Big data for small streams: Leveraging a coarse national model to enhance fine-resolution stream temperature predictions Big data for small streams: Leveraging a coarse national model to enhance fine-resolution stream temperature predictions
Predictive stream temperature models are commonly used to address spatial and temporal gaps in observational data because stream temperature information is essential for environmental management decisions. National models capture broad patterns driven by climate, topography, and seasonality, but often lack the spatial resolution to simulate fine-scale variation in groundwater discharge...
A spatial analysis of the groundwater emergence flood hazard in Long Island, New York, and coastal areas surrounding Long Island Sound in New York, Connecticut, and Rhode Island A spatial analysis of the groundwater emergence flood hazard in Long Island, New York, and coastal areas surrounding Long Island Sound in New York, Connecticut, and Rhode Island
Long Island, New York, and nearby coastal areas surrounding Long Island Sound are densely populated and, like other coastal areas, are susceptible to flooding from several potential sources, including stormwater from precipitation events, tidal flooding and storm surge, and groundwater emergence flooding. Groundwater emergence fooding refers to the intersection of a rising water table...

Lake Champlain Basin Research
The USGS works in collaboration with Federal, tribal, state, university, Canadian Provincial, and non-government organizations on research and monitoring efforts in the Lake Champlain Basin. For many years, the USGS has produced water quality, hydrologic, and ecological data and science to support the management of the lake and watershed through increased scientific understanding.
A Culvert Sizing Tool for Vermont StreamStats
Vermont currently (2025) manages nearly 15,000 culverts, many of which are undersized and classified as being in urgent, critical, or poor condition. After large flooding events, stream crossing structures are frequently replaced in kind with little ability to integrate best available topography and design flows. The USGS, in cooperation with Vermont Agency of Transportation (VTrans), is updating...
Low-Streamflow Statistics for Unregulated Streams in Vermont
Below normal streamflows can intensify competing water demands and affect water quality, drinking-water supplies, and aquatic habitat. Estimating normal low-flow statistics is critical to support natural resource management. The current methods for estimating low-flow statistics at ungaged streams, particularly on small watersheds, are limited in Vermont. The USGS is computing low-flow statistics...
