Spring rain storms will have made a big difference when Magic Valley farmers harvest their crops this fall. That moisture has kept many southern Idaho reservoir levels from dwindling badly this growing season but will not be enough to take all water worries from farmers.
Projections before the spring rains were dire. In early April, the reservoir system was at 59% capacity, and Jackson Lake and Palisades Reservoir, two of the headwater reservoirs of the Snake River, were not expected to fill. Many reservoirs are expected to be almost empty at the end of the growing season, with American Falls Reservoir expected to be at about 10% and Palisades Reservoir expected to be about 5-10% full.
