A measure of Lake Tahoe's blues

The article focuses on the measurement of the line attached to Secchi dish sink into the Lake Tahoe. It notes on how long has the plate sink descended to that depth of the lake which wavelength of the light being reflected by microscopic particles of sediment in the water has became smaller than the actual detection of the eyesight. It cites on the importance of measurement since it has been the key to a multimillion dollar drive to keep the Tahoe Blue clear and present everywhere, hence, the Tahoe Regional Planning Agency has showed regulations to preserve the site.
