Swimming is awesome. It's low impact but high intensity cardio. If done correctly, it can also allow you to warm up and stretch the body properly. You'll use some muscles you've never used before from just lifting, and in different ways too.
IMO, any type of physical activity isn't counter productive... Are you working out for fitness or are you doing something very specific? I think that is what Quick6FE was getting at.
If you are lifting to achieve some sort of very specific goal, then you should have a very specific plan (which I doubt since you don't even keep a written log of your lifts). Swimming is just a different type of workout.
