There is a lot of irrigation in the area for hay crops, that is beef cattle country. If a pipe had been leaking for some time the water may have been backed up then burst through a natural dam. We have had quite a time with road washouts here in B.C.
There are vary few irrigation systems that will provide that much water.
Unless there is a irrigation canal in the area above the wash out I really don't believe it was an irrigation system that caused this, simply because of the amount of water it would have taken to do this.
Nearly identical incident occurred on Highway 20 in Washington state. simply heavy spring runoff, pluged a culvert, and overflowed the road taking 350 yards of road bed with it.
