(Portland, OR) -- Oregon water users should expect to face a difficult summer. The USDA monthly water supply outlook shows the statewide snow-water equivalent set a new record low. The snowpack is already gone at many of the measuring sites, which is a month ahead of schedule. The probability is high that snow runoff this spring and summer will be among the lowest on record. East of the Cascades, farmers count on water from the snowpack for irrigation.
