Not sure exactly which lake temp you are wanting, but Pickwick was around 63 degrees this weekend(4.7&4.8), which was down around 7 degrees from the previous weekend. carl
Lake Weiss was around 60 degrees over the past weekend. Wind gusts were around 10 - 20 mph. Crappie left the docks and shallow water and went to the channels.
I was on Watts Bar, up on the emory, and the water temp was 62 degrees at the mouth of the Big emory. Up around the little emory the water temp was 57, and up in Harriman the water temp was around 53-55 degrees.
