Kirkfield Lift Lock Resumes 'Restricted' Operations

Lock #36 - the Kirkfield Lift Lock - of the Trent Severn Waterway (TSW) holds a unique distinction as being the 2nd highest lock of its type in the world, only surpassed by the Peterborough Lift Lock (Lock #21 of the TSW).

 Unfortunately, this lock suffered an unexpected and serious mechanical failure back on September 2/22 and had been out of service since that time. Although there's no details as to what the failure might have been, there is a short video taken by an on-land visitor during the event. The clip is less than 30 seconds in duration, but one can clearly see water rushing over the sides of the north chamber while the cruise boat 'Kawartha Voyageur' was being lifted up. 

 Here's the video from the incident;

 

 

Clearly, there was water entering that chamber when it wasn't supposed to be!

 When one passes through this lock (as well as the Peterborough Lift Lock), the chambers are made water tight by way of gates that open or close at the top and bottom sides of both chambers, so that excess water doesn't enter, nor escape from the chambers during transit. When the lift or lowering has been completed, the appropriate gate is opened to allow for the boats to exit or enter the chambers. A pretty straightforward practice that we've experienced many times over the past 15 years, all without incident. Seemed to be a very safe and well though out approach on the engineering side, but on this day something went very wrong.

Here's a video from our own up-bound passage (filmed July/22) through the lock that should illustrate how the system works. Note the gate dropping down toward the end of the video. That allows us (the boat) to exit the chamber - and relieving that watertight seal;

Now this is purely speculation on my part, but I'd hazard a guess that perhaps some debris got stuck in the upper gate which allowed the water to go through. Either that, or there was a loss of control for the mechanism that holds/locks that gate in place.
Luckily, the lock staff were able to lower the chamber so that the Kawartha Voyageur could be safely brought down and allow the passengers to exit the boat. Fortunately there were no injuries or damage to the boat immediately reported.

Here's an overhead view of the lock I took when visiting back in 2018;

Now that the Parks Canada crews have been able to do some preliminary repairs, it has been announced that 'modified lockages' will resume on September 26th. Parks Canada announced the following:
" . . .the Lift Lock has been approved to offer limited, single-chamber lockages to vessels returning to their home ports that cannot be trailered. These modified lockages will be conducted beginning on Monday, September 26, 2022, and delays experienced by boaters will vary depending on the position of the Lift Lock chambers when the boater arrives. Boaters (and pets) will be asked to disembark their vessels while the transfer is underway. Still, access to washroom facilities and shelter (in the case of inclement weather) will be made available. Vessels going up will experience a lockage time of approximately six (6) hours, while downbound vessels will experience a lockage time of approximately 30 minutes. . ."

Hopefully the full repairs can be completed before the start of the 2023 navigation season. Will be nice to visit this spot again next year;
