you probably all know the overview of the river. those that never heard of the colorado river let me give you facts. 7 states and two nations share it. the fastest growing part of the nation by percentage or numbers. including utah, arizona, and nevada and california just on sheer numbers. 8 percent of the land area in the united states and it has 60 million acre feet of storage and that's closest to the highest in the world relative to it's annual flow of 15 million acre flow a year. it's about five to 25 million acre feet. there are 35 million people served in an enormously complicated legal environment. what happens after 7 years of drought on the river. these are two parts that have 50 million of the river in storage and we started out with full reservoirs and you end up with these enormous drops and we're at about 50 percent of the average. underaverage lake immediate will never refill given demands on the system and lake paul will take decades. it estimated ten acre feet per year and that's a serious history record, there's no

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 their operations appropriately. th

in this river are fish. we will take the right hand over our left and use our thumbs like fish fins and let your fish swim through the water it takes a big dive. >> and growing next to the river are a bed of flowers. opening one hand onfinger at a time watching the flower petal blossoms. we will take our other hand and turn it into a butterifiy much the butter fly will fly, fly, fly the and land on the flour and watch it fly away. drinking can a deer. take your thumb and the outside a n antlers. the deer hears a noise and in the distance is a hunter with a low and arrow. he sees that deer and aims for it. see your target and takes a shot and he misses and the deer escapes. the hunter's frustrated. i can't believe i missed that. he decides that hunting deer is not a night idea next time he will aim for an apple. thank you participating, you can sit down. give yourself a clap. those are very basic hand movements we use to tell a story. so, the next story we will show you is going to take place in this forest t

kharaghani: the los angeles river is approximately 51 miles. concrete reduces the size of the river that you need to carry the water because it speeds up the flow of water. if you'd like to remove all the concrete and to have natural system to carry the water to protect you from flooding, you need to have almost one mile on each side of the river set aside for transport of rain. so in order for the city to have use of those lands around the river, concrete made it possible to have minimum land so the water can be carried to the ocean in the fastest possible way. but, unfortunately, because of population growth and poor housekeeping, people are putting a lot of pollutants on the street and the streets are the openings to our stormwater sewer system. in an average year, 4,000 to 5,000 tons of trash ends up in long beach. man: we've created a system to deal with flooding but inadvertently created a pathway for pollution to get into our waterways. narrator: los angeles county is beginning to develop ways to reduce the infrastructure's impact upon t

we were there at the moment on river road. residents from about 200 homes along the san lower yenzo river were asked to move out to relocate. the reason, of course, because the river crested. it was coming down rather hard around here. the river right below the covered bridge was full of debris, logs and that created a mini jam. at 3:25, reverse 911 system was activated. felton firefighters went knocking on doors and asked them to evacuate. of course, few did. those areas of -- . >> right now we're just warning people the river at warning level. we're going door to door letting them know it can flood. >> and okay. so those areas affected felton grove and gold gulch. 825 people were affected. evacuations did not last very long. the main reason is because the river, the water started to recede, the rain has subsided quite a bit. waits raining again before and there is a lot of debris, a lot of the logs they've managed to clear them out. i'm live near felton abc 7 news. >> thank you very much. there is a massive tree came crashin

so their search led them to the nearby schuylkill river. philadelphia developed technologies to pump water from the river into the city. these technologies established engineering concepts that are still the basis for our water systems today. europeans flocked here. it was a destination point to see the new world technology. when charles dickens visited us in 1840, he was truly blown away by high water pressure on the fourth floor of the hotel he was staying in. nowhere in europe had he experienced that. this technology was doing something to support the life and the growth of the city. philadelphia, throughout the 19th century, was the major industrial city of the united states. all of these industries used water from this system. and it served as a prototype for many american cities, including pittsburgh and new york. man: new york city went to philadelphia and said, "you know, we're thinking of developing a hudson river water supply -- what do you suggest we do?" and they said, "we've had "a lot of problems on the schuylkill. "don't go t

it's a river running down the road. >> reporter: and of course it's the river here, the san lorenzo river that has everybody concerned. about 700 people who live alongside the river have evacuated. they've been told by county office of emergency services to leave their homes with the reverse 911 call. it's a precautionary measure. at this point, they're going to keep people away from their homes, again as you heard earlier the flash flood warning has been extended until 6:00. we'll keep our eye out on this river and the people who live around it and give you an update at 6:00. robert handa, ktvu channel 2 news. >>> now to the east bay where it's taken drivers an hour and a half just to drive from fremont to oakland because of emergency lane closures due to all the rain. john sasaki is live with more on that and other serious problems from this storm, john. >> reporter: today's downpour has been wreaking havoc. two ahead and take a look at the left lanes. crews are filling potholes, closed down two lanes. the right two lanes as you're going northbound. looking at our 880 cam you can see tr

