this is feather river and,orville, was constructed here and if youed a 06 you would have four of the highest flows that have occurred since we constructed that. from a flood stand point we're not taking this into consideration. in terms of the roll or rule terms there's not much change in those. final example is san,jaoquin, refr, you see 2006 is missing. there's a couple of points. one, the flashier nature that will continue as we lose snow back. the other is from a flood standpoint, but if you think about the hundred year flood has a chance of occurring one in a hundred years. most of that analysis was done in the first or middle of the past century. all the higher flows have occurred since then some what is the real hundred year event now and what is it going to be. so how do you design your flood systems to deal with that and they may be robust and not just rely on flooding levies. next slide. again, kind of a summary. much higher inflows during winter and early spring we have to maintain greater flood control space and if all you do is that you probably lose greater water supply
