Farming Challenges in Okanogan Highlands near Oroville and Tonasket, Washington

Our mountain fields in the Okanogan Highlands near Oroville and Tonasket, Washington range in elevation from about 3200 feet to 3550 feet.  Elevation combined with our north central Washington winters creates a harsh environment for winter wheat.  Normal or above precipitation is critical for good yields and the drought years of 2001 - 2009 were difficult here for all farmers.

Even after wheat comes up and seems to grow thick and green, the crop can be severely damaged by excessive wildlife (deer) both by consumption and hoof damage.  No snow cover in winter is bad and snow too long in the spring can cause damage.  Winter temperatures can reach minus 35 degrees Fahrenheit here and snow cover protects the wheat.

The wheat comes out of winter and starts growing when soil temperatures reach a consistent 40 degrees.
