Return to work. And to stay ahead of the pandemic, america will need an additional 100,000 contact tracers, according to Johns Hopkins university. By one count, states have hired or announced plans to hire about 66,000 so far. Does the lack of a federal standard put your state at risk and surrounding states at risk . I certainly think if the feds were to participate, if the feds were to establish, as you say, National Standards or some rules around compatibility with respect to one state to another because youre right, there is a lot of back and forth between states. And people move. They dont just work, they move. I think that could be very helpful. Reporter as more americans test positive for the virus, researchers say confidentiality is key for contact tracing. That means shielding the identity of every covidpositive patient. Even from the people they may have infected. Contact tracing is critical. Virtually nobody disagrees with that. But out there in the public, there is a concern that the more that the government even if its the Health Department is prying into peoples lives and movements, the less privacy well have as americans. How do you balance the Public Health mission with the privacy concerns of citizens . I would say we take confidentiality very seriously. Thats a big component of what we do as far as not sharing information of who is a positive test result. That is extremely important. But also by notifying people that they may have been exposed, it greatly reduces the spread of the disease. So the more information people can provide, the better and the more effective that this technique will be. Later this month google and amazon will release a tracing app for your phone. Its supposed to send you an alert if your phone is too close to another phone that may have been near another phone of someone with the virus. Well keep you posted on that.

All that heavy snow this winter in the rockies and Sierra Nevada should be melting now and filling the vast reservoirs of the American West. Instead the reservoirs remain at dangerously low levels. And as John Blackstone reports, its a problem thats been building for years. Reporter springtime is when reservoirs across the American West should be full. This year, as in many years past, they are not. Lake powell, the Colorado River, big white bathtub rings around them, left as the water declines. There is less water in the system now than there was 20 and 30 years ago. Reporter john flack, author of water is for fighting over has spent decades studying the Colorado River, a crucial source of water in much of the west. The persistence of the Drought Conditions in the Colorado River basin especially is essentially unprecedented in human history. Reporter what is happening, a new study says, is not just a drought. Its a megadrought. Its a pretty dramatic term, megadrought. If you go back in time 500 years or so, there were these phenomenal droughts in terms of both severity and in terms of length. Until recently those droughts have always been spoken about with almost a mythicaltype character. Reporter park williams is lead scientist on research that uses tree ring evidence going back 1200 years to study megadroughts that lasts as long as 40 years. And the drought of the last 20 years has developed the same way the megadroughts did. Reporter there is, however, one difference between this long drought and the megadroughts centuries ago. What were seeing today is a combination of natural Climate Variability as well as human cause Climate Change. We would have a drought even without Climate Change, Climate Change is making it a whole lot worse . Without human cause, Climate Change wed still are a drought but it wouldnt be as serious as the one weve actually seen. Reporter 75 of the wests water supply begins as snow. When you get a big snow pac, you hope it will fill up your reservoirs. With Climate Change it doesnt fill them up as much as it would have without the warmer temperatures. Reporter in the mountains above boise, idaho, scientist Peter Marshall is developing better ways to determine how much water there is in the snow pac. Its becoming more challenging for us to not only predict how much water is going to enter our reservoirs, but also the ability to store that water all the way through the end of the summer for agriculture and water resource purposes. Reporter marshall is part of a nasa project called snow x, developing Remote Sensing equipment to get accurate snow pac measurements from space. So one of the big pushes for us to develop a spaceborne approach to monday torning snow Water Resources is because these patterns are changing. So were really needing a approach that maps the amount of water thats stored within the snow pac. Over the past couple of decades, weve had a few years of drought, and then we sometimes have record snow, record rain flooding. It looks like the drought is over. The thing thats changing now is that when we do have those wet years, when we do get a good snow pack up in the mountains over the winter, were seeing less water make it into the rivers and downstream to the farms and the cities and the fish and the eco systems that depend on that water. Reporter planning water use will become even more crucial if, indeed, the west is in the midst of a megadrought that this morning were remembering the life and music of the legendary performer Little Richard. He died this weekend after a long battle with bone cancer. Little richard was 87. Anthony mason has this tribute.
