The last day of summer could bring snow to the Sierra, weather forecasters say. Thursday morning will see near-freezing temperatures and a 20 to 30 percent chance of precipitation in Sierra locales including Truckee, South Lake Tahoe, Reno and the higher elevations of Yosemite. Friday morning will be a little colder, under clear skies. Closer to the coast, a frost advisory has been issued for 3 to 8 a.m. Thursday in parts of Trinity and Mendocino counties, including Weaverville and Willits, the National Weather Service said. Temperatures there are expected to be in the low 30s.

The state’s largest pension fund on Tuesday shot down a pitch from a Republican lawmaker who wants it to study how much money it could save by cutting benefits for retired public workers. Sen. John Moorlach of Orange County in July wrote letters to CalPERS board members – Richard Costigan and Dana Hollinger – making two touchy requests for the pension fund. In one, Moorlach wanted CalPERS to estimate how much money it could save by temporarily suspending cost-of-living adjustments for retirees. CalPERS has different retirement plans that allow cost-of-living adjustments of 2 to 5 percent for its pensioners.

The west coast state will spend millions of dollars over the coming years on improving water quality and reducing waste. The deal signed with the Danish Ministry for Food and the Environment will provide the opportunity for Danish business to be involved in that development, the ministry said in a press statement. Minister Esben Lunde Larsen, who signed the agreement, said the Californian market was ideal for Danish water technology.

The pressure on California’s water supply during the recent drought was further complicated by outdated policy and antiquated infrastructure. There are multiple projects and policies in the process of getting funded or being approved that will address some of the water needs of the state. Executive Director for the California Water Alliance Aubrey Bettencourt explained that “we have this undersized, outdated water infrastructure system that hasn’t quite been updated since the ‘60s and ‘70s and it’s not able to keep up with our modern priorities, our modern requirements of it.”

A coalition of California environmental groups is calling on the California Department of Water Resources to build a complete, functional emergency spillway at Oroville Dam as part of a sweeping program to improve dam safety and flood control practices across the state and beyond. The conservation coalition — including Friends of the River, the California Sports Fishing Alliance, the South Yuba River Citizens League and American Whitewater — released a 53-page report seeking to apply lessons learned from February’s Oroville spillway crisis.
