Along the West Coast, 40-60% of annual precipitation and nearly 85% of flooding events are caused by atmospheric river (AR) storms. Federal policy now allows water managers to incorporate forecasted conditions into their water operations through updates to the Water Control Manuals. CW3E at Scripps Institution of Oceanography leads a variety of contemporary, science-based Atmospheric River and Forecast-Informed Reservoir Operations (FIRO) programs and projects to optimize weather, climate and water forecasts—providing water managers with practical tools to improve their operations, increase water supplies, and promote public safety. Membership represents an opportunity to guide research strategies on improved operational tools to support core water management services.

East Bay Municipal Utility District is committed to providing reliable, high-quality drinking water and wastewater service through sustainable activities that avoid, minimize or mitigate adverse effects to the environment and the public. Sustainability and resilience are essential principles that guide the actions of EBMUD in meeting the needs of customers.

Fresno Metropolitan Flood Control District provides to the citizens living within its boundaries, the ability to control and manage the flood, storm, and surface and groundwater resources of the area so as to prevent damage, injury, and inconvenience; to conserve such waters for local, domestic and agricultural use; and to maximize the public use and benefit of the District’s programs and infrastructure.

Irvine Ranch Water District (IRWD) is dedicated to providing, conserving, and maximizing the efficient use and reuse of water and renewable resources to benefit their customers and to enhance the environment. IRWD manages its supply and demand with careful research and analysis regarding flow, diversions, climate, customer demand and population estimates to ensure there will be an adequate supply of clean, reliable water.

Orange County Water District’s (OCWD) ability to reduce reliance on imported water depends on increasing capture of storm water released from Prado Dam. Current flood control manuals allow temporary capture of up to 20,000 acre-feet of water. With CW3E, advancing research observations for unique region-specific forecasts may permit Prado Dam to capture up to 30,000 acre-feet of water behind the dam and direct it to groundwater recharge.

San Bernardino Valley Municipal Water District (SBVMWD) has led the effort to enhance groundwater storage throughout the upper Santa Ana River Watershed.  As climate change influences the hydrologic cycle, water managers need to prepare for potentially extreme shifts in precipitation. By collaborating with CW3E, SBVMWD is preparing for maximum adaptation and resiliency in the face of unknown future conditions.  SBVMWD plans to collaborate with CW3E to assess both risks and opportunities for various groundwater recharge projects and incorporate Forecast-Informed Reservoir Operations (FIRO) modeling into water resource planning.

San Diego County Water Authority is working with CW3E to assess how better precipitation forecasts at a range of timescales can improve reservoir management in the San Diego region- maximizing local water supply and the reliability of water resources and improving the ability of water managers to make real-time decisions for managing limited water supplies.

San Francisco Public Utilities Commission (SFPUC) depends on accurate weather forecasts to optimize management of water resources by meeting competing objectives including maximizing water supply, ensuring dam safety, environmental stewardship, green hydropower production and recreation. CW3E models and data products provide critical information for the management of the SFPUC reservoirs and dams.

Salt River Project (SRP) was established in 1903 to coordinate the management of water supplies for shareholders of the Salt River Valley Water Users’ Association in Arizona. Over the past 100+ years, SRP’s expertise has grown into the conjunctive management of the 13,000-square-mile Salt River and Verde River watersheds that produce SRP’s surface water supplies; seven dams and reservoirs; more than 260 groundwater wells; three water-banking projects; and a vast electric generation, transmission and distribution system spanning multiple states to serve a 2,900-square-mile electric and 375-square-mile water service area in central Arizona. SRP strives to protect the water rights of its shareholder while also protecting the Salt and Verde river watersheds in a way that benefits all of those who depend on these rivers. This includes conducting research, working on watershed restoration efforts, and collaborating with water users and communities across the state.

Sonoma Water (SW) is responsible for wholesale water supply, flood risk management, and wastewater management. Because these operations are significantly impacted by ARs, SW has partnered with CW3E to assist in various applied research programs and other programs to help mitigating such impacts. Specifically, SW is partnering with CW3E on leading the implementation of FIRO at Lake Mendocino resulting in several major deviations being approved by the US Army Corps of Engineers to save up to 11,650 acre feet of water annually.

Turlock Irrigation District’s (TID) ability to protect against flood events depends on being able to more accurately forecast large rain events. In both 2017 and 2019, CW3E models gave TID time to create space in the reservoir through pre-flood releases to minimize the effects of storms forecasted to hit the area. In 2018, a dry year, the accuracy of CW3E models to forecast extreme weather events gave TID confidence to hold on to 150,000 acre-feet of water that would have been released otherwise.

Valley Water is committed to providing Silicon Valley safe, clean water for a healthy life, environment, and economy. Valley Water’s vision is to be nationally recognized as a leading water resources management agency.

Yuba Water Agency is dedicated to continuing to improve water supply management, especially reducing the risk of flood events. CW3E atmospheric river forecasting enhancements are being used to complement Yuba Water’s plans to build a $225 million secondary spillway at New Bullards Bar Dam, to provide early reservoir flood releases. The combination of new infrastructure and forecasting improvements is increasing public safety for the Yuba-Feather and surrounding regions.
