The powerful March storms that drenched Hawaii produced more than 2 trillion gallons of rain and pushed precipitation levels to as much as 3,000% above normal in a 14-day period for this time of year.

Hoppers, like Pixar's pre-Disney films, is a delight. The beavers' world is immersive and richly realized, grounded in science but never dry. The plot zigs and zags between moments of absurdity and emotional heft to stirring effect; I cried multiple times, and not just because of the low-hanging fruit of grandma death.

After 55 days of construction, which involved enough gravel to cover four football fields and enough fuel to power a dozen homes for a whole year, the pipe is once again funneling sewage from Fairfax and Loudoun Counties to the Blue Plains Advanced Water Treatment Plant in Southwest DC.

Peat bogs provide huge value to humans and the environment. When healthy, they store twice as much carbon as all the world's forests, reducing global emissions.

Every year, American golfers lose an estimated 300 million golf balls, according to research by the Danish Golf Union - and that figure, dating to 2009, is almost certainly too low.

The largest share, $235 million, will be used to rehabilitate the Delta-Mendota Canal, which carries water to farmlands. An additional $200 million will help continue repairs on the Friant-Kern Canal, another key conduit for water in the valley. Sinking ground, an effect of heavy groundwater pumping, has damaged segments of the Friant-Kern Canal and reduced its capacity.

Signs of ageing accelerated when fish were exposed to the chemicals, according to the study, which could have implications for other organisms. Chemical safety regulations tend to focus on short-term exposure to high doses of pesticides and other chemicals, but the study focused on long-term exposure. Low doses of pesticides are widespread in the environment, so their effects should be studied and understood, the authors said.

A Reg reader received an automated call warning of potential water discoloration during planned works from January 19-25. The message advised running taps for twenty minutes if the water appeared discolored - standard stuff, if a bit robotic. In the recording forwarded to us, a female voice told our reader what to expect. All good, if a little robotic. However, things went off the rails a bit when the robot attempted to read out the URL for Severn Trent: http://www.stwater.co.uk/discolouration.

Over time, the water evaporated to form the smaller, brinier Owens Lake. Indigenous Paiute people call the Owens Valley Payahuunadü, 'the land of the flowing water'. Today, Owens Lake is a 'Dusty Vestige of the Old West', as NASA described a photograph of the lake taken from space.

Every time a boat passes through a canal lock, thousands of litres of water are released and must be replaced, usually from other sources. To reduce water loss, engineers sometimes build side ponds next to canals with several locks in succession. These side ponds allowed water to be "put aside" rather than lost. When a lock chamber was emptied to lower a boat to the next level, paddles were opened to divert the water into an adjacent side pond.

Approximately 243 million gallons of wastewater has overflowed from the pipe that collapsed on January 19 in Montgomery County, Md., according to a release from DC Water. That translates into 368 Olympic-sized swimming pools worth of sewage. The brunt of this surge happened in the first five days, before interim bypass pumping was activated a system that reroutes sewage around the damaged section.

They're special on a world stage, 85% of chalk streams are in England. They're wonderful habitats, they're great for people as well, people really enjoy them, whether it's areas like this where you can find kingfishers and grey wagtails and it's just a unique resource that we really should steward properly.

The government said the plans would increase the number of England's official bathing sites to 464. An official bathing spot on the Thames in London would mark a "vast transformation" in water quality in the river which was declared biologically dead in the 1950s due to pollution, officials said. Water minister Emma Hardy said rivers and beaches were "at the heart of so many communities, where people come together, families make memories and swimmers of all ages feel the benefits of being outdoors safely".

The proposed 1.5 million acre-foot Sites Reservoir would store water from the Sacramento River and distribute it during droughts to several parts of California, including the Sacramento and San Joaquin valleys, Southern California and the Bay Area. Stretching about 4 miles across and 13 miles north to south, it's meant to provide water to approximately 24 million people, and it would mark California's first major reservoir project since 1979, when New Melones Lake was completed.

The surge of water, more than 22,400 gallons a second, plunged from the foot of Warm Springs Dam, launching a fine mist above. That was the spectacle of abundance last week at Lake Sonoma, the North Bay's largest reservoir, where the U.S. Army Corps was releasing what dam managers call an "oversupply" - the welcome product of heavy runoff from recent storms.

At the center of the dispute are eight dams and reservoirs on the Columbia and Snake Rivers in the Pacific north-west that have created devastating obstacles for salmon and steelhead unable to breach their deadly turbines or navigate through the large, warm, artificial pools.

Western water law is based on the prior appropriation doctrine, which gives the first entity to make "beneficial use" of water the right to keep on using that amount, even if that means that upstream "junior" users' spigots will get shut off. By the early 1900s, a rapidly growing California was enthusiastically diverting the Colorado River, with huge irrigation districts gobbling up the senior water rights.

Wildlife populations are in decline. Recreation sites are crowded and often underfunded. Wildfires are larger, more destructive and harder to control. Climate change is reshaping natural systems, from ocean fisheries to mountain snowpacks, faster than institutions can respond. At the same time, communities are being asked to host new energy projects, transmission lines and mineral development - often without clear processes, adequate resources or trust that decisions are being made in the public interest.

Data published by the insurer Aviva reveals that of the 396,602 new homes recorded by the Ordnance Survey in England between 2022 and 2024, 43,937 are in areas of medium or high risk of flooding, while 26% of new homes have some risk of flooding.

So, with this storm surge and the King tide event, it was a great opportunity for us to test this out. So, we came out here and we were able to further document and see how well it performed. So, we got to see that the king tide came up very close to where the pathway is behind you, and it did what it's supposed to do,

The question of how to protect fish and the ecological health of rivers that feed California's largest estuary is generating heated debate in a series of hearings in Sacramento, as state officials try to gain support for a plan that has been years in the making. "I am passionate that this is the pathway to recover fish," said state Natural Resources Secretary Wade Crowfoot. "This is the paradigm we need: collaborative, adaptive management versus conflict and litigation."

One veteran biologist said it was the most positive freshwater conservation story he had seen anywhere in the world in 20 years. It is really fantastic news. It is one of the first times that we can say that government measures have not just worked, but have really improved things, said Sebastien Brosse, of the University of Toulouse in France.

Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging. At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

It's a sight that usually means California is having a good winter and water supplies are healthy. This week, operators at Oroville Dam, the tallest dam in the United States, which holds back California's second-largest reservoir, opened the spillway gates and began releasing billions of gallons of water down the massive concrete spillway into the Feather River below. The reason? It's not to waste water. But to prevent potential floods.

Rep. Jared Huffman and Marin County Supervisor Mary Sackett speak to reporters during a tour of the Santa Venetia neighborhood of San Rafael, Calif., on Monday, Jan. 5, 2026. Parts of the neighborhood flooded during recent king tides. (Alan Dep/Marin Independent Journal) Ryan Davis, general manager of Fitness SF, talks to reporters about recent king tides at the sandbagged entrance to the gym in Corte Madera, Calif., on Monday, Jan. 5, 2026.

New filtration technology developed by Rice University may absorb some Pfas forever chemicals at 100 times the rate than previously possible, which could dramatically improve pollution control and speed remediations. Researchers also say they have also found a way to destroy Pfas, though both technologies face a steep challenge in being deployed on an industrial scale. A new peer-reviewed paper details a layered double hydroxide (LDH) material made from copper and
