Lower Umatilla Basin Groundwater Management Area (LUBGWMA)

The Lower Umatilla Basin Groundwater Management Area, or LUBGWMA, is about 550 square miles in northern Morrow and northwestern Umatilla counties. The Oregon Department of Environmental Quality designated it a groundwater management area in 1990 because of high levels of nitrate contamination in the groundwater. The LUBGWMA is a focal point for efforts to address elevated nitrate levels that threaten drinking water supplies, local ecosystems, and public health.
