La Presa de Otay Lakes tuvo que abrir sus compuertas para disminuir el nivel de agua que ya había llegado a su máxima capacidad en los últimos seis años provocado por las intensas lluvias registradas en el condado de San Diego. La reserva alcanzó su límite y autoridades decidieron desfogar la presión hacia el Río Otay, informó la vocera de la ciudad Alma Rife. Según registros de la ciudad, la presa puede contener casi 49 mil 849 pies cuadrados de agua y para el lunes ya se había reportado que había llegado al93 por ciento de su capacidad.

The plan to remove four hydroelectric dams to improve fish passage and water quality on the Klamath River is proceeding on schedule for a 2020 demolition time, according to plan proponents. The Federal Energy Regulatory Commission will ultimately have to approve or deny the plan, and the change in administration in Washington, D.C., has led to three of the five seats on the commission being vacated. President Donald Trump will be responsible for appointing the three new members, but plan proponents such as the dams’ owning company PacifiCorp, do not believe this will affect the project’s timeline.
In the late 1980s, a Japanese scientist named Koji Minoura stumbled on a medieval poem that described a tsunami so large it had swept away a castle and killed a thousand people. Intrigued, Minoura and his team began looking for paleontological evidence of the tsunami beneath rice paddies, and discovered not one but three massive, earthquake-triggered waves that had wracked the Sendai coast over the past three thousand years. In a 2001 paper, Minoura concluded that the possibility of another tsunami was significant.
President Trump stepped up his attack on federal environmental protections Tuesday, issuing an order directing his administration to begin the long process of rolling back sweeping clean water rules that were enacted by his predecessor. The order directing the Environmental Protection Agency to set about dismantling the Waters of the United States rule takes aim at one of President Obama’s signature environmental legacies, a far-reaching anti-pollution effort that expanded the authority of regulators over the nation’s waterways and wetlands.
The Kings River’s overflow system in western Fresno County cannot carry as much floodwater as it once did, so there is greater risk of flooding in this wet year, Fresno County supervisors were told on Tuesday. The problems led to approval of an emergency proclamation by supervisors that will allow officials to seek state help in an all-out effort to improve the county’s slough and levee system and any new problems that could arise from flooding over the next few months.
The drought-busting snow and rain in the mountains around Lake Tahoe have pushed the lake to its highest level in more than a decade. After five years of drought, the alpine lake atop the Sierra Nevada now has enough water to fill downstream reservoirs and meet the Reno area’s needs for at least two years, hydrologists say. “We are basically going from one extreme to the other in two years,” said Bill Hauck, senior hydrologist for the Truckee Meadows Water Authority.
Valley farmers like Joe Del Bosque, whose situation was spotlighted recently in the Los Angeles Times, was begging for and buying water during last year’s drought at $1,000 to $1,300 per acre-foot after federal water officials failed to make good on water allocation contracts.These farmers thought themselves lucky to find willing sellers. But now it looks like their luck will run out courtesy of their perennial but faithless friend and occasional foe, the federal government.
It’s been about 13 years since San Diego received as much rain as it recorded on Monday, when the region was clobbered by an unexpectedly large storm. San Diego International Airport recorded 2.34” of rain on Monday — a figure that’s higher than the 2.19” that the city averages for the entire month of February. The National Weather Service says the airport hasn’t received that much rain since October 27, 2004, which it got 2.70”. “We got a real deluge,” said Steve Harrison, a weather service forecaster.
After flows down Oroville Dam’s fractured main spillway were dialed back to nothing Monday afternoon, heavy equipment operators worked through the night to clear the massive debris pile that has formed at the base of the damaged concrete structure. The efforts to open the channel below the spillway, which will allow engineers to once again fire up the dam’s hydroelectric plant, appear to be paying off, said Nancy Vogel, a spokeswoman for the California Natural Resources Agency.
When California state biologists crested a sandbar along the Feather River on Tuesday morning, they expected to find at least some of the water that just a day before had raged through the channel, too deep to stand in – and plenty of fish needing to be rescued. Instead, to their chagrin, the flows powering down Oroville Dam’s badly damaged main spillway into the Feather River had been throttled back so quickly Monday that the whole sandbar was now dry. “Oh, no,” said biologist Alana Imrie.
