outflow 5300..looks like they got a 3rd turbine going

so far it looks like 1700 cfs per turbine
5 turbines(a 6th is down for repair) so 8500 max?

I seem to recall that they were able to run up to 2300 or so on a single unit the other day. I think they might have 3 running but at less than full output, maybe in a cautious approach. They can vary the output by adjusting the wicket gates (more or less, valves where the water enters the turbine). Normally, we use them on our hydro generation plants to regulate the power output of the generator, but the side effect is that it also controls the amount of water passing through the generator's turbine.

But I'm seeing the same thing - 1700-1750 per unit at the present level of generation.

Information on the Hyatt Powerplant located in the Oroville Dam.....

According to the chart, 3 generators are able to pass 2800 cfs at full output, and the other 3 2850 cfs. So they are definitely not running them at full capacity.

I think they want to see the effects of each additional unit on river flows. They seem to be starting them in the evening and letting them run overnight before making a morning assessment.
