Sluis- en Stuwcomplex Amerongen, Hydroelectric power station and lock complex in Utrechtse Heuvelrug, Netherlands
The Sluis- en Stuwcomplex Amerongen is a combination of lock and weir on the Nederrijn River, designed to control water levels while allowing vessels to pass through. The lock chamber stretches about 260 meters (850 feet) long and can be divided into sections to accommodate different ship sizes.
Construction started in 1958 and finished in 1965 as part of a broader water management strategy for northern Netherlands. The project emerged when the country was modernizing its infrastructure to handle rivers more safely and efficiently.
The complex reflects Dutch practices of living with rivers and harnessing their power, traditions that have shaped the region for centuries. You can observe how the area balances human needs with respect for the waterway's role in the landscape.
The site is accessible and offers viewpoints to observe the lock and weir operations from different angles. Visiting during operating hours gives you the best chance to see the machinery and water levels in action.
The facility powers itself through a 10-megawatt hydroelectric generator built into its operations, making it a working example of navigational and renewable energy infrastructure in tandem. Few visitors realize the electricity produced here comes from the river's own flow while boats pass through.
