Future Precipitation Increase from Very High Resolution Ensemble Downscaling of Extreme Atmospheric River Storms in California

Precipitation extremes will likely intensify under climate change. However, much uncertainty surrounds intensification of high-magnitude events that are often inadequately resolved by global climate models. In this analysis, we develop a framework involving targeted dynamical downscaling of historical and future extreme precipitation events produced by a large ensemble of a global climate model. This framework is applied to extreme “atmospheric river” storms in California.

The Most Powerful Renewable Energy

The world’s most relied-upon renewable energy source isn’t wind or sunlight, but water. Last year, the world’s hydropower capacity reached a record 1,308 gigawatts (to put this number in perspective, just one gigawatt is equivalent to the power produced by 1.3 million race horses or 2,000 speeding Corvettes). Utilities throughout the globe rely upon hydropower to generate electricity because it is cheap, easily stored and dispatched, and produced with no fuel combustion, meaning it won’t release carbon dioxide or pollutants the way power plants burning fossil fuels such as coal or natural gas do.

San Diego Regional Water Projects Awarded $15M from State

The California Department of Water Resources has awarded more than $15 million in grant funds to advance several regional water projects in San Diego County, ranging from water recycling and reuse to water conservation.

The San Diego County Water Authority submitted the funding request on behalf of the San Diego Integrated Regional Water Management Program, or IRWM. The San Diego IRWM Program began in 2005 as an effort by water agencies, wastewater agencies, stormwater and flood managers, watershed groups, business leaders, disadvantaged communities, tribes, agriculture, and nonprofit stakeholders to improve water resources planning in the region.

Colorado River Stakeholders To Face Tribal Rights, Environmental Protection and Climate Change

Charismatic is hardly the best word to describe the humpback chub, a fish with a frowny eel face jammed onto a sportfish body in a way that suggests evolution has a sense of humor. Nor did tastiness build a fan base for this “trash fish” across its natural habitat throughout the Colorado River Basin. But, in 1973, the humpback chub became famous by winning federal protection under the Endangered Species Act.

State Water Department Grants Over $15M to San Diego Projects

SAN DIEGO COUNTY, Calif. — The California Department of Water Resources awarded more than $15 million in grant funds for several water projects in San Diego County, officials announced Wednesday.

The seven projects range from water recycling and reuse to water conservation and from as far south as National City up to Oceanside and Fallbrook.

U.S. Senator Kamala D. Harris Introduces Legislation to Ensure Nation’s Water Sustainability – Says Our Nation is Facing a Water Safety and Affordability Crisis

U.S. Senator Kamala D. Harris (D-CA) on Tuesday announced the introduction of the Water for Tomorrow Act, legislation that ensures the nation’s water supply is safe and sustainable. The threat of climate change, which has a disproportionate impact on low-income communities and communities of color, will continue to intensify water scarcity and extreme weather conditions, particularly in California and the West. The Water for Tomorrow Act combines the water sustainability measures from Sen. Harris’ Water Justice Act with key measures from the FUTURE Drought Resiliency Act, led in the House of Representatives by Rep. Jared Huffman (D-CA).

Sacramento Region Plans to Store Water Underground as a Climate Change Adaptation Strategy

The Sacramento region is preparing for the long term impacts of the climate crisis when it comes to water supply. Central to the plan is a groundwater storage program with two to three times the space of Folsom Lake.

As the climate warms it’ll likely become harder to fill up reservoirs, because the snowpack could be small for multiple years. Think of the nearly empty reservoirs across California during the most recent drought.

State Awards $15 Million for San Diego Regional Water Projects

The California Department of Water Resources has awarded more than $15 million in grant funds to advance several regional water projects in San Diego County, ranging from water recycling and reuse to water conservation.

The San Diego County Water Authority submitted the funding request on behalf of the San Diego Integrated Regional Water Management Program, or IRWM. The San Diego IRWM Program began in 2005 as an effort by water agencies, wastewater agencies, stormwater and flood managers, watershed groups, business leaders, disadvantaged communities, tribes, agriculture, and nonprofit stakeholders to improve water resources planning in the region.

The statewide IRWM Program is supported by bond funding from the California Department of Water Resources to fund competitive grants for projects that improve water resources management.

Collaboration with county agencies, nonprofits improves water supply and conservation

“These grants will provide much-needed funding for important local water supply projects and water-use efficiency measures, along with a disadvantaged community project in National City,” said Water Authority Board Chair Jim Madaffer. “Regional collaboration by the Water Authority and a host of partners makes these projects possible. Once again, this shows how San Diego County is stronger together.”

Madaffer praised the San Diego IRWM Regional Water Management Group and the Regional Advisory Committee for their work over the past year to secure the $15,336,336 grant. Since 2008, the San Diego region has secured more than $111 million in funds for 74 high-priority water management projects through the IRWM process. The projects help to achieve goals established in the San Diego IRWM Program and the Water Authority’s Urban Water Management Plan.

The following regional water projects will receive funding in the current round:

  • Paradise Valley Creek Water Quality and Community Enhancement, City of National City, Flood Damage Reduction, $3,681,056
  • Pure Water Oceanside, City of Oceanside, Water Supply–Groundwater, $3,115,000
  • North County Recycled Water Project, San Elijo Joint Powers Authority, Water Supply–Recycled Water, $2,820,000
  • North City Pure Water Facility Influent Pump Station and Conveyance Pipeline, City of San Diego, Water Supply–Recycled Water, $1,477,600
  • 2020 Regional Water-Use Efficiency Programs, San Diego County Water Authority, Water Conservation, $1,440,000
  • San Elijo Stormwater Capture & Reuse, San Elijo Joint Powers Authority, Water Supply–Recycled Water, $1,195,000
  • Lower Santa Margarita River Indirect Potable Reuse Pilot Project, Fallbrook Public Utility District, Water Supply–Recycled Water, $687,500

In addition, the grant allocates $920,180 to the Water Authority to administer the grant.

Regional approach to create resilient and diverse water supply portfolio

“By working together for more than 12 years, the regional IRWM Program has created a legacy of collaboration by public agencies and nonprofit organizations in the region to increase the long-term reliability and resiliency of the San Diego region’s water supply and diversify our local supply,” said Mark Stadler, San Diego regional IRWM program administrator. “Investing in water reuse, water efficiency, and conservation projects are key parts of our success to ensure a regional approach to integrated watershed management.”

On November 4, 2014, California voters approved Proposition 1, the Water Quality, Supply, and Infrastructure Improvement Act of 2014. Proposition 1 authorized $510 million in IRWM funding. Funds are allocated to 12 hydrologic region-based funding areas.

The Proposition 1 IRWM Grant Program, administered by DWR, provides funding for projects that help meet the long-term water needs of the state, including:

  • Assisting water infrastructure systems adapt to climate change;
  • Providing incentives throughout each watershed to collaborate in managing the region’s water resources and setting regional priorities for water infrastructure; and
  • Improving regional water self-reliance, while reducing reliance on Sacramento-San Joaquin Delta.

“Water is such a vital resource, that it is critical we continue to take action to ensure communities have access to clean water supplies, reliable flood protection and healthy ecosystems.” said DWR Director Karla Nemeth when announcing the San Diego regional grant on July 3. “These grants will support agencies and projects to continue local momentum in creating a more diverse water supply portfolio, strengthening partnerships and addressing climate change.”

California Megadrought? Not If You Look at Precipitation

If you want to know what climate change means for California’s water supply, consider the last two Februaries. In 126 years of statewide record-keeping, you can’t find a drier February than the one we just experienced. But February 2019 was the third-wettest on record.
