Zach Woiak, watershed-management specialist contracted through Colorado State University to support the Directorate of Public Works Environmental Division Natural Resources Branch, conducts a water-and-stream survey Oct. 3, 2017, along Stillwell Creek on South Post at Fort McCoy, Wis. Four U.S. Geological Survey stream-monitoring stations are located at Fort McCoy. Data at monitoring stations is checked and the speed of the water flowing through the stream is measured. Also, a couple of the stations are equipped to take water samples and provide us with data on water quality. (U.S. Army Photo by Scott T. Sturkol, Public Affairs Office, Fort McCoy, Wis.)
