I am a dam operator on the lower Colorado River. In fact the last control structure on the river, the Imperial Dam. While we are not a storage dam in the sense of Hoover or Glenn Canyon (we are a diversion dam), we play a vital role in the delivery of water to Southern California and Arizona. A strong El Nino will have a HUGE impact on our scheduled deliveries. Weather in general plays a big part in over-runs and shortages on the river. Every cubic foot of released water has a destination, farming mostly but cities and municipalities too. Extra dry or extra wet weather as you can see is very important for us to know. So glad I found your informative, easy to read site! You are book marked and will be back often, Thanks!
