Bill Swenson, right, and Jeff Goetz, both hydrologic technicians for the U.S. Geological Survey, test the water speed to calculate the discharge measurement of the Mendenhall River using a bridge crane Thursday on Back Loop Road. The group checks the flow of different areas every couple of months to calibrate the equipment. Goetz says a real-time water level display for the Mendenhall and other rivers can be found on www.usgs.gov.
