Good news on the spills...
I've read that ensuring such flows has been directly and measurably linked to successful passage of PNW salmon. In fact if I am not mistaken very few of the efforts made (e.g. barging) have made a difference where this has always had a positive influence.
Most of the time this was due to overabundance of water, not proactive thinking. But I am glad someone was paying attention during high water years, now we know how important it is to regulate flow for fish, not for human needs alone.
