Hitting Bottom

I took the kayak out on the dam to test out the water depth. Sadly, it is the first time this kayak has touched Australian waters. Given the length of time I have been living in this great country, it has been far too long. However it was still up to the task and, despite there not being much in the way of white water, it performed quite well.

During the portage from the shed to the dam, I thought about a great Canadian super hero called Mr Canoehead (Canada's greatest aluminum crime fighter). If you have never heard of this mighty Canuk, then it is worth checking out the link to some old video clips.

After launching into the dam, I could not resist "opening her up" (i.e. paddling quickly from one end to the other). It is always relaxing paddling and I look forward to doing this regularly in the future.

After a bit of fun, I used a depth checker to see where the bottom was. Unfortunately, the depth is not quite as deep as I would have liked. It is only about 1.5 m at either end, with the northern end being just slightly deeper. Throughout the rest of the deeper parts of the dam it varies from about 1 m to 1.25 m. So I would say that the average depth of the water is around 1.2 m. Still, given the challenges with all the water while it was being dug out, it is still a good result. But I will see if we can excavate a bit more tomorrow.

I also took the opportunity to plant some of the reeds back around the shallower areas. Hopefully they will take and start filtering the water. I will also need to speak with the folks at the Kumbartcho Sanctuary nursery and purchase some native water and margin plants to put around the dam.

  1. Any thoughts to putting a microhydro turbine on your dam to generate electricity?

  2. Hi Kevin
    No I have not thought about a micro turbine. Mainly because I do not believe that it would be featible due to the short water fall. However I would have to do some more research first.

  3. There are some that work with fairly low height.
    energyalternatives.ca has one that works with 10ft drop but probably needs more volume than you have.
