from Fossil Creek storage. The Poudre Prairie decree established formulas for calculating surface <br /> return flows obligations and subsurface return flow obligations for use of GIC direct flow water <br /> and Fossil Creek Reservoir water.Projected monthly yields and return flow obligations for the <br /> share of GIC to be used in this SWSP are provided in Table 3.Return flow obligations in excess <br /> of the monthly yield will be met with leased wholly consumable supplies from the City of <br /> Greeley.Monthly reporting to the Divison of Water Resources will be updated with actual yields <br /> designated by the GIC and return flow obligations will be recomputed as needed. <br /> Loloff Construction Inc.has entered into a one-year rental agreement with the City of Greeley for <br /> the use of 12.75 ac-ft of wholly consumable supplies deliverable to the lower Poudre River at <br /> locations defined in the rental agreement(attached). A monthly water balance has been developed <br /> for all depletions and replacements,as shown in Table 4 and is proposed to serve as the template <br /> for the monthly accounting to be submitted to the Division of Water Resources. <br /> It is anticipated that the augmentation deliveries from both the GIC and the City of Greeley will <br /> occur in the immediate vicinity of the Poudre River reach impacted by operations at the Loloff <br /> Pit.The Greeley waste water plant is approximately 0.42 miles upstream of the Ogilvy Ditch <br /> headgate and the 16th Street augmentation return is approximately 1.8 miles downstream of the <br /> Ogilvy Ditch headgate(distances based upon Figure 4.1, South Platte Water Conservation Project <br /> —Poudre River Operation and Exchange Model, 1996,NCWCD) <br /> Long-Term Augmentation: <br /> The Planned reclamation of the site is lined pit storage by constructing a slurry wall around the <br /> mining area.The exposed water surface associated with the reclaimed reservoir will be <br /> approximately 40 acres.As a slurry wall will be constructed around the mining area,there will be <br /> no long-term evaporative losses of groundwater from exposed water surface at the site. It is not <br /> currently known when the slurry wall will be installed at the site.There is no pre-1981 exposed <br /> water surface at this site. Currently 1 share of Greeley Irrigation Company(Certificate 3391)and <br /> 1 share of New Cache La Poudre Irrigation Company(Certificate 4635)have been dedicated <br /> toward a future permanent augmentation plan and financial warranty has been provided to the <br /> DRMS in the form a letter of credit. The total financial warranty on file with the DRMS is <br /> $689,552.00(See attached letter from the DRMS). <br /> Sincerely, <br /> Paul Weiss,P.E. <br /> Principal <br /> Williams and Weiss Consulting <br /> WWC Water Resource Engineering <br />
