Peat pit lakes and how to fish them

At first glance a peat pit lake can look unwelcoming: brownish, tea-coloured water, boggy banks, walls of reeds and water lilies everywhere. Yet these waters often hold a rich fish population and a genuinely quiet, unspoilt fishing experience. The secret is that here the key is not a hard bottom or clear water, but weed, silt and oxygen.

Where do peat pit lakes come from?

Peat builds up in mires, in waterlogged ground, from slowly decaying plant remains. Where it was once dug – for fuel or for horticulture – the pits filled with water and over time turned into lakes and lake systems of their own. They are often irregular in shape, broken up by bays, narrow channels and islands.

The water is stained brown by dissolved humic substances, and its clarity varies from lake to lake. Depth is usually moderate, but the firm bed is covered by a thick layer of loose organic silt, so the real "bottom" is hard to reach.

What to watch for on the water

A few features of peat lakes shape the whole approach:

• Deep, soft silt: a rig laid on the bottom sinks in easily and the bait disappears from the fish's view.
• Lots of plants: weedbeds, water lilies, reeds and reedmace provide cover and food, but make playing fish harder.
• Oxygen balance: all that decaying organic matter uses up oxygen. At dawn in muggy summer weather and under long ice cover the fish are noticeably sluggish, or move to fresher, windier areas.
• Gas bubbles: bubbles rising from the bottom often come from decomposing silt and do not necessarily mean feeding fish.

The dark water warms quickly in spring, so fish in shallow, sunny bays become active early. In summer the best times are often morning and evening, and in autumn, as the weed dies back, the fish move more and are easier to find.

Species and their behaviour

The classic residents of peat lakes are tench, crucian-type carp, rudd and pike. Carp are stocked in many places, and catfish or zander turn up too, mainly in deeper, larger lakes. Non-native brown bullhead and pumpkinseed are also common and will quickly strip small baits.

In weedy water fish don't like to roam open areas. Look for the edges of weedbeds, clearings between lily pads, the strip in front of the reeds and the mouths of channels. Bear in mind that protected species can live in wetland habitats, such as the strictly protected European mudminnow; if you catch one, release it immediately and gently.

Rigs for a soft bottom

Because of the silt, the goal is to present the bait above the soft layer, where fish can see it:

• Float fishing: a finely shotted float rig in the gaps between weeds is the classic method for tench and crucians. Let the bait just touch the bottom or hover above it.
• Buoyant or balanced baits: for carp, pop-ups or balanced baits and a longer hooklink help keep the bait out of the silt.
• Light leads, gentle baiting: heavy leads and large amounts of groundbait bury themselves deep. A little loose, light feed is worth more.
• For predators: weedless lures, surface lures and soft plastics worked along the weed edge are great for pike.

With so much weed, your line and hooklink should be comfortably strong for the size of fish you expect, so a hooked fish doesn't get stuck and leave tackle behind.

Safety on the bank and on the water

Peat lake banks are often boggy, and in places they are covered by floating mats of vegetation. These may look solid but will not carry a person – never step onto them. Fish only from designated swims or platforms, and take extra care when moving around alone or in the dark.

Be especially careful with fire: dry peat is hard to extinguish and can keep smouldering underground. Don't light open fires and watch your cigarette ends.

Conservation and rules

In Hungary, mires are protected by law (ex lege), and many peat lakes are part of, or lie close to, such protected sites. That can mean seasonal or area restrictions, closed sections and rules on using boats. Before you go, check the fishery rules and the current regulations of the managing club or owner; size limits and closed seasons can differ from water to water.

A short checklist:

1. Check the fishery rules and any protected-area restrictions.
2. Choose a safe, designated swim.
3. Prepare for a soft bottom: buoyant bait, lighter lead.
4. Bring an unhooking mat and landing net for careful handling.
5. Take your rubbish and old line home.

Summary

A peat pit lake is not the place for quick, flashy catches, but for the patient, observant angler. If you read the weed, keep your bait above the silt and respect the protected surroundings, you can have some truly memorable sessions. Looking for a new water?
