USGS 12300110 Lake Koocanusa at international boundary

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text

Station operated by the USGS Wyoming-Montana Water Science Center as part of the Transboundary Assessments of Water Quality in the Pacific Northwest.


Water quality data provided here are collected from an automated water quality profiling station that samples at one meter intervals within the lake water column.

A data visualization tool that provides time-series color maps of specific conductance and water temperature profile data is available on the project webpage at: https://www.usgs.gov/centers/wyoming-montana-water-science-center/science/lake-koocanusa-temperature-and-specific

This station managed by the Helena Field Unit.
