Jigman,
The King County web site has a section called "King County Lakes Data". The temp was 49.6 degrees at 7 this morning.

Sorry...don't know how to create a link but after you get to the King County website go to Environmental links then under the section on Water Resources click on Lakes Topics and finally select Daily Water Quality Data. The actual path is below.
