. >> brad colorado. i was not planning on speaking. i just wanted to mention to those of you who have been to providence the haven brothers diner in front of city hall. i do not think it is 36 feet long, because it has to be towed. every time i go back, i have a cheeseburger and a piece of pie. it is open from 8:00 at night until 4:00 in the morning. it creates real activity around city hall when it would otherwise be dead. the food is really good. i would take this gentleman's comments to heart and see if there is a way we could encourage more diverse kinds of mobile food like the haven brothers in providence. thank you. president miguel: thank you. is there additional public comment on this item? if not, public comment is closed. i was excited to see this item come in front of us. i am a fan and user of mobile food trucks. mr. sider, i have a couple of questions to clarify two items. there is not a truck but a trailer, if my memory is correct, parked in a parking lot at second and howard that serves crepes. it is there. it is a comme

brad said the colorado river and it's use of,hydrology, and it occurred to me, why are they not addressing climate change. why is the bureau not integrating it into the analysis of the system and i'll come back to an example of that in a moment. we have not yet done in california a systematic assessment of reservoirs. there have been some studies on specific reservoirs or river basins and how flexible or inflexible they might be under existing rules and there are a couple of studies that look at different kinds of reservoir rules but not systematically and i don't think there's been any system reoperation. corner me later and tell me i'm wrong but i would argue that on the demand for water. it has been mentioned a coupl of times here. seattle may have done that and port land may have integrated it into management. temperature is going up, demand for water is going up. how many of our water agencies include in their demand forecast for the year 3020, 3050, climate effects on demand. the last california water plant did a much better job of acknowledging the issue of climate change but not ye

brad? [applause] >> good afternoon, dan i'm from nebraska actually. actually, i'm not but colorado is close enough and will have to do in my point. those of us from other parts of the country are looking very carefully to what your doing here and we're learning a lot of great lessons and we hope the sea level rising is a lesson we don't have to learn but you all, are doing fascinating work. i road in last night with joel smith and he said with a wink and nunl, never turn down a trip to san francisco or new orleans. we have one still left. all right. i'm going to talk about a shared resource in the west and my first thing here is all important dividing line on the upper and lower basin colorado line. this photograph was taken lo 1880's and you will see the lower right, the founder. john lee is actually my grant grant grand father. you might think it's remarkable to be a descendant of the guy, but he had 21 lives and by my count about 2500 descendants right about now. let's go to the next. you probably all know the overview of the river. those that never heard of the colorado river l

brad mentioned about trying calculate the environmental water demand. that is how much of our water that's delivered is lost to eva evaporation or transportation, the residual is the run off you get in the colorado river or some other river system. that's very much under debate in the scientific community right now. its the first order of question. a few percent have a very very large impact, so this that's one of those things that there are a lot of studies going on and i think is a scientific issue, which probably will get more refined and we'll get better at that one. that's where i stop. thanks. [applause] >> afternoon. i'm barry nelson with the water project here in san francisco. i'd like to start by thanking the city for pulling this conference together and note it's in some way as real landmark event. this is, i think the first conference i've attended with water manager's. this is the first one where a significant portion of the event is not devoted to whether climate change is real. i think water managers really in the last couple of years have moved past that and now we're ready for the next step in that discussion, what are the impacts of that and what can water managers do to adopt