system in this case the american river in a given year. here's when,folsome damage was built. these are the flows when they did not have the operations for flood management that's how you would study the reservoir. now look since it was built. six of the highe flows recorded have happened since the damage was built. has the corporation changed the criteria, no. we have been aware of this from some time. 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 p

the river ran over the banks around 3:00 yesterday afternoon. when the water reached just below flood stage at 17 feet, sirens went off to alert people to evacuate. but by dinner time, the water did start to recede. people living along the river say they are prepared with sandbags in case the water starts to rise again. and some owners have raised their homes. >> originally, these houses were down low. like this house believe it or not was one story. and then i guess they came in and said, since you live so close to the river, you have to jack them all up. just because of the water. >> and evacuation area is set up at the safeway parking lot, but few people showed up. >>> more flooding concerns this morning, this time in the north bay where the napa river reached 22 feet yesterday putting the river at monitor stage. people who live along the river say they know how dangerous the water can get. ten years ago, heavy rain and flooding forced them from their homes. >> i remember the streets flooding and houses under water. and everything. >> reporte

and so for the past decade, the city has embarked on a program to clean up the river. now, with 1,800 miles of sewer system, three sewage plants and combined sewer overflows, it took a number of years to figure out what would be the solution. we are facing a crisis in infrastructure. bethea: a huge change came about when mayor shirley franklin became the mayor of atlanta. we're having to choose how to spend our money. i named myself "the sewer mayor," and i wear that title very proudly, because, without wastewater infrastructure and drinking water infrastructure, the economy will stop. we did a major outreach. we trained an outreach team, who went to every community meeting, to educate people on how bad the crisis was. not only did i tell people that we'd have to raise rates, i told them we'd have to tear up the city to repair this infrastructure. man: you can't simply say, "i won't use any water, it's too expensive." we have about 25% of our population that's at or below the poverty line, so you have to look at rate structures that are tiered so the people can pay the

the river is currently at flood stage. now, in terms of the north bay, the worst weather has mauved to the south, so you're getting much needed drying right now. for most of you. however, in the east bay, we still continue with very slow moving moderate rainfall. and even some pockets of heavier rainfall in the south bay. we'll talk about another storm coming our way and really the wind impacts could be the largest thing with so many power lines and trees already weak. s >> thank you, jeff. earlier we told you about a river rescue, so be careful near any of these bodies of water. we want to bring in elyse now. >> people are just 14ri7 ship sliding all over the place. >> reporter: chp tells me on a typical day they respond to about 10 accidents. today they saw about 60 and all were weather related. 40-miles-per-hour wind gusts whipping around boats and on local bridges, cars getting pushed around. to rain drenches city streets and local roadways. >> pretty slow. >> reporter: motorists are forced to slow down, yet another ma

this is the jubilee river. it is basically a duplication of the river thames. we are likely to see more conveyance solutions of this type being constructed in the future. many of you will be familiar with the thames garage project. this has been in operation for quite a number of years and essentially protects the whole of the essential london area from rising sea levels. this will have to be replaced with a much bigger barrier in the future and starts have already been made on planning and estimating costs. it will be totally impossible to defend all coastal areas from sea level rise in the future. it is only the high value areas where we will be able to afford such protection from coastal changes. in our urban areas as well, as i said, we will not be able to afford simply to increase the size of our infrastructure to deal with the increased storm events we will see as a result of climate change. this is a picture of severe flooding in glasgo, scotland in 2002. you can see the contribution that the drainage system is making here. you can see the water streamin

in early spring people use the river to get to the rocky range where a cave. is situated along a tributary of the larger river nature reserve staff only learned about its existence by chance. when you're not here we had not been aware of its existence for ten years when locals told us about it they said she played once in shelters in the caves first tunnel when we first came here we did see tracks left by sheep yes that's right i remember the first time i came here we did see tracks left by sheep . the cave extends for more than a kilometer several narrow corridors hide a large central chamber the cave walls are covered in drip stones still are tights and still like markets. in the north caucasus largest that rockery hibernates deep underneath the ground they represent the red book species the male seared bat and the horseshoe nosed. more than two thousand bats gather here in the winter a couple together in order to survive the cold weather in summer they fly to the foothills and return again in autumn they start preparing for migration in early spring when th

