Jonathan Haynes
Jonathan Haynes is a hydrologist at the USGS Oregon Water Science Center.
Jon started with the USGS in 1999, investigating groundwater and water use for the New Mexico Water Science Center. In 2002, he joined the Oregon Water Science Center where he has focused on water use, water availability, GIS, and total-dissolved gas. Jon is the Oregon Water-Use Specialist.
Science and Products
Sources and characteristics of dissolved organic carbon in the McKenzie River, Oregon, related to the formation of disinfection by-products in treated drinking water
Hydrologic budget of the Harney Basin groundwater system, southeastern Oregon
Groundwater-level declines and limited quantitative knowledge of the groundwater-flow system in the Harney Basin prompted a cooperative study between the U.S. Geological Survey and the Oregon Water Resources Department to evaluate the groundwater-flow system and budget. This report provides a hydrologic budget of the Harney Basin groundwater system that includes separate groundwater budgets for up
