©Nathan Weyland, Children pose for a picture in front of a mobile aquarium during the 2009 Salmon Festival at the Feather River Fish Hatchery in Oroville, CA. Species such as salmon and steelhead have become symbols of the environmental and conservation movements, which are in turn mocked by the agricultural industries through slogans such as “fry a fish, feed a farmer.”

Victorian and his colleague (not pictured) were living off the grid in May 2009 for lack of work. Average documented unemployment in the region was 36.5 percent, primarily due to lack of water and the subsequent layoffs of labor in farm and other industries, according to a report by the Fresno County department of public health. May 20, 2009.

©Nathan Weyland, Sport fisherman are up early for the brief salmon season on the Sacramento River. The commercial Salmon fisheries were completely closed in 2008 and 2009, and the sport fishing season lasted just 2 weeks in 2009 due to badly depleted salmon runs.

©Nathan Weyland, Employees of the Feather River Fish Hatchery wait for a holding tank to be filled with fish before beginning salmon spawning operations. Due to the decline in fish stocks, hatcheries do nature’s work by killing, harvesting and incubating eggs until the fish are hatched and large enough to be released to the wild. Studies have shown significant biological and behavioral differences between wild fish and hatchery fish.

Curtis Howard unloads Ferrous Chloride, used in the chemical treatment process of the primary plant.

©Nathan Weyland, Zach Wenderott, 29, and Laura Lalemand, 36, are biological technicians with the United States Geological Survey’s Redwood Field Station in Arcata, CA. They both work with USGS field ecologist Philip van Mantgem, who is conducting a long-term study of tree mortality and demographics throughout the West. A goal of the project is to learn how to better manage forests for tree health.

Sutter county is known for stone fruit, rice and almonds. Nearly all the plums produced in the United States come from this region of California.

©Nathan Weyland, Pedro Garcia moves siphon tubes to flood irrigate a field of alfalfa near Discovery Bay, in the San Joaquin Delta, on April 29, 2009. Flood irrigation is the least-efficient method of irrigating, in terms of both water consumption and crop yield.

©Nathan Weyland, Robert Weimer is farmer in Merced County near Atwater, CA. He primarily grows almonds, sweet potatoes and peaches. Bob, as he is generally known, has made significant investments in water efficiency over the years, and applies scientific rigor throughout his operation. The sole source for above-ground water in his area is Lake McClure, which is perilously low. Historically, the region has primarily relied on groundwater. Now that is more the case than ever.
