Processed Lake Tahoe and Lake Geneva Water Levels

This processed data set contains the water level elevation in Lake Tahoe (2013-2015) and Lake Geneva (1974-2013). The higher frequency oscillations in the data show the periods and damping of the surface seiches in both lakes. In Geneva, there are three points where this data was measured and how the water level at the different points at the same time varies indicates further properties of the seiche.

Temporal coverage:

From 1974 to 2015

Geospatial area:

North 39.25° East -119.925° South 38.94° West -120.15°

North 46.52° East 6.93° South 46.205° West 6.15°


Data collection method:

The time series data used in the Random Decrement Technique (RDT) analysis of Lake Geneva took the form of water elevation data collected at three locations; location 2026, 2027 and 2028. This data had a sampling rate of 10 minutes and was continuously collected between 00:00 on 1 January 1974 and 23:50 on 7 January 2013. The RDT analysis for Lake Tahoe was carried out using water pressure head data collected at a buoy located at Homewood. Three time-series data sets were utilized in the analysis; 30 July 2013 00:00:00 to 6 December 2013 23:59:30, 1 January 2014 00:00:00 to 10 May 2014 23:59:30, 6 January 2015 00:00:00 to 15 May 2015 23:59:30. All data had a sampling rate of 30 seconds.

Data processing and preparation activities:

The raw Lake Geneva data was collected by the Swiss Federal Office for the Environment and was provided by Damien Bouffard of the Swiss Federal Institute of Aquatic Science and Technology. The files were received as ascii files, cleaned, and converted to the Matlab files provided here. The raw Lake Tahoe data was provided as csv files by Geoff Schladow of the University of California at Davis and converted to the Matlab files here for the RDT analysis.

Technical details and requirements:

The processed data is in Matlab format and must be viewed using Matlab. For access to the original data files, please contact Damien Bouffard or Geoff Schladow.
