[18] Twenty-nine agencies hold contracts for SWP water. The contractors pay for SWP's major operating costs ...
This can cause decreased water quality and lead to an expensive desalination effort to clean the water before distribution. Water flows through wildlife refuges and national parks can decrease or stop all together due to the decrease of surface and groundwater, the California Water Science Center is a part of a team trying to restore and ...
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total.

Seventeen people have died in a series of atmospheric rivers that have slammed into California in the last two weeks. Rains blamed for 17 deaths in California, a state primed for very different ...
On Jan. 30, the water content was just 52% of the average for that date — a far cry from a year earlier when it was around 200% of its average content, thanks to repeated atmospheric rivers that ...
Our World in Data uses interactive charts and maps to illustrate research findings, often taking a long-term view to show how global living conditions have changed over time. Compilation of graphs from the organization, showing the overall global percentages of the last two centuries, in six factors: extreme poverty, democracy, basic education ...
