When out to Lake Arthur today.  Put the boat in at the 528 launch at 11am, water temp was 43 degree, air temp was 51 degree and it was sunny with light winds.  Around 1pm I was working a little break line with a stickbait and got this nice largemouth.  Fished till around 6 pm and ended up getting one more largemouth and had few more hits.  Water temp was 48 degrees and air temp was 58 degree when I was leaving.  All in all a great first day on the water.
