Company the security in the system that a reservoir provides. The Company is amending its current augmentation plan to includes a number of capital shares. of The New Cache La Poudre Irrigating Company and The Cache La Poudre Reservoir Company„ assigned to the plan by the well owners, to be changed in use to include augmentation uses. The consumptive use credit of the senior water represented by these shares of capital stock are anticipated to be the guarantee to the river that past pumping depletions can be met. Timnath Flatiron Reservoir Timnath :Flatiron Reservoir option is desirable because of it's location in relation to the New Cache La Poudre Irrigating Company and the depletions associated with the augmentation plan of the Lower Poudre Augmentation Company. The river diversion structure of the New Cache La Poudre Irrigating Company is Just downstream of the Timnath Flatiron Reservoir less than two miles with no intervening diversions. Thus, any water released out of Timnath Flatiron Reservoir can be left in the river to replace well depletions in Reach 1 and 2 of the augmentation plan, taken down the canal and released to reaches 3 or 4 of the augmentation plan, or taken to other facilities within the service area. Thus, the location of the Timnath Flatiron Reservoir makes it a very integral structure in the management of waters for the Lower Poudre Augmentation Company. The option of purchasing the Timnath Flatiron Reservoir also made the most economic sense and was the most secure option available to the Company. Several options were evaluated for infrastructure on this site. One looked at bringing water in from the Boxelder Ditch at the southwest corner of the site. This option would require pumping the water a minimum of 1.000 feet and the transmission of the water over a commercial site. Another option looked at a direct diversion from the Cache la Poudre River. This site had issues with access due to the sites separation from the river at the north by City of Fort Collins open space. The south section of the site is heavily wooded and could potentially require wetland review and additional permitting. It is also questionable if the site could draw the needed volume of water from the river„ This option was therefore not recommended. Taking water from the Fossil Creek Inlet Canal was also 5
