In 1990, the USGS began assessing water-quality in the Tualatin River. Almost 30 years later, we are still monitoring conditions in the basin.
The USGS began to assess water quality conditions in the Tualatin River in 1990. The research included tracking how nutrients entered the river and establishing a instrument network to monitor dissolved-oxygen concentrations. Eventually, more issues arose and the research expanded to meet the needs of those reglatory agencies that manage the natural resources of the basin.
