Fishing different waters yearly reminds me that each is different as far as fish locations. Seasonal pattern locations are narrowed down but summer and fall patterns differ lake to lake. Weed beds and depth changes are for me the best way to rule out where fish are
unlikely to be vs flat uniformly weedless bottoms.
Photos of lures that caught fish tell me the
pattern-of-the-day - a combination of lure type/speed/depth fished and areas that
striking fish were. If I used a float and soft plastic and documented fish caught, that was the pattern for that hour or hours and season. If a jig & trailer did well on mid-lake humps in August two years in a row, photos are proof vs a vivid imagination that those areas actually did well in the middle of the day vs shoreline areas.
Logs are like a personal encyclopedia of everything we've experienced and hopefully retained when it comes to where and how we caught fish. Lure variety in my case dictates photo proof of catches or lures go back in storage when they fail consistently. Even small fish caught on lures are photographed because small lures do catch large fish - some better than others such as this 2lb bass caught on a small soft plastic design:
...and this
14" crappie on the same day:
Again for many fishing is a simple matter: go out, spend some time with buddies, catch a few unless luck/chance dictates better. Having fished tournaments for four years, I found out early that not knowing the waters fished - even a little - put me and my partner at a great disadvantage wasting time trying to find key structure areas and patterns. I chose not to do that again because the feel of the strike is everything!
