Groundwater Administrative Areas / Critical Groundwater Areas

There are 22 designated groundwater administrative areas around the state with differing levels of restriction.  These include critical groundwater areas (CGWAs), groundwater limited/classified areas, and areas withdrawn from further appropriation.  Some areas have time-limited permit restrictions for uses requiring water rights.  Other areas are closed to new appropriations or have well construction requirements to protect senior water rights.  Staff monitor these areas to ensure that the restrictions adequately protect the groundwater resource and existing users.

Department hydrogeologists also provide technical input for mitigation opportunities in the Deschutes, Grande Ronde, and Klamath Basins to protect scenic waterways and instream flows.  The mitigation program in the Deschutes Basin is designed to allow development of groundwater using mitigation credits to maintain or improve streamflow.
