A U.S. Geological Survey hydrologist holds a centrifuge bowl containing river suspended sediment for analysis of metals and organic chemicals. The sample was collected using a new in-field continuous-flow centrifugation technique to separate and collect suspended sediment from large volumes of water.

A U.S. Geological Survey streamflow gaging station collects water data on the Trask River. The Trask River gage is located near Tillamook, Ore. and has been in operation for 17 years.  

Trask River stage, discharge, and water-quality data are collected and used together to help monitor the current health of the river. Data from the river are sent to equipment in the gage house, where it is stored then transmitted to USGS servers.
