Lake Tisza, an angler's water maze

First-time visitors to Tisza-tó (Lake Tisza) are usually surprised by two things: how big it is, and how little it resembles a "normal" lake. Instead of open water you find a tangle of islands, oxbows, channels and reed beds, where ten minutes in a boat takes you into a completely different world. That variety is the magic of the place, and it is exactly what you need to prepare for.

What exactly is Lake Tisza?

Tisza-tó is an artificial reservoir created by building the Kisköre barrage. The dam was finished in 1973, the reservoir has been filled regularly since 1978, and it got the name Tisza-tó in 1988. At about 127 square kilometres, it is one of Hungary's largest standing waters.

It is usually divided into four main basins:

• Poroszló basin: the busiest and most accessible part, with plenty of open water and channels.
• Tiszavalk basin: the shallowest, and much of it is under strict nature protection.
• Sarud basin: reedy, full of bays and quieter.
• Abádszalók basin: the deepest, with larger stretches of open water.

The water level changes with the seasons: the reservoir is filled in spring and drawn down in autumn. This has a big effect on the fishing, because the same spot can be completely different in summer and in winter.

Which fish live here?

The lake's fish fauna is rich; for anglers the most important species are:

• Wels catfish: one of the lake's most popular targets, found in summer in the deeper sections and at the mouths of oxbows.
• Pike: the classic predator of reed margins, weed beds and bays.
• Zander and Volga zander: in deeper areas with a harder bottom.
• Asp: hunts in open water and along the flowing sections of the channels.
• Carp and tench: in reedy bays and silty, weedy areas.
• Bream species: shoals of common bream, silver bream and roach, often in good numbers.

Invasive species are present too, such as the Prussian (gibel) carp and the black bullhead. Under the rules these must not be returned to the water, so check what the current regulations say about them.

How to find your way through the maze

Navigation is Lake Tisza's biggest challenge. A few lessons that help a lot:

1. Carry a map and GPS. The islands and reed beds look very similar, and it is easy to get lost at dusk.
2. Follow the marked waterways. In some parts of the lake you may only travel on designated routes, and elsewhere motorboats are banned.
3. Watch out for stumps and shallows. Remains of former floodplain forest lie hidden underwater, which can be dangerous both when boating and when fishing.
4. Plan around the weather. In the open basins the wind quickly raises waves.
5. Tell someone where you are going. There is no mobile signal everywhere.

If you don't know the area yet, the map search lets you quickly scan the fishing spots along Lake Tisza and nearby waters.

From the bank or from a boat?

You can catch nicely from the bank too, especially along oxbows, backwaters and flushing channels, where the water is calmer and the fish more concentrated. These areas also give fish good shelter in winter. But you only get to know the real Lake Tisza from a boat: that is how you reach the reedy bays, the passages between islands and the drop-offs. If you don't have your own boat you can hire one locally, but always clarify first where you are allowed to navigate and fish with it.

Seasons and methods

Spring

As the reservoir fills, the water floods the vegetation and fish move into the shallows. Carp and bream can be caught well in warmer, reedy bays. During spawning, catch bans apply to several species, so pay particular attention.

Summer

Prime catfish season. Clonking, ledgering and spinning all work, and the early morning and evening hours are best. Pike are active along the reed margins as well.

Autumn

The water cools and the predators start feeding. This is when spinning for pike and zander is most productive, and asp hunt in open water.

Winter

With the lake drawn down, fish retreat into deeper sections, oxbows and channels. For the winter period the rules typically get stricter, for example restricting night fishing and spinning in certain basins.

Rules and nature protection

Since 2025 the fishery on Lake Tisza has been managed by the Hungarian National Angling Association (MOHOSZ), and the local rules are published by its Lake Tisza office. You need a Hungarian state fishing licence and a valid area ticket. Size limits, bag limits and closed seasons have changed several times in recent years, so check the latest rules before every season.

Much of the lake is overseen by the Hortobágy National Park Directorate. Bird reserves and strictly protected areas are off limits even with a ticket, and nesting sites should be given a wide berth. Protected fish live in the lake as well, including the strictly protected zingel; if you catch one, release it immediately and gently.

The basic rules of fishing on Lake Tisza:

• handle fish with wet hands, on a mat;
• carry a disgorger and pliers when fishing for predators;
• when camping, the rubbish is yours, so take it with you;
• don't cut reeds or create new swims without permission.

Summary

Lake Tisza is not a water you get to know in a day or two, and that is exactly what makes it special. If you prepare properly for navigation, respect the protected areas and follow the current rules, it can deliver a huge range of experiences from catfish to pike. On your first visit it is worth starting with an easily accessible basin and expanding your explored area from there.
