Supply Canal. The North Poudre Canal and its laterals cross Stonewall Creek, Spring Creek, <br />Dry Creek, and Boxelder Creek as it delivers water throughout the NPIC System. By virtue of <br />decreed water rights, flows can be intercepted from Dry Creek and Boxelder Creek. The North <br />Poudre Canal is located entirely within Larimer County within Water District 3. <br />Direct flow water in the North Poudre Canal is used predominantly for irrigation of lands under <br />the NPIC System. North Poudre Canal direct flow water rights have been changed to allow all <br />uses (storage, municipal, commercial, industrial, recreation, fishery, fire, domestic, <br />augmentation, and wild and scenic river uses). <br />The North Poudre Canal is predominately earth lined. In the last few years, NPIC has begun <br />enclosing in pipe those stretches of the ditch that exhibit considerable seepage. Along the <br />Buckeye Lateral, approximately 2,000 feet of ditch has been enclosed. NPIC plans to enclose <br />more stretches of ditch in the future. <br />Length: The total length of the North Poudre Canal including the Livermore Lateral, Buckeye <br />Lateral, and Boxelder Lateral is approximately 20 miles. <br />Capacity: In 1951 a maximum daily diversion of 304 cfs was recorded through the North <br />Poudre Canal. However, NPIC reported that the current capacity of the Livermore <br />Lateral is approximately 175 cfs and the Buckeye Lateral capacity is approximately 100 <br />cfs. Daily diversion records back to 1984 support a reduction in capacity of the North <br />Poudre Canal. The capacity of the North Poudre Canal is a constraint on the ability to <br />convey direct flow and storage rights. <br />Measurement Device: Diversions through North Poudre Canal are measured at a 12-foot <br />Parshall flume equipped with a Stevens recorder located at the downstream side of the <br />tunnel. These records reflect the direct flow and storage diversions to the North Poudre <br />Canal Reservoir System. <br />Conveyance Efficiency: System-wide conveyance losses in the NPIC System, not including the <br />Fossil Creek Division, are reported to be 16 percent (CWR&PDA, 1987). According to <br />NPIC, system losses throughout the NPIC System are greater than 50 percent. NPIC <br />defines system loss as all possible losses throughout the storage and distribution system <br />including but not limited to conveyance loss, evaporative loss, reservoir seepage, and <br />incidental uses. <br />Return Flow Locations: Return flows from the North Poudre Canal are intercepted at the North <br />Fork Cache la Poudre River, at the Main North Poudre Supply Canal, and in the lower <br />Stonewall Creek, Spring Creek, Dry Creek, and Boxelder Creek drainages. <br />The North Poudre Canal can intercept flows from Dry Creek and Boxelder Creek by <br />virtue of decreed water rights. Flows in Stonewall Creek and Spring Creek are bypassed <br />under the North Poudre Canal. Flows in Campbell Springs are bypassed under the canal <br />down to Dry Creek Reservoir. <br />NorthPoudreMemo.doc 10 of 29 <br />
