Media Statement: Declaration Underscores Region’s Drought Concerns, Actions to Protect the Lower American River

Posted on Monday, May 10th, 2021

Sacramento, Calif.The following statement was released today by Jessica Law, Executive Director of the Water Forum, and Jim Peifer, Executive Director of the Regional Water Authority, in response to Gov. Gavin Newsom’s Proclamation of a Drought State of Emergency, expanding the emergency to 41 counties, including those in the Sacramento region.

“Earlier in the year, we were cautiously optimistic that near-average snowpack levels in the upper watershed would provide a buffer for Folsom Reservoir. However, inflow levels are lower than expected and predicted. Folsom Reservoir storage levels are lower than historic drought conditions in 2014 and 2015, and this year’s near-average snowpack is evaporating or soaking into the soil rather than flowing into Folsom Reservoir.

“Water flowing from Folsom Reservoir feeds the Lower American River and supports recreation and supports fish species such as fall-run Chinook salmon and Central Valley steelhead trout that depend on both adequate flows and temperatures.

“While the Sacramento region is in a strong position to meet the water supply needs of people, the Drought Emergency Proclamation released today underscores how dry conditions are looking increasingly dire for the environment of the Lower American River.

“Applying the lessons learned during California’s most recent historic drought, the Sacramento Water Forum, which brings together water providers, environmental groups, and local government and business groups, and the Regional Water Authority, working with local water providers, have been coordinating with each other, as well as federal and state agencies, on the possibility of drought this year and what can be done to alleviate its effects.

“Actions include:

  • Working with the U.S. Bureau of Reclamation, which manages Folsom Reservoir, and other state and federal partners, to preserve as much water as possible in the reservoir to support the health of the river and water supply reliability.

 

  • Shifting to using more groundwater: Over the past several decades local water providers have been working together to sustainably shift the region’s water use to surface water or groundwater according to conditions. This has allowed more groundwater to be available for dry times. We know this approach works as demonstrated during the most recent drought when the Sacramento region used more groundwater than typical to leave more in our waterways for fish and wildlife (see graph at right). In the wet years since the last drought, when there was surplus water beyond environmental needs, more surface water was used and the groundwater basin recovered. Since this is a dry year, we are planning to use more groundwater than normal in 2021.

 

  • Sharing water around the region: Since the last drought, water providers have invested in new pipelines, interties, pumps and groundwater wells to move water where it’s needed. This system builds on the existing ability to shift between surface and groundwater and is ready to assist the communities most directly impacted by lower levels at Folsom Reservoir.

 

  • Asking residents to be vigilant about stopping water waste: We ask residents to use water efficiently no matter the weather, and regional water use is already lower than it was in 2013, before the last major drought. Now, residents must be even more focused on efficiency and stopping water waste.

“In addition, the Sacramento Water Forum is increasing its monitoring of fish conditions in the Lower American River to help inform decisions by federal and state agencies, and is implementing its 10th habitat restoration project in the river near Ancil Hoffman Park in Carmichael to improve conditions for salmon and steelhead spawning and rearing.

“There is no doubt that many challenges lie ahead for the environment of the Lower American River this year. We appreciate the collaboration and partnership with the U.S. Bureau of Reclamation to help ensure sufficient storage in Folsom and adequate flows in the Lower American River.

“Beyond this year, we’re working hard to prepare for the more frequent and intense cycles of drought projected to come with climate change.

“The region’s water providers have developed a comprehensive water resilience portfolio called WaterFuture, which encompasses our entire ‘supershed’ from the mountain tops of the American River watershed to the groundwater basin below the valley floor.

Formed in 2001, its primary mission is to help its members protect and enhance the reliability, availability, affordability and quality of water resources. Learn more at rwah2o.org.

The Sacramento Water Forum is a diverse group of business and agricultural leaders, citizen groups, environmentalists, water managers and local governments working together to balance two co-equal objectives: to provide a reliable and safe water supply for the Sacramento region’s long-term growth and economic health; and to preserve the fishery, wildlife, recreational, and aesthetic values of the lower American River.

Media Statement: Sacramento Region Ready to Address Grim Forecast

Posted on Tuesday, March 23rd, 2021

Sacramento, Calif.The following statement was released today by Jim Peifer, Executive Director of the Regional Water Authority, and Jessica Law, Executive Director of the Water Forum, in response to announcements by the U.S. Bureau of Reclamation and California Department of Water Resources about very low water allocations in 2021.

“The announcements today sound the alarm about just how dry conditions are around the state.

“For the last several months, the Regional Water Authority, working with local water providers, and the Water Forum, which brings together water providers, environmental groups, and local government and business groups, have been coordinating with each other, as well as federal and state agencies, on the possibility of drought this year and what can be done to alleviate its effects. As we move toward April, it has become increasingly clear that this will be a serious dry year.

“We are continuing to work together to understand the scope of impacts on the Lower American River, and the region. Recognizing that this is the second dry year in a row, we are looking ahead, knowing that dry conditions in 2021 and beyond could have lasting impact.

“While managing a worsening water supply situation on top of an ongoing health crisis may seem daunting, it’s important to recognize that we’ve been here before—and frankly, we will be here again. The positive news is that the Sacramento region is in a stronger position to meet human and environmental needs in consecutive dry years, which are becoming a more frequent and intense part of life in California due to climate change.

“Since the last drought, when water levels in Folsom and the Lower American River dropped to historically low levels, local water providers have implemented nearly 20 projects—from new pipelines that move water across communities to pumps that can move water in new directions—all designed to strengthen the Sacramento region’s resiliency to drought conditions.

“The region is working together to identify additional actions that can be taken in the next few months to reduce the region’s reliance on Folsom Reservoir, protect the health of the Lower American River, and continue to serve the communities in our region.

“Plans include:

  • Shifting to using more groundwater: Over the past several decades local water providers have been working together to strategically shift the region’s water use to surface water or groundwater according to availability. This has allowed more groundwater to be available for dry times. This approach was successful during California’s most recent drought. For example, the Sacramento region used more groundwater than typical in order to leave more in our waterways for fish and wildlife. We are planning to do the same in 2021.
  • Sharing water around the region: Since the last drought, water providers have invested in new pipelines, interties, pumps and groundwater wells to move water where it’s needed. This system is ready to assist the communities most directly impacted by lower levels at Folsom.
  • Asking customers to be vigilant about stopping water waste: We ask our customers to use water efficiently no matter the weather. Now, they must be even more focused on efficiency and stopping water waste. During the last drought, local residents reached some of the state’s highest conservation rates and ultimately contributed 12 percent of the state’s total water savings even with only 5 percent of the population. We know our customers will answer the call to conserve when needed.

“We appreciate the collaboration and partnership with the U.S. Bureau of Reclamation, which operates Folsom Reservoir, to help ensure sufficient storage in Folsom and adequate flows in the Lower American River for local drinking water and environmental needs while working to meet water needs elsewhere. We are also ready to work in coordination with state agencies to help make sure the state’s water needs can be met.

“Beyond this year or even next, we’re working hard to prepare for the more frequent and intense cycles of drought projected to come with climate change.

“The region’s water providers have developed a comprehensive water resilience portfolio called WaterFuture, which encompasses our entire ‘supershed’ from the mountain tops of the American River watershed to the groundwater basin below the valley floor.