draw down the river 25 feet and see if our models are right. there's a lot of things we can do with models without physically doing it. there's compelling scientific evidence that posted challenges to our water systems. unfortunately, there's pretty serious evidence that we may not about quickly or effectively enough to prevent some pretty extensive consequences for us. i think that's a problem. . manager's must use current tools but also look at future risks. policy manager's have the opportunity to do this. we already manager for variability and risk. we build homes in earthquake zones not knowing how big or when the earthquake will be. but we manager risks and we have lots of tools for doing that management but we're not doing enough yet. either in planning or actually on the ground action. we do need to take more on the ground action. ultimately the impact will depend on our ability to for see major changes and do the analysis and adopt and implement changes and this is in the face of surprises, because as much as we know, there will be sur

the tsunami backwashed up the river. tsunami experts came to this town to investigate what had happened. they expected places where debris had been washed ashore, and they found that a tsunami had hit an area four meters up the motor of the river, and that tsunami maintained its momentum and flow up the river 8 kilometers upstream carrying debris and causing damage. how did the tsunami come this far? experts say that a 10-meter tsunami rushed up a river that was flowing in a straight line and did not lose momentum as it climbed up the mountain. they point out that tsunami measures are required at inlet areas also. >> in a tsunami this large it's very difficult to prevent damage, and even in the inland areas the tsunami will attack. therefore, people npt inland areas also have to plan evacuation routes and be prepared for such disaster. >> and now we take a look at lathe latest in business news. >> welcome to "newsline business." japan has asked trade partners not to impose any unfair import bans on farm produce due to ra

these three rivers are vital for industry, recreation, and drinking water. and each year, billions of gallons of combined sewer overflows discharge directly into those rivers. hecht: we're now having to face the consequences of the choice that was made to put in combined sewer systems. narrator: in 1994, the government adopted a combined sewer overflow policy to reduce csos nationwide. cities with combined sewer overflows now face an enforcement action called a consent decree. under a consent decree, a city must reduce pollution levels significantly within a strict time frame or face heavy fines. in 1960, the combined sewer overflows were a perfectly legitimate way of dealing with sewers. woman: the mind set was that, what did it matter if we were sending our waste downstream? water was a good conveyance for pollution. man: sewer systems are installed to reduce public health problems. now what you're doing is transferring the problem, you're transferring it to downstream cities. in addition, cities and towns above pittsburgh were doing the same thing. and th

rushing water also turning roads into rivers. you can see the river of water on graham hill road in sonoma county. a man is lucky to be alive there in morning after the roof of his monte rio home stopped a giant tree from landing on his head. the man went out to investigate just as the tree came down. also in sonoma county a tree took out an entire neighborhood's power supply when it landed on power lines. >>> in san jose a rush hour rescue on 87. a driver spotted a man in the fast-moving guadeloupe river. he saw the man clinging to a tree in the river, called for help and rescue crews searched the frigid water. they found the man even further down the river. the victim had been in the water for more than three hours by the time he was boated back to safety. no word on how he ended up in the river, but it is a reminder how fast and cold the local waterways are during the storm. stay away. >>> the man who confessed to killing chauncey bailey will be back on the stand monday. the man is testifying for the prosecution against two ot

not a river, two rivers run right through his front yard, into his driveway and dangerously close to his garage. >> i keep them dry with the panels. >> reporter: so what do you do? >> well, these panels are basically waterproof. they're metal, they come up and they bolt up against the wall. and then, as the water rises, i can put a second panel on and a third panel and i can literally get it right up to the top and seal the door off entirely. >> reporter: northern new jersey has already had one and a half times more rain than it would normally have from february until now. this river is expected to crest early in the morning and a few hours later, more rain. diane? >> all right, linsey davis. this is a huge part of the country facing this. a country already watching gas prices rocket into the stratosphere. and today, the department of energy gave an official warning. americans will be paying on average $3.70 a gallon by spring. and by summer, possibly over $4 a gallon. but we wondered about all the gas stations we hear about around the country, already charging those sky-high prices.

this is mississippi river, the actual flow at saint louis. the data comes from the armed corporation to around the year 2000, to 2001. if you draw a straight line here, the straight red line is basically the flood risk, assume this record is stationary that the climate is not changing. in fact, statistically, if you ⌜"at this record, it's not stationary. average flow in the mississippi river seems to be going on. i don't know if it's climate change but its the kind of thing that makes long-term planning managers nervous. one is the model you plan for the average flood over the last historical record or potentially the tree ring record or whether you assume climate is not stationary and in which case, the model of what you do and the assumptions, and the conclusions of what you do will all be different. so what has been done? well, i don't think a whole lot. a lot of the thinking and a lot of things have been done in modeling and planning but in terms of on ground action, not much is done. i know city of san francisco is re-evaluating storm wa
