For all of the high-tech advancements California is famous for, one part of the state's infrastructure – providing enough water for its environment, cities and farms – is lacking. It has been more than four decades since the last major water storage facility was built in the Golden State, and our total population has nearly doubled since that time.

Proposed for the west side of the Sacramento Valley, Sites Reservoir provides an opportunity to dramatically boost water storage capability, which would help safeguard the state during drought, like what we are currently enduring.

Sites would provide up to 1.5 million acre-feet of additional water storage, with a dedicated supply of water for environmental uses,  including a significant amount of water for our state's wildlife refuges, particularly in dry years, to support the ducks, geese and other wildlife who greatly rely on our system of refuges to survive and thrive.

The Public Policy Institute of California (PPIC) is not taking a position on Sites. They do have an interesting concept to help the environment, should the project be completed – an environmental water budget.

"This approach to water for the environment would have really big advantages," said PPIC Senior Fellow Jeff Mount. "Right now, the way we manage everything, it's all set on minimum in-stream flow and water quality standards. It's kind of like a hydrologic flatline- it doesn't change enough.  We're suggesting that the most efficient and effective use of water has to have some flexibility in that use – especially if you want to mete it up with investments in physical habitat.  That's why we're promoting an ecosystem water budget managed by a trustee of some kind –a restoration administrator like on the San Joaquin River. This is probably the best way to go. It's nimble. It sets the environment as a partner, working with the people who are managing the operations of storage all the time. And there's certainty. The key bottom line is the flexibility this would bring."

Sites would also provide more water for urban needs, something very appealing to many, including General Manager Valerie Pryor of Zone 7 Water Agency, which serves the East Bay Area.

"Our community places a lot of value on increasing water storage and especially the Sites Reservoir," Pryor remarked. "Our board and community are excited about this prospect. Seventy percent of our water comes from the State Water Project, and that supply is increasingly less reliable. Also, we are not all the way to build out, so we do expect to add population over the next 30 years, so we need additional water supply – both to make up for decreasing reliability and also for growth. The Sites Reservoir really helps with that equation."

This enthusiastic support, plus increased momentum from favorable state and federal reviews of the project, are welcome developments for those trying to get this reservoir built – including the top person tasked for this job. "I am 100 percent confident that Sites Reservoir will be built," remarked Jerry Brown, General Manager of the Sites Project Authority. "It must be built. The thing that we are striving for, and I believe is a need in order to proceed, is that we must do this together."

Episode Transcript

Kai Tawa: We had a really good start to the water year with that atmospheric river event in late October. A lot of the valley got somewhere between 4 to 8 inches of rain. Quite historic, really.

Jim Morris: Meteorologist Kai Tawa of Western Weather Group in Chico commenting on the positive start of the water year, building hope that the drought might be broken.

Kai Tawa: From there our luck really continued going into December with some more atmospheric river storms with things looking good.

Jim Morris: Unfortunately, 2022 has been underwhelming for rain and snow.

Kai Tawa: We know it was certainly one of the driest January's recorded throughout northern California, and now we're going into February here. The medium to long-range models are pretty confident that we're going to remain quite dry.

Jim Morris: Today, we take a look at California's water shortage and how long-term planning can help the state survive and thrive.

Jim Morris: Welcome to Ingrained, the California rice podcast. I'm your host, Jim Morris. Proud to have worked with California farmers and ranchers for the past 32 years to help tell their stories. As if the pandemic wasn't enough, this year has started with little rain and snow fueling concerns that once winter is all over we may be in another dry year. That would be painful for our environment, cities, and farms. It's been more than 40 years since the last major water storage facility has been built in our state and our population nearly doubled over that time. Many are eyeing Sites Reservoir as a big part of a more stable water future. Proposed for the west of the Sacramento Valley in Colusa and Glenn counties, Sites would provide a major boost to the amount of water that can be stored during wet years to help during the dry ones. Jerry Brown is general manager of the Sites project authority, and Jerry, it would be good to get caught up on how the project is proceeding. I understand there's important news from the California Water Commission, so can you tell us a little bit about some of the latest developments with the Sites project.

Jerry Brown: Just last month, the state made a feasibility determination for the project, which they went through a very extensive review process of several elements of the project and came to the determination that the project continues to be feasible and investible from the state's perspective under the Prop 1 storage program. That compliments the earlier decision by the federal government for a similar feasibility determination, and between those two that represents anywhere from 30 to 40% of the project. Beyond those investors, there's the local agencies, and they are going through a process right now to evaluate their continued participation in the project, and we're getting really good and positive responses from the local agencies. Collectively we're looking really strong as far as where we are, and the funding levels to proceed with the project, and have a lot of momentum to move forward with some great work in the coming years.

Jim Morris: Those who are unfamiliar with Sites, this would be an off stream reservoir fed by excess water from rainstorms. Is that right?

Jerry Brown: That's right, Jim. Sites is not your old dam. It is a reservoir that is set off the Sacramento River, but does receive water diverted out of the river, but only taken during the highest flow periods in the river, pretty much the very wet times like 2017, 2019 would be the timeframes, that would store the water in the reservoir during those periods until we need it in the drier times when we would release it back into the river for meeting demands of our participants or directly serving demands within the area of the reservoir. It's really an insurance policy for those drier times which we're seeing more often and more severely. It's something that we need in order to prepare ourselves for our future.

Jim Morris: Past years, we've certainly seen, we've had tremendous amounts of rainfall and we haven't been fully able to capture all of it. Is it feasible to think if we have an incredibly wet year, that Sites can fill rather rapidly?

Jerry Brown: If you look at averages and the analysis that we've done, we're expecting that we could fill the reservoir in anywhere from five to seven years. But from my experience in my prior life as the general manager of Contra Costa, we were able to fill Los Vaqueros on first spill in one year, and we had originally anticipated a five to seven year fill period as well. That's a question that a lot of people ask me is how long is it going to take to fill, and it couldn't be anywhere from one year to, on average, five to seven years.

Jim Morris: The environment is talked about a lot in California and for good reason, it's vital, of course. The diminished salmon runs come up a lot, and at the rice commission, we're working with UC Davis on a pilot project raising salmon and rice fields. There's also promising work where fish food is being produced in rice fields and then returned to the river to help salmon. Jerry, what would Sites do to help this area?

Jerry Brown: There's two aspects to Sites that I think need to be understood. First, the state is an investor in the project, and as such, they are receiving benefits for the environment. There will be a dedicated storage space and amount of water that is provided for the state to manage for the benefit of the environment, including the salmon, and including the delta smell, for example, is another species that could be helped with the project. What they will be able to do is storing this water in the wet years for use in the dry years. In these dry times like we've been seeing and the effects that we're seeing on the salmon, this water could help the salmon survive these periods, so that's number one. Number two, being where we are on the Sacramento River and where we are located relative to Shasta and Orville and Folsom Lake, there are opportunities to coordinate the site's operations in a manner that could provide for greater cold water in those reservoirs. Cold water can, especially in the dryer years, can enhance our abi
