Jonathan Dillow
Biography
Jon Dillow is a Supervisory Hydrologist that oversees parts of the Studies Section in the Maryland-Delaware-District of Columbia Water Science Center and serves (half time) as the acting Data Chief for the Washington Water Science Center.
Research / Professional Focus / Current Projects
My duties encompass all aspects of USGS water-data collection, interpretation, and publication activities, but my particular areas of interest are workforce planning and staff development. Through these interests I work to maintain and support appropriate staffing levels and adequate skill sets to facilitate the effective and efficient performance of data analysis, interpretation and publishing tasks that are focused and aligned with the USGS mission and each Center’s water-science goals, and to ensure that each Center can meet its local and regional partners' water-resource data and analysis needs on a sustainable basis.

Science and Products
Next Generation Water Observing System: Delaware River Basin
The USGS Next Generation Water Observing System will provide high-fidelity, real-time data on water quantity and quality necessary to support modern water prediction and decision support systems for water emergencies and daily water operations. The Delaware River Basin pilot provides an opportunity to develop the NextGen observing system in a nationally important, complex interstate river...
MD-DE-DC WSC Water Use & Water Supply Capabilities
In Maryland, public supply water is delivered to users for domestic, commercial, and industrial purposes. Most is used for public services, such as public pools, parks, firefighting, water and wastewater treatment, and municipal buildings, and some is unaccounted for because of leaks, flushing, tower maintenance, and other system losses. 5.7 million Marylanders get their water from the public...
MD-DE-DC WSC GIS/Dataset Capabilities
Spatial analysts at the MD-DE-DC WSC use Geographic Information Systems to interpret data collected through field reconnaissance and downloaded from internal USGS, other federal, state, and local agencies, academic institutions, industry, and other professional contracting organizations. GIS is used to analyze the data using shapefiles and geodatabased information to help prove or disprove...
MD-DE-DC WSC Geomorphology and Sediment Studies Capabilities
Geomorphology is classified as the study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the Earth's surface. Adding water creates a whole new dynamic known as Fluvial Morphology. Rivers and streams act as conduits of water along with sediment. As water flows over the channel bed, it is able to...
MD-DE-DC WSC Laboratory Capabilities
The labs at the MD-DE-DC WSC are clean, well-stocked, and appointed with modern equipment and a highly talented staff. The three labs analyze samples, conduct controlled-environment chemical tests with GCMS in the Water Qualty lab. Scientists and technicians work with core samples and analyze soils in the Sediment Lab.
Our labs assure reliability, reproducibility, and high quality of...
MD-DE-DC WSC Water Quality Capabilities
Water quality is a measure of the suitability of water for a particular use based on selected physical, chemical, and biological characteristics. Water-quality monitoring is used to help water-resource managers understand and avert potential negative effects of man-made and natural stresses on water resources, evaluate trends, and compare to water-quality criteria.
One of our primary...
Coastal Monitoring Tide Gage Sites in Maryland, Delaware, and Washington, D.C.
Vital coastal storm-tide information needed to help guide storm response efforts following major storms affecting Maryland will be more accessible than ever due to a new monitoring network the U.S. Geological Survey is currently building.
A team from the USGS MD-DE-DC Water Science Center is surveying 63 locations in the state, determining their elevations and installing receiving...
MD-DE-DC WSC Capabilities Sites
There's a lot of talent at the Maryland, Delaware, Washington, DC Water Science Center!
We’ve created a series of websites, thematically named to characterize our work as our “Capabilities”, working interdependently with a diverse array of cooperative partners, the scientists, technicians, and support staff work tirelessly to produce the high-quality output for which...
