Automated, high-frequency, water quality data collection systems (referred to as ‘moorings’) allow continuous measurements of physical, chemical, and biological water quality parameters as well as meteorological parameters. The data generated by these systems allow users to characterize variability over time on numerous scales (e.g., daily, seasonal, annual, inter-annual). The data can also be used to establish baseline conditions, populate numerical models, and provide data for management decisions.

The map shows the locations of currently active and inactive moorings and surface meteorological monitoring locations in Puget Sound maintained by King County. To view the latest data, click the active site pins on the map. You can also download the latest data by selecting the Download Data link.
