I kept tide charts, rain amounts, moon cycles, gauge height, barometric pressure, and all encounters with anything swimming, or walking, that wasn't human. For like 3 years. it got me dialed in on what days to expect a fish and what days to expect a hike.
It amazed me the number of deer and elk sightings, that I caught fish around... and I was able to dial in a few lower holes on some small rivers that I could go "x" amount of time from low tide early in the season and encounter fish that came in with the tide. I also found that if the animals were up late the fish seemed to eat at night also, so the best bites were later in the am after they got hungry again.

I stopped keeping track after I started noticing that more people on the river or bay reduced the number of fish I caught. it made me want to only fish midweek. and the Job didn't like that....
