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.

Eyes In The Sky Help Farmers On The Ground

The Central Valley of California doesn’t begin so much with a gradual change in the landscape as with an abrupt line. Suddenly, a barren plain that looks like an apt cue for “The Good, the Bad and the Ugly” theme song is interrupted by the first row of leafy, irrigated crops.

Since the 1930s, the region has run on human control of water, carefully distributing the melting mountain snowpack through reservoirs and dams, pumping stations and irrigation pipelines, through drips, sprinklers and intentionally flooded fields.

Demise Of Key Environment Bill Could Escalate California’s Water Wars

The smoke has (partly) cleared from the legislative battlefield, in the aftermath of a struggle pitting the leader of the California Senate against not only powerful water and agricultural interests but also Gov. Gavin Newsom. And California’s two largest water-delivery systems may soon be operating under rules that differ ever more significantly.

Newsom has said he won’t approve Senate President Pro Tem Toni Atkins’ bid for a legal backstop against environmental rollbacks by the Trump administration. And Washington is poised to reduce protections for endangered fish species in the state’s largest watersheds.

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.

Will Climate Change Mean Less Farming in the West?

Colorado and California are rethinking water management for a hotter, drier future, while balancing urban water needs with the benefits agriculture brings to rural communities.

Most years, ranchers in Wyoming irrigate their land with water from the Green River—a tributary of the Colorado—in the summer so they have forage to feed their cattle late in the season.

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.

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

OPINION: East Coachella Valley Residents Speak Out For A Healthier Environment

The eastern Coachella Valley stands to benefit from a pair of Sacramento decisions. Now the state needs to hear from local residents.

In April, Gov. Gavin Newsom signed Executive Order N-10-10. It directs the California Natural Resources Agency, the California Environmental Protection Agency and the California Department of Food and Agriculture to recommend actions to help create climate-resilient water systems and healthy waterways as part of California’s Water Resilience Portfolio Initiative. This is a major step toward sustainable and equitable access to this precious resource during this climate crisis.
