Topic: Agricultural Drainage

Overview

Agricultural Drainage

California’s rich agricultural productivity comes with a price. The dry climate that provides the almost year-round growing season also can require heavily irrigated soils.  But such irrigation can also degrade the local water quality.

Two of the state’s most productive farming areas in particular, the west side of the San Joaquin Valley and parts of the Imperial Valley in southern California, have poorly drained and naturally saline soils.

Commentary: How a rich water district beat the federal government in a secret deal

Clout can be defined in many ways. In California’s parched Central Valley farmlands, it’s the ability to secure water. By that measure, the giant Westlands Water District has just set a whole new standard.

Salt of the Earth: Salinity in California’s Central Valley

Salt. In a small amount, it’s a gift from nature. But any doctor will tell you, if you take in too much salt, you’ll start to have health problems. The same negative effect is happening to land in the Central Valley. The problem scientists call “salinity” poses a growing threat to our food supply, our drinking water quality and our way of life. The problem of salt buildup and potential – but costly – solutions are highlighted in this 2008 public television documentary narrated by comedian Paul Rodriguez.

March/April 2006

This issue of Western Water examines that process. Much of the information is drawn from discussions that occurred at the November 2005 Selenium Summit sponsored by the Foundation and the California Department of Water Resources. At that summit, a variety of experts presented findings and the latest activities from areas where selenium is of primary interest.

Layperson’s Guide to Agricultural Drainage
Updated 2001

With irrigation projects that import water, farmers have transformed millions of acres of land into highly productive fields and orchards. But the dry climate that provides an almost year-round farming season can hasten salt build up in soils. The build-up of salts in poorly drained soils can decrease crop productivity, and there are links between drainage water from irrigated fields and harmful impacts on fish and wildlife.

Water on the Edge (60-minute VHS)

Water truly has shaped California into the great state it is today. And if it is water that made California great, it’s the fight over – and with – water that also makes it so critically important. In efforts to remap California’s circulatory system, there have been some critical events that had a profound impact on California’s water history. These turning points not only forced a re-evaluation of water, but continue to impact the lives of every Californian. This 2005 PBS documentary offers a historical and current look at the major water issues that shaped the state we know today. Includes a 12-page viewer’s guide with background information, historic timeline and a teacher’s lesson.

Imperial Valley

Southern California’s Imperial Valley is home to California’s earliest agricultural drainage success story, one that converted a desert landscape to an agricultural one, but at the same time created far reaching consequences.

Image of Evaporation Ponds
Aquapedia background

Evaporation Ponds

Evaporation ponds contain agricultural drainage water and are used when agricultural growers do not have access to rivers for drainage disposal.

Drainage water is the only source of water in many of these ponds, resulting in extremely high concentrations of salts. Concentrations of other trace elements such as selenium are also elevated in evaporation basins, with a wide degree of variability among basins.

Such ponds resemble wetland areas that birds use for nesting and feeding grounds and may pose risks to waterfowl and shorebirds.

Agricultural Drainage Environmental Impacts

Agriculture drainage issues date back to the earliest farming. In ancient times, farmers let fields stay fallow hoping rain would flush out salt.

Today, salt and other contaminants continue to cause agricultural drainage problems, particularly in California. Whether a field is adequately drained, or saturated with water, the water still has to be removed.

The disposal of this often-contaminated water continues to be a challenge in California, with the environmental effects of selenium and other drainage-related elements changing the course of drainage planning.
