It is a s'#39;s throw away from Glacier National Park's west entrance. ), helps reduce uncertainty in technical pricing with high-precision, per-location risk assessment. The Corps released a draft environmental assessment this month that calls for reducing maximum water levels in the dam's reservoir by 5 feet to reduce pressure on the spillway's gates. At 564 feet, the Hungry Horse Dam is the highest in Montana, holding back 3.5 million acre-feet of water in its reservoir.
