Citrus farmers in the southeast corner of Louisiana are scrambling to find ways to irrigate their crops with fresh water

BATON ROUGE, La. — Commercial citrus growers have dwindled over the past few decades in south Louisiana, where farmers have had to battle hurricanes, flooding, invasive insects, freezes and drought to keep their groves alive.

The latest hurdle comes from a slow-moving threat — a mass influx of salt water from the Gulf of Mexico that is creeping up the drought-stricken Mississippi River. Not only is the saltwater intrusion threatening drinking water supplies for communities, but it can also kill citrus seedlings.

The issue is forcing farmers to brainstorm other ways to irrigate their crops with fresh water — including storing the little rain water they’ve gotten this summer, hauling in fresh water and establishing makeshift salination treatment facilities. Some are looking into whether they can afford, let alone get their hands on, an expensive reverse-osmosis machine.

“They’re going to have something up their sleeve. They know how to survive, but there’s no getting around how dire the situation is,” said Joey Breaux, the assistant commissioner of soil and water for the state’s agricultural department, about the farmers. “Unless they have another source of irrigation water, or a way to pretreat irrigation water, it doesn’t look too good.”

Many communities in south Louisiana rely on the Mississippi’s fresh water, with their intake facilities located along the river. Typically, the mighty flow of the Mississippi is enough to keep mass amounts of salt water from reaching too far inland. But hot and dry conditions across the country this summer triggered drought conditions that slowed the Mississippi’s
