Integrated Water Resources Planning

In June 2016 the Harney County Watershed Council was awarded a grant to undertake place-based integrated water resources planning in partnership with the Oregon Water Resources Department. This is a locally led collaborative process co-convened by the Harney County Watershed Council and the Harney County Court.

Groundwater Study

OWRD is expanding its data collection efforts in the Malheur Lake Basin, specifically in and around the Greater Harney Valley Area, because of concern for declining groundwater levels. Part of OWRD's mission is to ensure sufficient water supplies for current and future needs. Over the next five yearOWRD is partnering with the US Geological Society to complete a comprehensive groundwater study to better understand groundwater resources in the Greater Harney Valley.

In June 2016 OWRD and the Harney County Court solicited letters of interest and appointed individuals to a Groundwater Study Advisory Committee. Click here​ for the Charter, which includes a list of the Advisory Committee members.

Basin Program Rules

The Basin Program describes how water in Malheur Lake Basin may be used. The original rules were adopted in 1990. Modifications to the rules were adopted in 2016. A summary of the original rules and updates are provided in the table below.

 
Year​ ​Summary ​​Link
​2016 Establishes the Greater Ha​rney Valley Groundwater Area of Concern. Provides flexibility f​or addressing pending ​groundwater applications while OWRD is conducting a ​five-year groundwater study. Link​
​1990 ​Describes that new uses may only be allowed if water is available. Exceptions include uses for an instream right, a permit to store water between March 1 and May 31, use of stored water or a multi-purpose storage project authorized under OAR-690-512-0100. The Malheur Lake Basin Program also establishes minimum stream flows and reserves water for future economic development in the Home Creek sub-basin.
