EnidBuzz has the annual feature on THE FLOOD, 10/10/73. The commenters hit the story from different sides as you’d expect. Here’s one I hadn’t heard before:
I lived at Altus at the time & heard that the farmers near that area had the clouds “seeded”. The resulting rains moved up to the Enid area instead.
Earlier I was wondering why cloud-seeding was abandoned. Clearly it wasn’t abandoned because it fails. There’s plenty of solid evidence that it works, often but not always.
This direction of failure makes more sense. Seeding can produce vastly more rain than Nature intended.
