Regional Water Authority Urges Urban Water Providers to Take Action to Help the Lower American River

In response to the dry conditions in California, the Regional Water Authority (RWA) Board of Directors unanimously adopted a resolution on May 13 urging their urban water providers to take actions, such as asking customers to voluntary conserve and sustainably shifting to groundwater, to help the environment of the Lower American River. The RWA represents twenty (20) water providers serving two million people in the Sacramento region.

While the Sacramento region is in a strong position to meet the water supply needs of people, the dry conditions are expected to stress the environment of the Lower American River, one of our region’s greatest treasures.  Folsom Reservoir storage levels are lower than historic drought conditions in 2014 and 2015. Water flowing from Folsom Reservoir feeds the Lower American River and supports fish species that depend on both adequate flows and temperatures, including fall-run Chinook salmon and steelhead trout. RWA is continuing to work with the Sacramento Water Forum, and federal and state agencies, to monitor and address conditions.

Our local water providers are reducing their reliance Folsom Lake and the Lower American River for their water supplies as much as possible, and are taking actions such as:

  • 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. During dry years, the region’s groundwater aquifer is there to serve as our buffer against drought.
  • 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 customers to voluntarily conserve water by 10 percent, especially outdoors where most household water use occurs in the Sacramento region.

Our local providers are asking 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, but residents may be asked to further their efforts.

Responding to the worsening water supply conditions, the RWA will be increasing advertising to promote water efficiency and offering several new rebate programs to help customers install water-efficient irrigation, replace thirsty lawn with low-water plants, and fix household leaks.

We like to remind our customers and the public that we’ve been here before—and frankly will be here again with climate change. The region’s water providers have developed a comprehensive water resilience portfolio called WaterFuture, to prepare for the more frequent and intense cycles of drought projected to come with climate change.
