It’s truly fascinating to learn about the rich history and underwater wonders of Lock 21 in the Long Sault Parkway. The fact that Lock 21 was built back in 1885 as an attempt to conquer the Long Sault rapids showcases the engineering brilliance and determination of that time. Its transformation from a crucial part of the canal system to an enticing destination for divers is both impressive and inspiring.
Swimming through the gates of Lock 21, spanning an impressive 270 feet, must be an awe-inspiring experience. The width of 45 feet and the clearance of 14 feet over the sill demonstrate the scale of this submerged lock. The underwater exploration of this lock not only provides an unforgettable adventure for divers but also offers a glimpse into the history and challenges faced by early navigators.
The evolution of the canal system, particularly the deepening and widening of the canal, highlights the significance of Lock 21 and the entire canal network in enabling smoother trade and transportation. It’s evident that these engineering feats played a vital role in shaping the region’s history.
The transformation of Lock 21 in 1958 to create a head pond for a hydroelectric dam and to accommodate the new St. Lawrence Seaway demonstrates the adaptability of the waterways to modern needs. This change not only harnessed the power of the river current for electricity generation but also paved the way for larger vessels to navigate through the St. Lawrence Seaway.
The fact that the Lost Villages have also become a dive attraction adds another layer of historical significance to the area. The opportunity to see pioneer houses that were saved from flooding is a unique experience that connects divers with the past.
I am intrigued by the practical details you’ve provided for diving at Lock 21. The use of guide ropes, the strong current, and the importance of bringing a light to explore chain wells and manholes all emphasize the need for careful planning and preparation. The location details you’ve shared, including the accessibility from Macdonell Island and the presence of facilities like picnic tables and a snack bar, make it easier for divers to plan their visit.
Overall, the story of Lock 21, its historical context, and its present-day role as a dive attraction are captivating. It’s a reminder of the continuous evolution of our waterways and the remarkable stories they hold. Thank you for sharing this insightful and adventurous journey! 🤿🌊
