No one has a crystal ball to foresee what will happen during the 2018 hurricane season that begins June 1, but NOAA forecasters say there’s a 75 percent chance this hurricane season will be at least as busy as a normal year, or busier.
Crews from the U.S. Geological Survey have been in the field for weeks measuring flooding in the Midwest and in the Mississippi River watershed, and more recently flooding and storm tides on the Northern Atlantic coast, as higher temperatures, heavy rain, snowmelt and nor’easters affected numerous states.

Lakes and reservoirs—Guidelines for study design and sampling
The “National Field Manual for the Collection of Water-Quality Data” (NFM) is an online report with separately published chapters that provides the protocols and guidelines by which U.S. Geological Survey personnel obtain the data used to assess the quality of the Nation’s surface-water and groundwater resources. Chapter A10 reviews limnological...
Putting flow-ecology relationships into practice: A decision-support system to assess fish community response to water-management scenarios
This paper presents a conceptual framework to operationalize flow–ecology relationships into decision-support systems of practical use to water-resource managers, who are commonly tasked with balancing multiple competing socioeconomic and environmental priorities. We illustrate this framework with a case study, whereby fish community responses to...Cartwright, Jennifer M.; Caldwell, Casey; Nebiker, Steven; Knight, Rodney
Water resources of the Southern Hills regional aquifer system, southeastern Louisiana
Information concerning the availability, use, and quality of groundwater in the 10 parishes overlying the Southern Hills regional aquifer system of Louisiana (fig. 1) is critical for water-supply management. The purpose of this fact sheet is to present information that can be used by water managers, residents, and others for stewardship of this...White, Vincent E.
