The Arizona court issued an order prohibiting any state enforcement efforts against CFTC-regulated designated contract markets ('DCMs') on the grounds that state gambling laws are preempted as applied to transactions on DCMs.

If the lake level drops below 3,490 feet - termed the minimum power pool - the turbines that generate electricity have to be shut down. When the water level reaches critically low thresholds, air is sucked down like a whirlpool into the penstocks, forming explosive bubbles which can cause massive failure inside the dam.

Emergency crews arrived at the river near Davis Camp at about 11:15 a.m. on Monday for a possible drowning, having received reports that a man failed to resurface after entering the water from a pontoon boat.

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.

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.

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.

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.

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."

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.

"A dry January, which is historically the wettest month of the year in California, has now eroded the gains made at the start of the year and forecasts currently show no major precipitation in the next two weeks," California Department of Weather Resources spokesperson Jason Ince wrote in a Jan. 30 news release. The first month of the year certainly left the area warmer and drier than usual, weather officials confirmed.
