Crater Lake inspires awe. Native Americans witnessed its formation 7,700 years ago, when a violent eruption triggered the collapse of a tall peak. Scientists marvel at its purity—fed by rain and snow, it’s the deepest lake in the USA and one of the most pristine on Earth.

This is a view of a USGS surface water stream gage that contains equipment to monitor discharge at the Williamson River below the Sprague Ruver in Chiloquin, Oregon. The gage house contains a historic stilling well and a device that records the level of water. It also has a water temerature sensor and a turbidimeter.

While surveying high water marks in Oakridge, Oregon, bumble bees buzzed around the river banks. The bees often mistake our bright colored equipment and florescent safety gear for tasty yellow flowers.

The gage house is sitting on a circular metal base also known as a stilling well. Stilling wells fill with calm water that is equal to the height of the river that is read by sensors inside. This technique has been in use for decades to collect water level data.

Malheur Lake is shown with turbid water and without emergent vegetation. Snowpack from Steens Mountain (shown in the distance) provides most of the inflow to Malheur Lake.
