West Elk Mrne water rights were harmed as a consequence of storing water in the stunps. Furthermore, North Fork minimtun stream flows were maintained during this period. • 3. There will likely be no net North Fork depletions, because mine discharges (including the fault water inflows) will equal or exceed surface diversions. Further, MCC will continue to ensure that any North Fork water which is diverted when the Mount Gunnison Pipeline is out of priority will be fully replaced by its other North Fork replacement water (i.e. Fire Mountain Canal Leased water from Fast Beckwith No. 1 Reservoir, etc). 4. After the new pumping facility is operational, there will continue to be no affect to senior water rights diversions in the North Fork because the pumping facility will contribute flows to the North Fork well upstream of these diversions, as well as, MCC's intake gallery. Also, any out-of-priority diversions will continue to be replaced with releases from East Beckwith No. 1 Reservoir or MCC's other North Fork water rights. 5. After analyzing the 1996 North Fork diversions and return flows, WWE concluded that there were no Section 7 (of the Endangered Species Act) issues that arose from MCC's management of the fault water inflows, including use of the sealed panels sumps.
