Change in flow from the King Pond Settling Facility Recommendations 1. For the Developer to monitor water levels and fish downstream of the King Pond Settling Dominion Diamond Ekati ULC Facility beginning the year when no water will be pumped from the King Pond Settling Facility to downstream watercourses. This is to ensure that water levels will be sufficient for fish spawning and eggs hatching. DFO also recommends that the Developer provide details with respect to potential actions that will be taken should low water levels be detected. 8
