How to find a ledge or hole in a body of water

How to find a ledge or hole in a body of water. Knowing how to locate ledges and holes is one of the key skills that distinguishes an experienced angler from a novice. In 80–90% of bodies of water, large fish (bream, pike perch, perch, pike, taimen, lenok, grayling, and broad whitefish) are found in depth changes: ledges, drop-offs, pits, tables, and ridges. Without understanding the bottom topography, even the most expensive tackle and the perfect bait are often useless. This article provides a highly practical guide on how to quickly and accurately locate a ledge or hole in a river, lake, or reservoir using only available tools and observation.

What is a brow and a pit in simple terms?

• A drop-off point is a sharp or gradual change in depth (from 0.5–1 m to 3–6 m or more). It marks the boundary between the shallows (coastal zone) and the channel/deep part of the river. Food (shells, larvae, and fry) concentrates at the drop-off point, so fish are always present there.
• A pit is a localized depression in the bottom (from 4–6 m to 15–30 m or more). Pits are wintering and feeding grounds for large fish. Small fish accumulate in them, and predators come after them.

On rivers, the most common locations for eyebrows and pits are:

• under the steep banks,
• at the bends of the river (the outer side of the bend),
• below the riffles and rapids,
• at the mouths of tributaries,
• on the border of the main channel and backwaters.

On lakes and reservoirs - this is:

• dumps from the coastline,
• underwater banks and tables,
• the bed of a flooded river,
• deep ditches and holes in the middle of the reservoir.

Ways to find a brow or pit

1. Visually (the simplest and fastest method)

• A steep bank→ there's almost always a sharp drop-off or pit beneath it. The steeper and higher the bank, the deeper the water beneath it.
• River bend→ the outer side of the bend is a classic pit or drop-off. The inner side is a shallow or riffle.
• The boundary between the current and standing water→ where the stream suddenly slows down - almost always the edge or the beginning of a hole.
• Foam, debris, bubbles→ a foam line or accumulation of bubbles often runs along the edge.
• Water color→ a sharp transition from light (shallow) to dark (depth) - this is the edge.
• Vegetation→ the boundary between reeds/grass and clear water often coincides with the edge.

On the Putorana Plateau, visual search is especially effective: here, steep rocky banks, canyons, and sharp river bends create classic cliffs and pits right under the shore. Just look at the coastal topography and you'll immediately see where the water depth is.

2. Using a depth gauge or echo sounder

The most accurate way.

• Move the boat along the shore or across the river - the echo sounder will show a sharp drop (from 1.5-2 m to 5-8 m or more) - this is the edge.
• Look for “steps” – several changes in a row (for example, 2 m → 4 m → 7 m) – this is a classic edge with a shelf.
• The pit looks like a local depression with a flat bottom at the bottom.
• In reservoirs, look for a flooded riverbed - these are deep ditches with ridges along the edges.

On the Putorana Plateau, a fish finder is especially useful in large lakes (Lama, Keta, Khantayskoye, Sobachye), where the terrain is very steep: from 2 meters below the shore to 50–100 meters in the center. The edges here are almost always under steep cliffs.

3. Float-depth gauge (budget and accurate method)

• Tie a 20–50 g weight to the line, attach a stopper above the weight, and a float between the stopper and the weight.
• Cast and watch how the float settles: if it settles horizontally, the depth is shallower than the leader length. If it settles vertically, the depth is deeper.
• Move the stopper until the float is at an angle of 45–60°—this means that the sinker is lying on the bottom, and the float shows the actual depth.
• In this way, you can quickly “pass” the area and find the drop (edge).

4. The "step wiring" method (spinning)

• Cast a jig or spoon, using a step-by-step method.
• If the bait takes 3-4 seconds to reach the bottom, the water is shallow.
• The fall time increases sharply (7–10 seconds or more) – you have found a drop-off or edge.
• A long fall without touching the bottom is a pit.

On the Putorana Plateau, this method is ideal for rivers: sharp drop-offs and holes here are often located just 5–15 meters from the shore.

5. Folk omens and landmarks

• Birds (seagulls, terns) above the water - small fish, followed by a predator, often on the edge.
• Bubbles and "boiling" of water - large fish are digging in the silt on the edge or in a hole.
• The line of foam, debris, and algae almost always runs along the edge.
• A steep bank with overhanging trees - there is almost always a hole underneath it.

How to fish on the edge and in a hole

• On the edge - wiring along the slope, a step with a jig or a spoon, a float in the wiring, a feeder on the edge of the slope.
• In the pit, use a bottom fishing rod, feeder rod, mugs, and tip-ups on the bottom or in mid-water. Spinning rods are used with a step-by-step retrieve or drop-shot.

On the Putorana Plateau, cliff edges and pits are the main fishing spots. Grayling are found on the upper part of the drop-off, lenok and char on the middle part, and taimen in the pits under the cliffs. A well-chosen cliff edge can yield 5-10 trophies in a morning.

Conclusion

Finding a break or a hole isn't magic, but a skill that comes with practice. Start with a visual inspection of the shore, use a depth finder or a float-depth finder, and learn to read the water by bubbles, foam, and birds. In most bodies of water, 80% of big fish are found in the depth changes. Master this skill, and your fishing will become much more productive.

On the Putorana Plateau, cliffs and pits are literally underfoot: steep rocky banks, canyons, and sharp river bends create ideal conditions for catching trophy taimen, lenok, char, and grayling. Just glance at the shoreline and you'll immediately see the depth and where the fish are. Learn to read the bottom, and even in unfamiliar waters, you'll always find fish. Good luck on the water!
