After a number of years of fishing in tournaments, I got a system down that seemed to work. The final fishing log included the normal stuff such as weather and water conditions, season, what stage the fish were in, along with the results of the tournament.
But, I also took it step further. Prior to either a pre-fishing or tournament day, I would write out a milk run plan for the body of water, and then transfer it to a copy of the lake map. After I got home from fishing, I would write down how the day went, and I would also mark a "master map" with the location of each keeper that I had caught. I kept a file for each different lake that held all of the logs for that lake.
My trip log for a lake such as White Lake might have started with something like this:
Plan to start on slab wood pile in front of "A-Dock". Baby Spook, Tandem Spinner, Black/Chart. Power Craw, Avacado/Christmas Kalin's Grub.
If I'm catching, work onto "B & C Docks". If not, work shoreline to leather plant. Remember to work Power Craw along this shoreline.
Next move over to Nellie's dock if boat is still there. If not, head up to ring the bell.
This plan would continue on until it covered a full days worth of spots to hit. When I got home, I would write something along the lines of this:
Started on the "A-Dock" and caught two dink SM's. Moved onto the shoreline heading towards the leather plant. Picked up one good LM (15") on Power Craw. Picked up a keeper SM (14") on grub in front of water release at the plant.
Moved over to Nellie's dock and picked off a nice keeper LM (19") with craw.
Moved up the lake to ring the bell and caught a SM (15") and two dinks.
Using this story type fishing log along with a marked map allowed me to visualize my day on the lake. After a number of trips to White Lake, I could also see the spots where I caught most of my fish. It also showed me the places I hadn't even tried, and that might be worth some time spent during a future pre-fishing trip.
With today's technology, I would probably switch out the lake map for a GPS unit that showed numbered waypoints. But I think the "story" is still an important consideration because you can think out the types of lures, and the results.
