increase demands in the summer with reduced supplies. so, in terms of climate change impacts portland is most concerned about. here are five according to me and my staff. i m sure there s more and thinking on this i tried focus on things we re dealing with now. as i mentioned the higher summertime demand because of higher temperatures. this would be by growth alone and that s a significant issue. the other side of the coin with that is having less supply during the summer and if we re in a situation where we have a longer drought period we like seattle have annual refills with reservoirs and a summer draw down where we re serving from our reservoirs if that presents challenges for us. increase in wild fires. it s a huge concern for us and i m sure for like san francisco we re an unfiltered drinking source and our watershed is in the mountains where there s lots of reck rauks and eventhough it s protected and there s no entry allowed our watershed we re are neighbors of an int
supplies and water recycling the fact is they have been operating in a water supply deficit. thankfully for that period we ve almost always had above average rain fall. if that occurred today, those residents despite all their plumbing facilities and other efficiency measures would have to reduce demand an additional 70 percent in order to keep from running out of water. the choices faces, them like many in the west are not easy and certainly not cheap. you re going to find a common thread the area of cheap and easy solutions to water supply is over. consider the fact that,mufd, is sponsoring around 8 hundred dollars an acre foot if any of you are paying more than that for incentive programs i would love to know but that probably is setg the pace. the district is considering a plant on san francisco bay to diversify it s water supply, portfolio and supervise a hedge on patterns that are likely to get even more volatile with climate change. yes, it s expensive but how do you v

good morning., i m edward campbell and planning deck tore for portland oregon and i m here on behalf of our water bureau who sends his regrets. i m very glad to be here today before i start on the story of portland i want to say the morning session has painteded a picture for me of the scale of issues you face here in california and i hope the story i tell you about portland which we are a drinking water only utility and 80 miles away from the pacific ocean that there are lessons that can be useful to you but our issues pale in comparison to the issues your dealing with here. first a quick description of our system. its the largest one in oregon serving about 8 hundred thousand people. 25 percent of the state and average a hundred million gallons of water a day. our primary source is the bowling river in the cascade mountains east of the city and two reservoirs and ten million gallons of usable storage. we have a secondary ground storing source on the south side of the colo
our system. its the largest one in oregon serving about 8 hundred thousand people. 25 percent of the state and average a hundred million gallons of water a day. our primary source is the bowling river in the cascade mountains east of the city and two reservoirs and ten million gallons of usable storage. we have a secondary ground storing source on the south side of the colombia river and we have capacity to serve our base needs just by ground water some you can count portland among those that believe climate change is real and have been following it for over two decades. the ctional is a national leader. i know i need to tread carefully in san francisco talking about treading in this area but most of you are probably familiar with the list i have up here on this slide. in terms of predicted impacts for continued global warming on western water utilities perhaps it is most fundamental. what we re really struggling with is the notion we may faced increase demands in the summer
