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.

Most water filter pitchers are made of BPA-free plastic. But as new research shows that bottled-water drinkers ingest tens of thousands of excess microplastic particles, wellness lovers have begun to look askance at water filters that are themselves made of plastic.

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.

In many Texas households, outdoor watering accounts for more than half of the total summer water use. The biggest mistake people make is watering in the middle of the afternoon. When the sun is at its peak, a significant percentage of that water evaporates before it ever hits the roots of your St. Augustine or Bermuda grass.

The Colorado River is an interconnected system, sustained by Rocky Mountain snowpack, rainfall and groundwater. It is fragile, and under increasing stress. Two and a half decades into this century, the river that built the modern West has 20% less water flowing through it than it did on average in the last century. As heat and drought intensify, so do the stakes: Failure to recognize the severity of changing conditions, managing the river in parts without considering needs of the whole and inadequate planning for long-term shortages put the future of all the basin at risk.

Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.

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.

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.

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.

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.

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.

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."

When the category-5 storm Hurricane Melissa struck Jamaica in October, its path crossed communities that had varying levels of preparedness. Many with maintained coastal protections, upgraded drainage and reliable early-warning systems had power and water restored in days. Others were immobilized for weeks.

When Specian dug into the data, he discovered that implementing energy-efficiency measures and shifting electricity usage to lower-demand times are two of the fastest and cheapest ways of meeting growing thirst for electricity. These moves could help meet much, if not all, of the nation's projected load growth. Moreover, they would cost only half-or less-what building out new infrastructure would, while avoiding the emissions those operations would bring.
