Riding the Wind 1942

It's the ranchers whose cattle are dying of thirst versus Henry Dodge whose dam holds all the water. When windmills are built and they start pumping water, Dodge has them blown up. When a court order forces him to release the water, he decides to blow up the dam and flood the valley.
