A USGS field technician enjoyed a sighting of a Blue Heron while inspecting water-quality gage equipment on the Tualatin River at the Oswego Dam site (14207200).

Sometimes equipment can only be accessed by diving to it!

View from a metal platform looking down into the Willamette River. Technicians use a freshly calibrated "reference monitor" to verify site monitor readings. Here, a reference monitor hangs from the platform into the water.
