I know some anglers like to split big waters into sections, but in my mind, this is only worth doing if the lake is in distinctly different sections to start with. If somewhere has two or three main bodies, the Tench tend to stay in the same areas at times, and as these areas are still about 50 acres in size it’s not easy. In my experience, you can bait an area and get fish feeding, but as soon as the wind changes the fish will be gone bait or no bait. It is in their instinct to feed with the wind, and this is what they will do as it is how they are used to finding food. I use the strength of the wind as a gauge to give me an idea of how far to go down on the wind to start looking. If there is a light wind, as a rule, they will not go down fully on it, as it gets stronger there’s more chance of them moving further down the lake as more natural food will get pushed down. If the wind is Gail force or close to it there is a very good chance, they will be well down the lake, on the bottom of the wind, but seeking refuge in a Back Bay or bay to the side or behind a point or outcrop of bank. At times this is going to involve looking for hour’s morning and evening, which is the most likely the time that they are going to show.
Having a good understanding of the underwater features is a massive help and a must in my book. In one of the big pits that I fish the Tench will readily roll and show themselves. In another 120-acre water, they seem to be very shy of doing this, but there are other signs like fizzing and tail slapping, which is obviously a massive help. As we all know, Tench like weed and are nearly always found in the vicinity of weed either for food, safety from predators. On some waters where I fish the weed can grow up to nine or ten feet in the water. Tench seem to like areas where the depth changes, i.e. marginal slopes, ledges, steep drop-offs, islands, bars, plateaus and humps and of course these high weed beds and they are all good starting points.
