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.

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 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.
