The canal is about 800 meters long. A portion of the upper canal that had grown in has been cleared. You can see some of the lower section pictured below that will also need to be opened back up.
The above picture shows what about 8 years of growth looks like. You can see the mature roots and then the flat expansion of the new growth that needs to be cleared back.
This is a feeder stream into the canal. Its not quite halfway but makes for a good boat passing and turn around spot.
The above pictures are some of the old growth along the canal. Unfortunately there isn't a lot because people used to use the old stream for access to cut lumber.
