Thanks Guys. 46 degrees seems too close for comfort especially considering the mild winter. I figured we were safe this year but more curious about how cold it has to get to get water temp down to 42. Bob, I think you said on average one out of 5 years the cold will get us but if we had a mild winter and area lakes got to 46 it doesn't seem to have to get much colder to put us in danger. Thanks for the lesson on water temps. I learn something new every day especially on this forum. Any further comments on above would further my education.
