Once again there has been a landslide in recent weeks above Catrine Dam. This is the second major slide within a year.  The debris at the foot of the bank causes gravel and sediment to build up, shallowing the pool and deflecting the flow to the opposite bank and today I noticed that this too is eroding.

I’m not sure who is responsible for the bank but I’d suggest in it’s current state, it poses a significant risk to the dam with large timber mobilised and washing downstream. I expect that unless some way is found to stabilise the situation, the trash screens at the dam will need constant clearing after each rise in water levels.

The spate today was on the rise when I was there around 2.00pm. It looks as though this will again be a huge flood when it peaks.
