Water-Quality Sampling

Noses Creek at Powder Springs Road, Georgia. Part of the USGS safety protocol is to wear a PFD (personal flotation device) around any surface water. This scientist may not look like he has one on, but he does--it is under his rain coat. This DH-81 sampler is used to sample flood water for suspended-sediment concentrations and water quality.

Preparing Water-Quality Sampling Device for Use

A USGS scientist about the collect a water sample with a DH-95 sampler (the white torpedo looking device). After sampling, another scientist takes the bottle of water and pours it into the churn. Having another scientist do this prevents contamination of the sample.

Measuring Streamflow Through a Weir

Pew Creek below Johnson Road, Lawrenceville, Ga. The metal structure is a "V" weir. A sediment dam was built on either side of it to force the water through the weir. Scientists can calculate gallons per minute flow in the stream by timing how long the flow took to fill a bucket.

Test Well, East River

USGS test well 10 34h363 in the East River, Brunswick, Ga. The U.S. Geological Survey drilled this test well in the early 1970's and at the time it was on the edge of the marsh at Andrews Island. It is now only accessible by boat or canoe at high tide. Despite being surrounded by saltwater the artesian well flows very fresh water from the Upper Floridan Aquifer.

Installing Water-Level Monitoring Gage

Installing a water-level monitoring gage, Coosawattee River, Georgia. Two USGS workers installing a "stilling well"s, which is a major component of most systems used to monitor stream stage (gage height). The pipe is placed vertically into the stream and the level of the water in the pipe is continuously monitored and transmitted to USGS water-science offices.

Peachtree Creek, Atlanta, Ga. Debris from floods cause bridge problems

Peachtree Creek at Atlanta (USGS 02336300) Water Monitoring Site

Floods are powerful natural mechanisms that can move large amounts of debris seemingly easily. This picture shows the upstream side of a major highway bridge crossing Peachtree Creek in Atlanta, Ga. Looks like flood-borne trees and other debris that have gotten stuck on bridge
