I checked it yesterday and I got a reading of 52.5 degrees. Today I got 54.3 degrees. Is my temp gauge off? I can't believe its already over 50. Has anyone else taken a reading the last couple of days. I also took a reading on the main lake at Dillon yesterday and the temp was 59.7 but it was taken on the black asphalt road to get down in there so It might be off a couple degrees.
