Rising floodwaters overtopping a local bridge. Charlotte-Mecklenburg Hydrologic Network
July 6, 2017

The U.S. Geological Survey (USGS) has been collecting streamflow data in North Carolina for more than 100 years. In the Charlotte and Mecklenburg County area, a hydrologic data-collection network has been established to collect not only streamflow data but also rainfall data. In response to the floods of August 1995 and July 1997, the U.S. Geological Survey Cooperative Water Program and Charlotte-Mecklenburg Stormwater Services has expanded and enhanced this data-collection network.

Currently, the network consists of 72 raingages and 54 streamgages. It has grown over the last 20 years and evolved from a two-way polling landline system to a true real-time notification system using line-of-site radios and satellite telemetry.

Acoustic Doppler current profiler (ADCP) is connected to an onboard computer to measure streamflow.
June 1, 2017

In the mid-1990s, a new technology emerged in the field of inland streamflow monitoring. The South Atlantic Water Science Center is making great use of the acoustic Doppler current profiler (ADCP). It was originally developed for oceanographic work, but was adapted for inland streamflow measurements. This instrument is transforming the U.S. Geological Survey (USGS) streamgaging program.

Measuring streamflow, Georgia
May 9, 2017

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.

The multiyear drought in North and South Carolina (summer 1998-fall 2002) brought wide recognition of the vulnerability of the water resources in these two States to climatic conditions. To prepare for drought conditions in the future, water managers and State and Federal water-resource agencies sought to develop tools to assess hydrologic conditions in both a predictive and responsive manner. USGS partnered with the Catawba-Wateree Water Management Group to establish a monitoring network of near real-time streamflow gages (surface-water stage/discharge) and wells (groundwater levels), which are the essential components for assessing hydrologic conditions.

“USGS long-term streamgages and groundwater wells are like a fine wine…they get better with age!”

The accurate, long-term monitoring networks of SAWSC provide valuable data in real-time and historical perspective to compare that data to.  The longer a monitoring location is in operation, the more valuable it becomes, since more statistical comparisons can be performed.  Our field technicians continuously make field measurements  and maintain these networks.

USGS WaterNow: Example of output message on a smartphone.
February 6, 2017

USGS WaterAlert allows users to set notification thresholds for any USGS real-time stream or raingage, water-quality, or groundwater monitoring site and then sends emails or text messages to subscribers whenever the threshold conditions are met, as often as every hour.

USGS WaterNow allows you to send a text message or email containing a USGS current-conditions gaging site number and quickly receive a reply with its most recent observation(s).

Real-time precipitation networks for Georgia and North Carolina
February 5, 2017

We now have a map and data table-based system to allow you to view real-time precipitation at Georgia and North Carolina water-monitoring sites. The rainfall maps and tables are updated continuously and display data from the last 1-3 hours up to 7-28 days.

SW Georgia Agricultural Water Conservation and Metering Program
February 3, 2017

During 2008-2015, the U.S. Geological Survey investigated methods to estimate agricultural water use and growing season pumping rates through the analysis of water-meter data throughout southwest Georgia. Reports are available by year.

StreamStats - Water-monitoring site analysis from USGS
February 1, 2017

StreamStats is a map based Web application that provides information that can be used by engineers, managers, and planners to make informed decisions on water-related activities. Primary products are basin delineations, basin-characteristic measurements, and estimates of streamflow statistics. StreamStats allows for the analysis of upstream and downstream relations along streams.

Sanford sub-basin, and other Early Mesozoic (Triassic) Basins in North Carolina
January 20, 2017

The U.S. Geological Survey (USGS) South Atlantic Water Science Center is conducted an inventory of well records and baseline groundwater-quality sampling to better delineate areas of groundwater use and groundwater-quality characteristics prior to potential shale gas exploration in the Triassic Basins of Lee and Chatham Counties, North Carolina. The compilation of baseline groundwater-quality data in North Carolina provided an opportunity for comparison to data collected after drilling activities commence should shale gas exploration be allowed to occur.

Moore County, NC Groundwater-Level Monitoring Map
January 18, 2017

An increasing demand for drinking water is one of the major issues facing the Moore County area. Managers need accurate information on surface and groundwater conditions to plan and balance maintaining an adequate water-supply and meeting in-stream flow requirements. The principal study objective is to collect water-level data at existing monitoring wells to establish a long-term data set that can be used to monitor changes in water levels and to aid in the future management of the county's groundwater resources.
