LINCOLN, Neb. (AP) — Nebraska’s system for managing its groundwater is catching the eye of other states that are running dry and threatening farmers with water restrictions.

Despite its widespread use for crop irrigation, Nebraska’s groundwater supply has remained stable while states such as California and Texas struggle with shortages. The difference has led some out-of-state groups to inquire about how Nebraska uses 23 natural resources districts to manage groundwater while the Department of Natural Resources oversees rivers and lakes.

Dean Edson, of the Nebraska Association of Resources Districts, says he’s received inquiries from half a dozen states and is scheduled to speak about Nebraska’s system in California next month.

Jim Schneider, acting director of the Nebraska Department of Natural Resources, will discuss the state’s groundwater management system before a national group in November.
