The <br />consumptive use and lagged stream depletions from each site are summarized in the attached <br />Tables. <br />Replacements <br />Upper Poudre River <br />Replacement Sources Projected <br />2007 Yields <br />acre-feet Comments <br />Little Cache La Poudre Ditch 3.72 2 shares total, 0.1 shares a lied to this Ian <br />Ci of Fort Collins Lease 7.17 <br />Tri-Districts Lease N/A Annual Lease if necessa <br />Little Cache La Poudre Ditch <br />The two Little Gache La Poudre Ditch shares were historically used to irrigate 73.5 acres of pasture <br />grass. Using aBlaney-Griddle analysis the potential crop consumptive use for the 73.5 acres of <br />pasture grass was determined to be 105.1 acre-feet. Assuming a 10% ditch loss and 55% farm <br />efficiency the dry year consumptive use was determined to be 74.4 acre-feet. Aggregate will <br />utilize 0.1 shares of the Little Cache shares to this plan. The consumptive use credit associated <br />with 0.1 shares is 3.72 acre-feet. <br />
