Summary

Water quality point measurements were collected by the U.S. Geological Survey along the lower Willamette River near the cities of Lake Oswego and Wilsonville, Oregon, as well as the lowest two kilometers of the Clackamas River, Molalla River, and Johnson Creek. These measurements were collected in the main channel and off-channel features on discreet dates from April through October of 2017. All measurements include location, time, temperature, and depth below water surface, while many also include specific conductance, dissolved oxygen, pH, and turbidity.

Purpose

These water quality measurements were collected in an effort to locate, identify, and spatially define cold water refuges along the lower Willamette River and select tributaries, and therefore focus on off-channel features (alcoves, side channels), tributary inputs, and deep main channel pools, as well as comparable main channel readings.
