Molly Wood is the Chief of the USGS Water Resources Mission Area’s Hydrologic Networks Branch.
Molly is a Senior Hydrologist and Branch Chief for the USGS’ Water Resources Mission Area Headquarters. She has an educational background in Civil and Environmental Engineering and has worked in both the private consulting and federal government sectors. She helps set national policies for water resources monitoring, advises on funding priorities, provides expert advice and training, and develops innovative water monitoring techniques to inform water resource management decisions. Previous USGS roles include serving as a Hydrologist for the Florida Integrated Science Center working on the Comprehensive Everglades Restoration Plan, a Hydrologist and Surface Water Specialist for the Idaho Water Science Center, the National Sediment Specialist for the Water Resources Mission Area, and the acting Chief of the USGS Office of International Programs’ Branch of International Science Collaboration. She has provided technical assistance with hydrologic data collection and research to government agencies and organizations across the world..
Science and Products
Assessing River Erosion and Sedimentation in Ecuador
In cooperation with the U.S. Army Corps of Engineers, USGS is helping Ecuadorian government officials from the Electric Corporation of Ecuador (CELEC) develop strategies for managing sediment and erosion in the Río Coca basin after the 2020 collapse of the 144-meter-tall San Rafael waterfall.
Next Generation Water Observing System (NGWOS)
Substantial advances in water science, together with emerging breakthroughs in technical and computational capabilities, have led the USGS to develop a Next Generation Water Observing System (NGWOS). The USGS NGWOS will provide real-time data on water quantity and quality in more affordable and rapid ways than previously possible, and in more locations.
Sediment Laboratories
The USGS maintains sediment laboratories in several Water Science Centers and offices across the country.
Sediment Surrogate Techniques
USGS develops and uses “surrogate” techniques to estimate sediment at times when it can’t be physically measured through samples.
Sediment Sampling and Data Processing
USGS collects sediment samples at thousands of locations across the U.S. using nationally consistent methods.
Sediment Acoustics
The U.S. Geological Survey recognizes the need to provide sediment acoustic training and to develop standardized techniques and practices.
Sound Sediment Science
A training course to augment USGS Course H-17-037, Acoustic Index Method for Estimating Fluvial Suspended Sediment and USGS Techniques and Methods Report 3C-5
Fluvial Sediment and Geomorphology: Resources for Monitoring and Analysis
The USGS collects fluvial sediment and geomorphic data and conducts related research at numerous sites across the Nation. This information is essential to informed solutions to sediment-related and overall water resource management issues.
Groundwater and Streamflow Information Program
The Groundwater and Streamflow Information Program serves as the national source of impartial, timely, quality-assured, and relevant water data for short- and long-term water decisions by local, State, tribal, regional, and national stakeholders. Our objectives are to collect, manage, and disseminate consistently high-quality and reliable hydrologic information in real-time and over the long-term.

Kootenai River Habitat Restoration
Constructed channel features and changes in the Phase 1A side channel restoration area of the Kootenai River near Bonners Ferry, Idaho. The Kootenai Tribe of Idaho is managing a large-scale, ecosystem-based river habitat restoration effort that will be implemented over a period of 10 to 15 years across a 55-mile reach of the Kootenai River in northern Idaho.

Acoustic Doppler Velocity Meter
An acoustic Doppler velocity meter mounted on a track for instream deployment. The USGS deployed devices similar to this on at three monitoring sites on northern Idaho's Kootenai River to estimate sediment concentrations in the spawning habitat of the endangered Kootenai River white sturgeon.
