Timothy D Oden

Tim Oden leads the USGS hydrologic monitoring program that provides real-time water resource data for the Commonwealth of Pennsylvania at over 350 streamgages, 74 groundwater wells, 135 water-quality and 92 precipitation stations. 


Tim previously served the Water Mission Area (WMA) in the Observing Systems Division, Hydrologic Networks Branch where he led the Field Support Team and was program coordinator for the USGS-National Park Service Water Quality Partnership. Tim oversaw delivery of multi-disciplinary expertise in sediment, surface water, and discrete water quality, and worked on per- and polyfluoroalkyl substance (PFAS) field sampling methods and the national stream temperature network.

Tim also has worked on a detail for the Laboratory Analytical Services Division as a supervisor in the Quality Assurance Section, within the USGS National Water Quality Lab. His technical efforts have included conducting tests to better understand and test field methods, including the testing of self-contained dissolved oxygen sensors, working on testing of new gloves, and a national assessment of low-level ammonia in field blanks.

Tim is an active participant in the National Water Quality Monitoring Council, serving as the co-chair of the planning committee for the spring 2021 virtual National Monitoring Conference. He sits on the Continuous Water Quality Committee for the WMA regarding all aspects of the development and use of water quality sensors in support of extended deployments for continuous monitoring. He is an instructor at the USGS National Training Center for the Field Water Quality Methods for Surface-Water and Groundwater and Field Methods Refresher classes.

From 2013-2017 Tim was the Water-Quality Specialist for the USGS Central Region as part of the WMA’s Water Science Field Team and in that position was involved in the development of national water quality policy. From 2002 to 2013, Tim was  a project chief Hydrologist and then Water-Quality Specialist (2008) in the USGS Texas Water Science Center. He began his career with the USGS in the New Jersey Water Science Center in 1994 as a National Association of Geoscience Teachers (NAGT/USGS) intern.
