Episode 20: Moving Forward in a Dry Year

Tractors are working ground in the Sacramento Valley, as the 2021 rice season is underway.

Whether it's farmers, those in cities or for the environment, this year will pose challenges due to less than ideal rain and snowfall during the fall and winter.

At Montna Farms near Yuba City, Vice President of Operations Jon Munger said they expect to plant about one-third less rice this year, based on water cutbacks. As water is always a precious resource in this state, rice growers work hard to be as efficient as they can. Fields are precisely leveled and will be flooded with just five-inches of water during the growing season. Rice is grown in heavy clay soils, which act like a bathtub to hold water in place. High-tech planting and harvest equipment also help California rice farms and mills operate at peak efficiency.

Expectations of less rice acreage will impact other parts of the valley – rural communities, allied businesses and the environment – birds and fish.

"The Central Valley is arguably one of the most important waterfowl areas on the planet," remarked Jeff McCreary, Director of Operations for Ducks Unlimited's Western Region. "It's because of all of these birds coming down the Pacific Flyway… and when we think about the drought, it's going to affect that wintering habitat. Is there rice on the landscape? Is there water for wetlands? How do we make sure that those populations are in as good enough condition that when they go back to the breeding ground, they can have a successful year."

McCreary said rice fields are critically important for wintering waterfowl, supporting 60 percent of the food energetics these birds need.  He said of all of the duck species, the Mallard is perhaps the most impacted by dry weather in California.

Another environmental concern during dry weather is the wild salmon population, which faces significant challenges.  However, farmers, water districts, conservationists and others are working hard to find solutions.

"The salmon rice work is among the most exciting work I've ever been a part of, "said Andrew Rypel, an associate professor and the Peter B. Moyle and California Trout Chair in Coldwater Fish Ecology at UC Davis in the Department of Wildlife, Fish & Conservation Biology. Rypel is one of the key participants in pilot salmon research, including raising juvenile salmon in winter rice fields, then releasing the fish into the ocean. So far, results with the project have been very positive.

Another key project to help salmon is putting a shallow amount of water on rice fields in the Sacramento Valley after harvest, which creates "fish food"- zooplankton – which is then released into the river to help feed wild salmon runs.

Water managers always have a balancing act to meet the needs of their customers, and dry years provide even more careful consideration.  Lewis Bair, General Manager of Reclamation District 108 in the Sacramento Valley, is one of those navigating through this dry year, which includes creative approaches with water, including the likelihood of transfers.

"In a dry year, our folks would still love to farm, just like they always love to farm," he said. "But in these types of years, we end up kind of sharing the pain by doing water transfers. Sometimes, it's better to move water around for the whole system. You end up being able to achieve other benefits. It really is a short-term solution. We need to have a more reliable water supply for California, and I'm hoping that the long-term vision and long-term investments will help reduce the need for those sorts of transfers."

Bair said building Sites Reservoir would be a major help to the state's water future, providing new storage and flexibility to re-operate the system for water use efficiency.

"I think it's the most promising thing we can do from an infrastructure perspective," he added. Munger, McCreary, Rypel and Bair all have different responsibilities, but they share a common goal- to help our region withstand dry years, including a healthy ecosystem and sufficient water for cities and farms. They all agree that the level of cooperation is great in the Sacramento Valley, as evidenced by the scores of voluntary, collaborative projects that have been done to help maintain the Pacific Flyway and enhance the wild salmon runs.
