The ag community at a Friday afternoon IID water conservation meeting wanted to know what the IID plans to change with water conservation payments projected to exceed the budget by $11.7 million. IID’s conservation needs under water transfer agreements with the San Diego County Water Authority and others are 303,000 acre feet. Of that, 103,000 acre feet comes from system conservation. The rest comes from on-farm water conservation.
California’s record snowpack is melting into significant runoff this summer, filling the state’s lakes and ponds with cold, fresh water. These flows usually help prevent blue-green algae blooms, which form in waterways and are toxic to humans and can be deadly to pets. But since mid-spring, there’s been reports of the dangerous — and stinky — algae blooms across the state. “It’s interesting — and maybe a bit surprising — that we do see these blooms even after these big winters,” said Keith Bouma-Gregson, manager of the California Freshwater Harmful Algal Blooms Program.
California, like many states, faces an infrastructure crisis, but not just the one affecting the roads we drive on, water systems we rely on, and the electricity that powers our everyday lives. As critical as it is for state and federal policy makers to focus on the resiliency of the state’s infrastructure, we also need to focus on a critical element that often is overlooked: the people who know how to build, maintain and operate the infrastructure we use every day.
Senators Dianne Feinstein (D-Calif.), Cory Gardner (R-Colo.), Martha McSally (R-Ariz.) and Kyrsten Sinema (D-Ariz.) today introduced the bipartisan Drought Resiliency and Water Supply Infrastructure Act, a bill to improve the nation’s water supply and drought resiliency. The legislation builds on Senator Feinstein’s 2016 California drought legislation that was included in the Water Infrastructure Improvements for the Nation (WIIN) Act. “The effects of climate change are here to stay, and one enormous effect on the West is more – and more severe – droughts,” said Senator Feinstein. “As California continues to recover from a historic drought, the Lawrence Berkeley National Laboratory now estimates that the Sierra snowpack, a primary source of water for California, will decrease by 79 percent by the end of the century.
San Diego looks ready to give up its money-losing plan to recycle plastic-foam food containers and packing material. A few years ago, as other cities were banning the material, commonly called Styrofoam, the San Diego City Council decided it would recycle the stuff instead. It knew then it would likely lose money, at least $90,000 a year. That may have been more palatable a few years ago because the city used to make several million dollars a year by selling other recyclables. City officials — lobbied hard by Dart Container Corporation, a plastics maker — also thought the loss was a small price to pay to make things easier on consumers and restaurant owners who preferred inexpensive, durable and insulating foam.
Cadiz operates a large agricultural property in California’s Mojave Desert at the base of a 1,300 square mile watershed with an aquifer system storing more water than Lake Mead. We currently irrigate the property with groundwater, but it’s a “tipping cup” and what we don’t use migrates to saline playas and evaporates—over 10 billion gallons lost annually. By managing the aquifer and this loss, Cadiz will sustainably provide new water to 400,000 Californians.
You might expect that plants hoping to thrive in California’s boom-or-bust rain cycle would choose to set down roots in a place that can store lots of water underground to last through drought years. But some of the most successful plant communities in the state — and probably in Mediterranean climates worldwide — that are characterized by wet winters and dry summers have taken a different approach. They’ve learned to thrive in areas with a below-ground water storage capacity barely large enough to hold the water that falls even in lean years.
Scientists have found a gigantic freshwater aquifer hidden deep below the ocean. The surprising discovery, from a new survey of the sub-seafloor off the northeast U.S. coast by researchers from Columbia University, appears to to be the largest formation of this type anywhere in the world — stretching from Massachusetts to New Jersey and extending continuously out about 50 miles to the edge of the continental shelf. Researchers said that if it was discovered on the surface it would create a lake covering some 15,000 square miles.
Recently Governor Newsom issued a call for a state portfolio of actions to manage water under rapidly changing climate and other conditions. Portfolio approaches attempt to integrate and balance a variety of actions (supply and demand management, surface water and aquifers) for single purposes (water supply, floods, safe drinking water) and often for multiple benefits, involving multiple interests. A previous essay reviewed the successes and limitations of portfolio approaches to water management in California
