The U.S. Geological Survey (USGS) South Atlantic Water Science Center streamgage program is part of the nationwide program that provides streamflow information for a variety of purposes—including the protection of life and property, infrastructure design, recreational usage, and long-term trend assessment. This information is critical to resource managers, farmers, fishermen, kayakers, land-use...

As Hurricane Matthew moved up the Atlantic coast of the U.S., the USGS South Atlantic Water Science Center (SAWSC) deployed most of the USGS Storm-Tide Network along the Atlantic coast to monitor the timing, extent, and magnitude of the storm tide during the passage of Hurricane Matthew.

Many days of continuous heavy rain in mid-September 2009 resulted in flooding in many parts of Georgia, especially in north Georgia and the Atlanta region. The rains produced streamflows of record proportions. rivers and streams had magnitudes so great that the odds of it happening were less than 0.2 percent in any given year. In other words, there was less than a 1 in 500 chance that parts of...

Current and Historical Peak Stage Bar Graphs for North Carolina The Peak Stage Bar Graphs section for North Carolina allows you to compare current stream stage with historic peaks at water-monitoring sites throughout North Carolina.

Reliable estimates of the magnitude and frequency of floods are essential for such things as the design of transportation and water-conveyance structures, flood insurance studies, and flood-plain management. Flood-frequency estimates are particularly important in densely populated urban areas. The U.S. Geological Survey (USGS) is using a multistate approach to update methods for determining the...

Peachtree Creek WaterWatch, Atlanta, GA Peachtree Creek is a major tributary to the Chattahoochee River in Atlanta, GA.
