A Unique Underwater Attraction Reopens in Worcester
A popular and unique underwater attraction in Worcester has recently reopened for another seven months, offering visitors a rare opportunity to witness aquatic life in action. The Diglis Fish Pass, which has been a key feature of the River Severn since its construction in 2021, has welcomed its first users as the winter season comes to an end.
The fish pass was created to provide aquatic species with a safe route to travel upstream, following the construction of the Diglis weir in the 19th century. In addition to its ecological purpose, the pass also features an underwater river viewing area, making it the only one of its kind in England. Visitors can sit in this special chamber and observe over two dozen species of fish swimming past through a large glass window.
Access to the viewing area is via a staircase that leads from the riverside down into the chamber. This unique setup allows guests to experience the river’s ecosystem up close, providing both educational and recreational value.
The Fish Pass officially reopened on Wednesday, March 18, 2026, after being closed for much of the winter. Mark Miles, the visitor service manager for the Canal and River Trust, explained the challenges faced during the closure: “There was a lot of debris and a lot of algae on the windows that needed cleaning after the winter. The river is still quite high, so the weir is only just showing, and only about half of the Fish Pass is open. However, it is designed to cope with floods.”
Miles added that as the river levels drop, the focus will shift to removing any debris that might hinder the movement of fish. “It is just a question of looking for any debris that needs moving to allow for fish to pass as normal,” he said.
Best Time to Visit
On the opening day, visitors were already able to spot several bleak and a pike, but more aquatic life is expected as water temperatures rise. Mr. Miles highlighted the best time to visit: “The best time to come and see the fish is anytime from the end of April to the beginning of June, because that is when a lot of the fish are moving upstream to spawn.”
He explained that the movement of fish is not limited to searching for food or shelter. “You’ve not just got the fish moving up and down the river for food and shelter, but they are migrating upstream as well,” he added.
Regular Drop-In Sessions
To encourage continued public engagement, Fish Pass drop-in sessions are held frequently throughout the week until October. These sessions provide an excellent opportunity for visitors to learn more about the local wildlife and the importance of the fish pass in maintaining the health of the River Severn.
For those interested in attending, a full list of upcoming drop-in sessions can be found at canalrivertrust.org.uk.
Conclusion
The reopening of the Diglis Fish Pass marks an important milestone in the conservation efforts along the River Severn. It not only supports the natural migration of fish but also offers a unique educational experience for visitors. As the seasons change, the Fish Pass will continue to play a vital role in preserving the biodiversity of the region while providing a fascinating glimpse into the underwater world.
