I was at a field station in Discovery Bay and one of the the things I was monitoring was rainfall and streamflow. When we started (late '76) it was a drought. That broke in May of 77 and we had at least 1" of rain (in a rain shadow) for a couple of years. After I left, the data collection ended. Would be nice to see what 50 years of data looked like and what changes occurred. Probably look at the fall flows as they affected summer chum coming upstream.

Also looked at flows on the Cedar with sockeye. Back when we had the first crash. I was looking at rainfall in the Fall. I think September-December, which was spawn time. The total rainfall was the same but the distribution changed. I can't remember the details but an early month got drier and a later month wetter. It looked like the fish that spawned earliest spawned in the thalweg, as that is where the water was. Much higher flows later would scour this out.

It would be interesting to see how the "creek fish" deal with low flows in early spawn and if this shifts spawn time and entry time; making them later returning.

Really long data sets are good things to have and I suspect 50 years is not really "long".
