Its a really good idea if you are not too busy to do it. When I was younger (aka during college, and before kids) I kept up a really good log.

I just got a daily planner, and filled out what happened on each day, flows, weather, technique or anything else I thought was important. Even more, I filled it out if my network had success and I used the internet to verify flows, weather, etc to figure out what was happening.

I superimposed the net-days over all of that as well. Sometimes I looked on the internet and would write down information I gleaned from it, when people who fish the same places I do would post reports.

Then in the margins I would write down hypotheses, and opinions on what was happening with the fish. I would write anything I thought would give me an edge if the same conditions presented themselves. Sometimes I pasted pictures of the color of certain rivers in there as well. I would just stop by on my way by and take a picture of the water for future reference. This started when we still took pictures with film.

How much would someone pay for that? It basically covers about 5 rivers within an hour of me here, you can all probably guess them.

Eventually, I got to where I knew what was going on enough that I didn't have to do it so I quit. Now I just go back through the pictures on my phone, I really should send all the texts from my fish network to the cloud somewhere to remember that as well.

See you on the river 2/8 MetlheadMatt!
