That is a design you would expect to undermine the emergency spillway if you ever had to use it, and a long use would end up dumping 30-odd feet of retention lake catastrophically when the emergency spillway finally failed.<br /><br />If they had included a concrete pan out 30-40 feet we would be focusing on the major failure on the regular spillwayRick Thttps://www.blogger.com/profile/04748076795783834112noreply@blogger.comtag:blogger.com,1999:blog-4533651942397782565.post-59282034056096611462017-02-17T13:49:33.079-08:002017-02-17T13:49:33.079-08:00As a note about the Fulsom dam and reservoir, in t...As a note about the Fulsom dam and reservoir, in the 80s the greens sued the Corps of Engineers to stop dredging the reservoir, so now decades later it holds a significantly smaller amount of water than it could.<br /><br />Also, SMUD, wanted to build a series of dams north east of Placervulle in steep, narrow valleys where no one could build cabins or live but was shut out by the greens. CW may remember that battle because he lives nearby.<br /><br />In typical Californian insanity, along Highway 50 east of Sacramento, developers built a dry subdivision because there wasn't enough ground water to support the subdivision. Everyone agreed it was going to be dry, but now three decades later the courts ordered that subdivision onto city water because the residents were tired of purchasing and hauling their own water as originally agreed upon.<br /><br />DaveAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-4533651942397782565.post-21430820876688613712017-02-17T13:42:00.146-08:002017-02-17T13:42:00.146-08:00Thanks.

The higher the head, the more energy created by the fall of the water, and the easier it is to generate more electricity. Hence, the best location is at the base. <br />Second, there is the chance of water backing up into the powerhouse, but the people who design these big dams like to think that they have considered all the scenarios where that can happen, and design that possibility away. It would take an extraordinary combination of events, so strange to the logical minds of the architects and water managers, to cause a significant water backup into the powerhouse, that it is just about impossible. Looks like the situation at Oroville Dam is going to prove that it is in fact possible with the right combination of sudden natural events and human incompetence stretching over decades.c w swansonhttps://www.blogger.com/profile/02735507642689652780noreply@blogger.comtag:blogger.com,1999:blog-4533651942397782565.post-53976971974135279522017-02-17T11:44:32.903-08:002017-02-17T11:44:32.903-08:00Why is the powerhouse at the base of the dam where...Why is the powerhouse at the base of the dam where it could be flooded?
