Droughts usually evoke visions of cracked earth, withered crops, dried-up rivers and dust storms. But droughts can also form over oceans, and when they then move ashore they are often more intense and longer-lasting than purely land-born dry spells.
Researchers at the University of California San Diego report in a new study a way to improve groundwater monitoring by using a remote sensing technology (known as InSAR), in conjunction with climate and land cover data, to bridge gaps in the understanding of sustainable groundwater in California’s San Joaquin Valley.
Despite little precipitation and a small snowpack in the 2020 water year, which ended Sept. 30, California weathered the year on water stored in reservoirs during previous years’ storms. Going into 2021, farmers note that weather officials predict a La Niña climate pattern in the Pacific Ocean, which has brought drought conditions in the past.
Unforeseen conditions caused a change order to the Fallbrook Public Utility District contract to replace the pipeline along Winter Haven Road, but it was the only change order needed in the contract to replace approximately 2,570 feet of pipeline. The Sept. 28 FPUD board meeting included a 5-0 vote to approve the change order and also to approve the notice of completion for the project.
A report by California energy officials on Tuesday placed blame for rolling blackouts that left millions without power in August on the impact of climate change and outdated policies and practices that failed to adequately take into account hotter weather.
If the state has any hope of heading off a looming “tidal wave” of residential water shut offs and bankrupt water systems it has to get a picture of current impacts, advocates urged.
On the heels of a historic drought, at the beginning of the implementation of historic groundwater legislation, and in light of potential flooding, Porterville will have more water in the future and a larger dam to prevent it from damaging the city below. On Sept. 29, the U.S. Army Corps of Engineers Sacramento District, along with local and federal partners, have broken ground on the Tule River Spillway Enlargement Project at Success Lake near Porterville, Calif.
California energy officials on Tuesday said the state’s power planning processes were insufficient to address a crushing heat wave in August that led to rolling blackouts for two days. In a preliminary analysis that was requested by Gov. Gavin Newsom, the heads of three state energy bodies said there was no single cause of the outages.
