I've been keeping a fishing log for about the past 20 years or so. I pretty much keep track of the items you listed, in addition to specie, number and size of fish caught. I'm not sure I've ever analyzed the data contained to draw any hard and fast conclusions, but it is fun to review how fishing was back in the day.

p.s. I also keep track of my fishing companions on each trip as well as notes regarding any new of special equipment I might have used.
