FYI:
Found the following link on "another board" while reading about crappie fishing. The database is maintained by the Murray State University's Hancock Biological Station, which is located ~1 &1/2 miles south of Ken Lake.

The database gives present (updated every 30 minutes) and histortical data for about every parameter you would wish for. You can view the data in table or graph format. For example, I was able to plot Lake Elevation, Temperature, Turbidity and Dissolved Oxygen for March 2007 - March 2008. Interesting information, if you like to look at trends.

Good Fishing to all,
