We use 387 km instead of 386 km because that is what we get things to add up to.
Balsam Lake is the highest point in the system, not Rosedale or Kirkfield. Kirkfield is 14.9 m below Balsam and Rosedale is 1.2 m below.
The Kirkfield Lift Lock Chambers rise to one foot below Balsam Lake, the system works when Balsam fills this area in the chamber increasing the weight, allowing it to descend so the opposite chamber to can rise. The chamber coming down must always have more water (weight) for the design to function.
There is no lock 29 as two locks were replaced by one at Burleigh Falls.
Purdey's Mills aka Lindsay aka City of Kawartha Lakes, is a side branch accessing Lake Scugog shores and the town of Port Perry.

Brief History of The Trent-Severn Waterway

The start to finish time line spans eighty-seven years with the systems construction starting in 1833 at Bobcaygeon and finishing in 1920 at Port Severn, three hundred and eighty-seven kilometers from Lake Ontario.

A feat of "Engineering and Perseverance" that is hard to imagine when considering the construction techniques that were available at the time.

The Navigation channel runs a depth of six feet from start to finish. The locks vary in raising the water level some exceptions are; flight locks, the Big Chute Marine Railway with a lift of eighteen meters (58 feet), the Kirkfield Lift Lock with an average lift of fifteen meters (49 feet) )and the Peterborough Lift Lock (finished in 1904) with an average lift of twenty meters (65 feet).

Peaking at Balsam Lake the system takes the traveler 180 meters (600 feet) above Lake Ontario and 80 meters (250 feet) above Lake Huron’s, Georgian Bay.

Standard lock dimensions are one hundred and twenty feet long by thirty-two feet wide. The two exceptions are the lock 44, the Big Chute Marine Railway at one hundred feet long by twenty-four feet wide and lock 45 at Port Severn is only eight-four feet long and twenty-three feet wide setting the limit if you wish to traverse The Trent Severn Waterway from one end to the other.

Two major upgrades were at Big Chute in 1960 and combining two locks at Burleigh Falls in 1968 eliminating lock 29.
