I fish a lake that is deep at one end and shallow in the other end. Baby bass are everywhere at all times, but big bass are in specific places with the dominating factor being water level. Water temp. varies very little, and clarity is a main factor, but is dependent on the water level.
In the spring and early summer when the water is low, the big bass are all in the deep end because the shallow end is completely dry. Most of the big bass suspend in large trees in the deepest portion of the lake. Some are on humps in 20 feet of water and a few are on steep points.
When the rain comes and floods the lake, all the big bass move to the shallow end as far away from the deep water as they can get. The first time I fished the lake at flood level, I assumed the bass would still be in the deep end, only pushed up in to the newly submerged vegetation along the bank. I didn't see any reason why they would leave that end with deeper water close by, when they could travel a short distance and be able to hunt and hide in nice green flooded vegetation, which they hadn't seen in months near to where they already were.
While launching my kayak a fellow kayak angler told me to go to the far end of the lake and fish the flooded hay flat. I asked him why, and he told me the giant bass ate frogs at the far end. I thanked him for the advice and started fishing the flooded grass at the deep end of the lake.
At the end of the day I had zero bass over 2 pounds and eventually pedaled all the way to the far end of the lake. The water for the last half mile of the lake was 6 feet or less deep. I found the other angler and he was excited to show me pictures of his bass. He had landed multiple big bass with one over 11 pounds. He had also lost many more, and even lost one breaking his rod horsing a giant out of the grass. All the bass were caught in 3 foot or less of water a half mile away from any water over 6 feet deep. He had the greatest bass fishing day of his life, and I had the worst day I ever had on that lake. I told him I hadn't had any luck, he laughed and said I told you they eat frogs at the far end of the lake. He showed me his popping frog that was all tore up and pictures of all the giant bass he caught on it.
I wasn't surprised that the bass were in very shallow water. After all the visibility was less than a foot, and moving to flooded grass made perfect sense. What I didn't understand is why they would swim a mile to hang out in flooded grass when they could find the same grass a few yards away from where they had spent the past 6 months.
I camped at the lake that night but didn't get any sleep. The noise of the frogs at the far end of the lake was unbelievable. That was when I finally got it through my thick stubborn head. Exactly as I had been told, the big bass were at the far end of the lake, because the frogs were at the far end of the lake. Most of the time the answer to where the bass are is simple, but I for some unknown reason try to make it complex. I caught many bass that next day on a buzz bait with the biggest being 9,5 pounds. I didn't have a frog in the box but I got together with Bait Monkey when I got home and solved that problem.
I ran in to that friendly angler that tried to give me good advice the next spring. He was heading down to the far end of the lake. I told him it was almost dry and even the places where he could manage to get his kayak would not hold bass. They were all in the standing trees in deep water. He attempted to paddled and dragg his way down the lake, He was forced to give up and left early. On his way buy me I told him a had caught one over 10 on a square bill bounced off the tree limbs, and he said it was a fluke. He wouldn't be back until the rains began and the fish started biting again. I guess I am not the only thick headed stubborn fisherman on the lake.
The bass may be deep, shallow, or in-between, but they will always be where they want to be, not where I think they should be, and sometimes the reason is so simple, all I need to do is pay attention to what my eyes and ears are telling me.
