In light of the crisis at Oroville Dam earlier this year, state regulators have begun ordering up-close inspections of aging dams throughout California. In a letter received by the San Luis Obispo County’s Public Works department on June 12, the chief of California’s Division of Safety of Dams ordered the county’s flood-control district to complete a “comprehensive condition assessment” of the Lopez Dam’s spillway. “We completed a reconnaissance-level assessment of the spillway at Lopez Dam and have noted that structure may have potential geologic, structural, or performance issues that could jeopardize its ability to safely pass a flood event,” the letter stated.

Love it or hate it, the Delta tunnels project is reaching a decision point. The state’s most powerful water agencies have set a September goal to decide whether they’re going pay for the biggest and most controversial water project California has undertaken since the 1960s: overhauling the plumbing system that pumps billions of gallons of water through the Sacramento-San Joaquin Delta to the Bay Area, Southern California and one of the nation’s most productive farm belts.

Kaylee Pineda likes to be outdoors. She rides her bike, plays Little League baseball and enjoys swinging on the monkey bars at school. But when the wind picks up and the air turns hazy, she knows she needs to stay indoors. The dust can suddenly trigger her asthma and leave her gasping for air. “I feel like my chest tightens,” Kaylee said. “My heart starts pumping.” Kaylee, who is 9 years old, uses an inhaler every morning before going to school and every night before going to bed.

Travelers driving through parts of the Sierra Nevada on Sunday were treated to some unexpected June weather: Snow. Chain controls were in effect on Sunday and overnight in Donner Pass on Interstate 80, but have since been lifted. A tweet from the National Weather Service in Sacramento said 5 inches of snow fell in Kingvale, in the Northern Sierra. Parts of Highway 50 and Lake Tahoe also received a dusting of snow. “That’s the one thing about the Sierras – it’s unpredictable,” said Caltrans spokeswoman Deanna Shoopman. “The weather can just change at the drop of a hat.”
