Johnson Creek Basin Hydrologic Monitoring

Project Number OR175

Welcome to the Johnson Creek Basin Hydrologic Monitoring Home Page.

The U.S. Geological Survey (USGS) and the jurisdictions in the region are providing hydrologic data for the Johnson Creek Basin. Real-time surface-water and ground-water data, as well as historic data and analyses, will help improve our understanding of the hydrology of the basin.

Here you will find a description of the study and other useful information pertinent to this work.
