Jackson Lake Dam
· Current Discharge = 3,100 cfs.
· Today (7/8) discharge will decrease to approximately 2,300 cfs.



The Upper Snake reservoir system is currently 91% full (3,661,459 acre-feet out of 4,045,695 acre-feet). From June 30th to July 6th unregulated inflow above Heise, ID, measured 109% of average. System inflows are receding at a moderate pace and outflows from the reservoirs in the system will be governed by natural flow and storage flow deliveries from this week until the late fall months when outflows will be adjusted down to winter flows in the October timeframe.

Jackson Lake’s discharge is being decreased today to the target summer flow from Jackson Lake Dam. The flow may be adjusted slightly during the summer months to target reaching a storage of approximately 577,000 acre-feet by October 1st.
