Climate Change: Strengthening Atmospheric Rivers

Ahead of the United Nations Climate Summit next week, 10News is diving deeper into the affects of climate change. Climate change is leading to more dangerous and deadly wildfires and so often after fires scorch the ground in the fall, the heavy winter rains in atmospheric rivers lead to mudslides and flooding.

The scary reality is that these types of storms are going to get stronger. According to Alexander Gershunov, a research meteorologist at the Scripps Institution of Oceanography at UCSD, “we know for certain that atmospheric rivers are going to get stronger in the future, in a warmer atmosphere more water vapor can be held so atmospheric rivers are basically plumes of very intense concentrated moisture and they just going to get wetter as they get warmer.

Rare California Trout Species Returns To Native Habitat

For the first time in nearly a century, a rare California trout species will swim in a mountain creek that is its native habitat, marking a major milestone that conservationists hope will lead to a thriving population and removal of its threatened status.

About 30 Paiute cutthroat trout will be plucked Wednesday from Coyote Valley Creek in the eastern Sierra Nevada wilderness and hauled in cans strapped to pack mules about 2 miles west into Long Valley.

 

Pipeline 4 Repairs Underway In North San Diego County

A recently discovered leak in a section of a pipeline in North County will be repaired in coming months while Pipeline 4 returns to service.

Crews have installed bulkheads in the pipeline to isolate a portion of Pipeline 4 for repairs. This will allow the pipeline to continue treated water deliveries throughout the county in a modified fashion starting the week of Sept. 16 and restores full service to retail water agencies. With the leaky section isolated, crews will make necessary repairs.

Four Water Authority member agencies – Fallbrook PUD, Rainbow MWD, Valley Center MWD, and Vallecitos Water District – have taken steps to manage water supplies while the pipeline was shut down to install the bulkheads.

OPINION: How Bill Defends Against Trump Environmental Rollbacks

If you’re a local and have hosted a visitor to San Diego, you’ve probably felt pride as you’ve guided people to take in Coronado Beach, Pacific Beach, La Jolla Cove, our parks and swimming holes along Mission Bay, and perhaps the new and growing waterside paths along Chollas Creek. Our beaches, bays and waterways are central to who we are as San Diegans and to our unique way of life. But in a heavily urbanized region clean water doesn’t just happen; it takes hard work and stewardship.

OPINION: Why Atkins Bill Would Hurt California’s Water Progress

California’s contemporary effort to modernize the water system in the Sacramento-San Joaquin Delta officially began in 2006.

George W. Bush was president of the United States and Arnold Schwarzenegger was governor of California. Their administrations signed a planning agreement. And the search for a solution was on.

Thirteen years, two governors and two presidents later, we are all still at it.

A Brief History Of Pure Water’s Pure Drama

After years of scientific progress, regulatory wrangling, political ups and downs, and searching for the money, San Diego is getting ready to get to work on a multi-part, multibillion-dollar project that will eventually provide a third of the city’s drinking water.

San Diego water officials have looked at turning sewage into drinking water for nearly 40 years. The first stab at recycling wastewater involved a series of ponds in Mission Valley that grew hyacinths, long-rooted plants that gobble up sewage and leave relatively clean water behind.

West Basin MWD Completes Recycled Water Pump Station Improvements Project

Carson-headquartered West Basin Municipal Water District (WBMWD) recently announced the completion of its recycled water Pump Station Improvements Project, targeting enhanced local water supply and sustainability. The almost $18 million project includes the construction of a new pump station and the installation of a three-megawatt emergency generator at the most critical component of the WBMWD’s renowned water recycling program.

“Forward thinking investments in West Basin’s infrastructure allow the district to serve its recycled water customers and communities with a continuous flow of locally produced recycled water,” said WBMWD Board President Scott Houston.

San Diego City Council Takes The Leap Into Community Choice Energy

The city of San Diego is about to enter the power-purchasing business.

On a 7-2 vote Tuesday afternoon, the San Diego City Council approved the formation of a community choice aggregation, or CCA, energy program. The council also approved a joint powers agreement that will see San Diego partner with Chula Vista, La Mesa, Encinitas and — by all indications — Imperial Beach to take the place of San Diego Gas & Electric when it comes to purchasing sources of electricity within their jurisdictions.

 

City of San Diego Draws On Local Water Supplies After Deliveries Reduced

Due to an unexpected reduction in imported water from the Metropolitan Water District of Southern California (MWD), the City of San Diego was obligated to dip into its local water supplies to continue service to customers.

On Tuesday morning, algae clogged a filter screen on a major pipeline, causing an interruption in raw, untreated water from MWD to the San Diego County Water Authority. MWD cleared the pipeline that morning and full deliveries resumed by early afternoon. The City of San Diego purchases its imported water from the County Water Authority.

 

Another Day Of Dry, Gusty Fire Weather Ahead For San Diego Region

Dry conditions and gusty winds will increase the danger of fire in San Diego County on Tuesday, according to the local office of the National Weather Service.

A trough of low pressure moving in from the north will bring cooler temperatures throughout the workweek, but will also bring gusty winds blowing to the west, meteorologist Bruno Rodriguez said.

Humidity levels will drop to between 10% to 15% in the San Diego County mountains and deserts, forecasters said. Wind gusts could reach 35 mph in those two areas
