Spring time mountain snow melt caused the Methow River to rise to a minor flood level and fluctuate slightly above and below the Flood Stage during the second and third weeks of May. No buildings or structures were threatened by this flood, however minor flooding of secondary roads and bottom lands near the river between Pateros and Mazama resulted.
