Lake Mead is a reservoir that helps supply water for 25 million people in Nevada, Arizona, and California, and some in Mexico. The dam that created the lake is the Hoover Dam, built in 1936.
It is one of a series of dams in the West of the USA that store water and generate electricity enabling cities like Los Angeles, Las Vegas, and Phoenix to exist in the desert. The water enables farming as well as supporting habitation.
Increasing population, rising demand and years of drought mean that the reservoirs are running low. Dean Farr’s data and interactive map illustrate the issue beautifully. The challenges and implications get excellent coverage in Vox.Read more

Flash, I love you! But we only have 12 years to save the Earth!
In the film of Flash Gordon, NASA scientists claim the unexpected eclipse and strange hot hail are nothing to worry about.
Not so in our current reality. The most recent Intergovernmental Panel on Climate Change (IPCC) report has warned that we only have 12 years for global warming to be kept to a maximum of 1.5C, after which even half a degree will significantly worsen the risks of drought, floods, extreme heat and poverty for hundreds of millions of people.Read more
The UK Climate Projections 2018 study says that summer temperatures could be 5.4C hotter by 2070.
The chances of having a summer as warm as this year’s summer (2018) is currently 15-20%. That’s going to rise to 50%. In other words, as likely as not.
The warmer summers will also be much drier, with average summer rainfall dropping by 47%.Read more

Water companies face many challenges. Increasing and urbanising population, more extreme weather events, ageing network infrastructure, an ageing workforce, and customers becoming more demanding. The problem is they don’t have more money to address these challenges.Read more
