When we started out in the Discovery Bay studies we installed a weather station. We started in fall of '76, which was a big drought. Drought broke in March of '77. For the next couple of years we had a minimum of one inch of rain every month into, I think, the late summer of '79. They stopped collecting that data after I left, but such ling-term data on rain, flows, temperatures, and such is critical to our understanding of what the resources are doing.
