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).

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.

Sometimes equipment can only be accessed by diving to it!

The brown PVC bank mounted pipe houses water-quality instruments. The grey cylinder houses an automatic sampler, that draws water samples from the river at programed times.

Lisa Hoaks and Carrie Boudreau ran an exhibit booth at the 2024 Children's Clean Water Festival. They presented an introduction to the Water Cycle with an interactive matching game along with a look at the USGS Streamer app to see where nearby rivers flow.
