Buying Land in Harney County, Oregon

Oregon's largest county, and one of its emptiest

Harney County covers more than 10,000 square miles -- the largest county by land area in Oregon -- yet is home to only about 7,300 residents, most of them in Burns (the county seat) and neighboring Hines. The rest of the county is dominated by high-desert rangeland, much of it federally managed: Bureau of Land Management grazing land across the sagebrush steppe, the Malheur National Wildlife Refuge roughly 30 miles south of Burns (created in 1908 and nationally known for the 41-day armed occupation of its headquarters in early 2016), and national forest along the edges of Steens Mountain and the Blue Mountains. For a land buyer, the practical implication is that genuinely private, buildable acreage represents a relatively small fraction of the county's enormous footprint, and adjacency to public land -- with its own access, grazing-permit, and boundary considerations -- is the norm rather than the exception.

A major, current groundwater crisis: the Harney Valley Critical Groundwater Area

The single most important recent land-use development in Harney County is water, not zoning. Since roughly 2010, the Oregon Water Resources Department has warned that groundwater pumping in the Greater Harney Valley -- overwhelmingly for irrigating alfalfa and other crops -- was drawing down the aquifer faster than it could recharge. In the Weaver Springs area about 20 miles southwest of Burns, groundwater levels have fallen by as much as 100 feet since the early 1990s and continue dropping 8 to 10 feet per year. The consequences have reached private domestic wells directly: OWRD has logged 16 new dry-well reports since 2022 among the county's roughly 2,000 domestic wells. In December 2025, the Oregon Water Resources Commission responded by formally designating the Greater Harney Valley a Critical Groundwater Area, a status that gives the agency authority to cap or reduce pumping and restrict new groundwater permits -- OWRD's draft rules propose a roughly 35% reduction in basin-wide groundwater pumping, with implementation beginning in 2028.

The state has paired this designation with a support program -- the Greater Harney Valley Well Fund -- intended to help replace, repair, or deepen domestic wells affected by the decline. For anyone evaluating land in the affected basin, whether for a homestead well or irrigated farm ground, this is not a hypothetical regulatory risk but an active, dated process with real near-term consequences. See the dedicated well-water page below for what the Critical Groundwater Area designation means for permitting a new well specifically.

EFU ranch zoning on the private land base

The private land that exists in Harney County -- concentrated around the Harney and Malheur Lake basins and along the Silvies River -- is predominantly zoned Exclusive Farm Use (EFU) under Oregon's statewide Goal 3 agricultural framework, supporting cattle ranching and the same alfalfa and hay irrigation described above. New-dwelling eligibility follows Oregon's general EFU tests (established farm income, qualifying lot-of-record status, or another narrow statutory exception), administered locally by Harney County Planning. Given the water situation described above, confirming both zoning eligibility and current water-availability status for any specific parcel is especially important here relative to most other Oregon counties.
