@ rocdoc......I suspect you could be correct......I hope you are wrong.....but recent events certainly make me doubt the average intelligence of our species

it seems we are perhaps most highly motivated by the effect on our wallet

It will take a lot more rain to end it. One of the better tools to monitor the conditions is the water levels in the reservoirs.

pstarr wrote:vt, I introduced the club to cdec, and I know how to use it. You need to look to historical data to understand reservoir levels. Here is a link cdec storage at Shasta

The current chart shows an exceedingly rainy Oct/November, and reservoirs that have remained relatively full from the previous abundant rain year. In fact only two previous years since 2007 exceeded this early high storage level.

vt, your chart compares current storage to an entire historical storage year. Of course the reservoirs are not full now. The rain year just started. We are just coming off the very end of the the previous seasons dry period. When levels are always low. But the levels in the chart you posted are actually incredibly high . . . for the date.

I might be mistaken but I am under the impression that the orange line average level changes with the day of the year. Near full in spring and much lower at the end of September after the end of the summer irrigation season.

pstarr wrote:You are correct vt, its says on the key for the chart: "Red Line: Historic level for date." Could be early releases for fall salmon runs?

Last winter Shasta got as full as they let it get (flood reserve space) but none of the others made it to full and many in the south stayed well below normal. They have a good start this fall and April one might look better then it has for several years. Here is hoping!

Water rationing introduced as Bolivia drought worsens
Water rationing becomes permanent in La Paz as the dams run dry.
