Thursday Top of the Scroll: Powerful El Niño puts California in the bull’s-eye for soaking winter, models show

One of the world’s top climate models puts a bull’s-eye on the California coast as El Niño strengthens, with a greater than 90% chance of above-normal precipitation from December through February. There’s at least a 70% chance of well-above-normal precipitation. That outlook is from the European Center for Medium-Range Forecasts, which on Wednesday released its first full supercomputer forecast that includes 51 model simulations of winter. … In California, a run-of-the-mill storm this winter may be a few degrees warmer than in a typical year as mild, tropical air is directed toward the state. That means pushing the snow line up hundreds of feet higher in the Sierra Nevada.

Kern’s golden mussel fight expected to cost $36 million annually

No silver bullets to eradicate golden mussels were revealed at a symposium on the invasive species held Wednesday by the Water Association of Kern County and Kern County Farm Bureau. But participants got a solid overview of what water districts have learned so far – what’s worked, what to look out for and how big the bill is expected to be Agricultural water districts in Kern have spent about $9 million combined trying to keep the rapidly reproducing, pipe clogging little mollusks at bay, according to Stacy Kuwahara, Assistant County Administrative Officer.

Why Lake Havasu, Colorado River’s party lake, isn’t allowed to run out of water

At this point, it’s old news to say that the Colorado River is in crisis. … But on nearby Lake Havasu, the water’s not just fine; it’s perfect for an endless summertime party. … The discord is a side effect of the complex series of compacts, court decisions, federal laws and other regulations that guide policy along the Colorado River. … Because Lake Havasu must maintain a certain elevation to keep water flowing into the [Colorado River] aqueduct, which provides water to some of the most powerful water users in the Colorado River system, the lake’s surface elevation typically stays between 445 feet and its maximum of 450 feet. Water is also diverted from the lake for the Central Arizona Project, which carries river water to Phoenix and Tucson.

Wetlands

Sacramento National Wildlife RefugeWetlands are among the world’s most important and hardest-working ecosystems, rivaling rainforests and coral reefs in productivity. 

They produce high oxygen levels, filter water pollutants, sequester carbon, reduce flooding and erosion and recharge groundwater.

Bay Model

Operated by the U.S. Army Corps of Engineers, the Bay Model is a giant hydraulic replica of San Francisco Bay and the Sacramento-San Joaquin Delta. It is housed in a converted World II-era warehouse in Sausalito near San Francisco.

Hundreds of gallons of water are pumped through the three-dimensional, 1.5-acre model to simulate a tidal ebb and flow lasting 14 minutes.

Salton Sea

As part of the historic Colorado River Delta, the Salton Sea regularly filled and dried for thousands of years due to its elevation of 237 feet below sea level.

The most recent version of the Salton Sea was formed in 1905 when the Colorado River broke through a series of dikes and flooded the seabed for two years, creating California’s largest inland body of water. The Salton Sea, which is saltier than the Pacific Ocean, includes 130 miles of shoreline and is larger than Lake Tahoe

Lake Oroville shows the effects of drought in 2014.

Drought

Drought — an extended period of limited or no precipitation — is a fact of life in California and the West, with water resources following boom-and-bust patterns. No portion of the West has been immune to drought during the last century and it occurs with much greater frequency in the West than in any other region of the country.
