About 5 million waterfowl spend the winter on state and federal wildlife refuge areas and flooded rice fields in the Central Valley each winter.

“This year, the worst drought in a generation means those Central Valley habitats have been dramatically reduced in size. Wildlife refuges have had their state and federal water supplies cut by 25 percent. Rice acreage has been reduced by a similar amount as farmers also have endured water cutbacks.
