South Fork
Reclamation’s April through July volume runoff forecast for Heise is 3700 KAF, which is 114% of the 1981-2010 average. To begin advancing on updated flood control targets for Jackson Lake Dam and Palisades Dam the following changes have or will be made this week.
· Jackson Lake Dam discharge will be increased Thursday (4/5) at 10 am from the current 630 cfs up to between 1,000 cfs and 1,500 cfs.
· Palisades Dam discharge will be increased Thursday (4/5) evening into Friday (4/6) morning to go from the current 10,000 cfs up to between 14,500 cfs and 16,000 cfs by Friday morning.
· American Falls Dam discharges were increased today from 11,000 cfs to 13,000 cfs. Another increase will occur Wednesday (4/4) morning at 10 am to go from 13,000 cfs to 15,000 cfs.
The intent with respect to Palisades Reservoir is to decrease its capacity to around 50% ( Currently at about 70%) in order to contain expected run off. More increases in flow out of these three dams are possible, with weather being a factor in determining flow management.
