Rules
Europe's electric-only waters: the complete list
Where combustion engines are banned but electric boats are allowed: 246 confirmed lakes, reservoirs and canals across 14 countries, with the rule for each.

Across Europe, a growing number of lakes, reservoirs and city canals are closed to petrol and diesel engines but open to electric boats. We went through the regulations country by country and confirmed 246 named waters in 14 countries. The register covers a fifteenth, Switzerland, with entries we have not yet been able to verify. This article summarises what we found. The full, filterable register is at Electric-only waters.
What counts as electric-only
No two countries write the rule the same way, so we sorted every entry into one of four types.
- Electric only. Combustion engines are banned for private leisure boats and electric drive is allowed, often with a power limit.
- Permit or quota. Combustion engines need a permit that is capped in number or hard to get. Electric boats get permits more easily.
- Seasonal or time ban. Combustion engines are banned for part of the year or part of the day.
- Zone, route or boat type. The electric requirement applies to part of a water, or to one kind of boat such as rental craft.
We left out waters where private boats may not use any motor at all. Those are quiet waters, but they are not electric waters.
The numbers by country
| Country | Named waters | The short version |
|---|---|---|
| Austria | 77 | Combustion bans across Tyrol, Upper Austria, Carinthia and Burgenland |
| Czech Republic | 61 | One decree bans combustion engines on 61 reservoirs |
| Poland | 35 | County councils declare silence zones, mostly in Masuria |
| United Kingdom | 20 | The Lake District's small lakes |
| Germany | 15 | Federal reservoirs, Steinhuder Meer and a permit system in Bavaria |
| Netherlands | 11 | City centres and marked electric routes |
| Spain | 8 | Reservoirs in the Guadiana basin |
| Hungary | 5 | Lake Balaton, Lake Velence and Lake Fertő |
| Italy | 4 | The lakes around Rome |
| France | 4 | Aiguebelette, Sainte-Croix, Saint-Cassien and Paladru |
| Finland | 3 | Lake-by-lake decisions |
| Sweden | 2 | Drinking water lakes near Gothenburg |
| Denmark | 1 | Furesø, by permit |
Norway is the fourteenth country. Its rule covers a category instead of named lakes: on every lake smaller than 2 km², a municipality may allow electric motors up to 800 W.
Switzerland is the fifteenth country in the register. Its entries come from earlier listings that we have not yet confirmed against cantonal rules, so they are marked unverified and not counted in the 246. See electric boat rules in Switzerland for the national rules.
Austria has the most, and the strictest
Austria regulates lake by lake and state by state. The result is the densest set of rules in Europe.
In Tyrol, combustion engines are banned on 33 named lakes. Electric motors are limited to 500 W, with Achensee as the exception at 2,200 W. In Upper Austria, 17 smaller lakes allow only electric motors up to 500 W, Hallstätter See allows 1,000 W, and Mondsee bans combustion engines all year. On Attersee and Traunsee the ban is seasonal, from 1 July to 31 August, plus every night between 21:00 and 07:00.
Carinthia works with quotas. Wörthersee has a ceiling of 335 private boats with combustion engines and a waiting list. In Burgenland, Neusiedler See is closed to any vessel that has a combustion engine on board, even one that is switched off. We cover all of this in detail in Austria's lakes: where combustion engines are banned.
The Czech Republic and Hungary ban by law
The Czech Republic takes the simplest approach. Decree 46/2015 lists 61 reservoirs and 61 river sections where vessels with combustion engines may not be used. Hybrids count as combustion. The decree does not restrict pure electric motors.
Hungary bans small boats with internal combustion engines on Lake Balaton, on all of Lake Velence and on the Hungarian part of Lake Fertő. Exemptions need a one-year operating permit for a specific purpose, such as rescue or regatta support. The ban does not cover electric motors.
Poland, Germany and the rest
In Poland, county councils can declare silence zones under environmental law. The county of Mrągowo lists 25 lakes and rivers. Neighbouring Giżycko and Pisz add ten more. Local sources confirm that the Giżycko and Pisz rules ban combustion engines only, although the signs on site sometimes suggest otherwise.
Germany is a patchwork. The federal rule for Edersee and Diemelsee excludes leisure craft with combustion engines. Steinhuder Meer allows electric motors up to 10 horsepower. Bavaria as a rule issues permits for combustion engines on two lakes only, Starnberger See with 280 and Ammersee with 150.
France has few such lakes, but the rules are clear. Lac de Saint-Cassien got a new prefectoral order on 30 March 2026: combustion engines are banned on the whole reservoir, and electric boats may run at up to 10 km/h with a maximum of 18.4 kW.
In the Netherlands the change is happening in cities. Amsterdam's centre has been an emission-free zone for pleasure craft since 1 April 2025. See Amsterdam's emission-free canals.
Places that are often listed by mistake
Several well-known waters appear on lists like this one without belonging there.
- Königssee, Germany. Private craft are banned completely. Only the ferry company's electric boats operate.
- Lake Annecy, France. Combustion engines are allowed. Personal watercraft are not.
- Lake Bled and Lake Bohinj, Slovenia. Private electric craft are banned on both.
- Geirangerfjord and Nærøyfjord, Norway. The zero-emission rule applies to passenger ships, not private boats. See Norway's zero-emission fjords.
- The northern end of Lake Garda, Italy. All private motor boating is banned in the Trentino part, electric included.
The limit matters as much as the ban
Electric-only does not mean any electric boat. Most Alpine lakes set a power limit that fits a small tender or a fishing boat and nothing faster. Read the limit before you travel. A lake that allows 500 W is a different place from a reservoir that allows 18.4 kW.
Three more things are worth checking each time:
- Permits. Some waters require a navigation permit for every craft, as Lac d'Aiguebelette does.
- Seasons. Steinhuder Meer is closed to boats from 1 November to 19 March.
- Local signs. Where a sign and a list disagree, the sign and the local authority decide.
How we built the list
Every entry in the register links to its source. We read each one on 8 October 2026. Entries marked as official are based on a regulation, a decision or an authority's own page. Entries marked as secondary come from press, tourist boards or trade sites and should be confirmed locally.
The list is not complete. Europe has thousands of small lakes with local rules, and Switzerland, Portugal, Sweden and Denmark have no single register to check. If you know a water that belongs here, tell us and we will add it.
Questions
Which European country has the most electric-only lakes?
In our register, Austria has the most named waters with 77, followed by the Czech Republic with 61 reservoirs and Poland with 35 lakes and rivers.
Can I use any electric boat on an electric-only lake?
Not always. Many lakes set a power limit for electric motors. Tyrol allows 500 W on most lakes, Hallstätter See allows 1,000 W and Lac de Saint-Cassien in France allows 18.4 kW.
Is Königssee an electric-only lake?
Only for the ferry company. Private craft of every kind are banned on Königssee, including kayaks and paddleboards.
Is Lake Annecy closed to combustion engines?
No. Combustion engines are allowed on Lake Annecy. Personal watercraft are banned there, which is a different rule.
How often do these rules change?
Often enough to check before every trip. Saint-Cassien got a new prefectoral order in March 2026 and Amsterdam's zone started in April 2025.
