We wish to make the bittersweet announcement that Jonathan Dillow has retired.

Jon started his USGS career in 1992 as a hydraulic engineer, working on numerous surface water and groundwater studies before becoming the supervisor of the Surface Water Section and the Center’s Data Chief.

Jon most recently served as the Center’s Surface Water Specialist. In addition to his technical expertise, he showed exceptional supervisory and mentoring leadership in his roles as supervisor, associate director, and acting Deputy Director.

Some of Jon's many scientific achievements included completing statistical hydrology studies for Maryland and Delaware, groundwater/surface water/water quality of the Maryland coastal bays, synoptic sampling and groundwater optimization modeling, and stream restoration studies at Minebank Run.

Jon has also worked on all aspects of the stream gage network, including construction, field trips, flood measurements, records computation, review and approval of data, flagging high water marks, and indirect computation and reviews.

In addition to his scientific work, Jon was an invaluable coach and mentor to other supervisors and employees in the Center. He helped numerous employees find successful paths for their careers and served as a mentor to new supervisors through the Office of Employee Development.

In these various roles, Jon represented the USGS to many partners in Maryland, Delaware, and the District of Columbia, as well as to numerous Federal colleagues, many of whom sought out his advice on surface water and groundwater problems and challenges.

His service as an Associate Director in the Maryland-Delaware-D.C. Water Science Center was instrumental in significant improvements in the Center’s workforce plan and work processes. His leadership and mentoring left a positive mark on the USGS that will last for many years to come.

We wish Jon the very best in his next adventure!
