As earlier intimated, the Anderson’s Weir was duly opened for salmon migration today. The full river is being allowed to pass through the fish pass and over the new weir crest at Anderson’s. Things looked good to me when I visited after work this evening and I can hardly wait for the next spate to see how the water flows and fish get over it. I’ve nothing more to add to this but the weather forecast this evening is predicting heavy rain for next wednesday….. here come the fish.
The middle pool and the newly reconstructed Anderson’s weir.
The new weir crest looks good. It is at exactly the same height as the previous weir but with the new radius edge, the water holds to the concrete in a smooth flow without all the entrained air. Salmon and trout should now be able to swim over Anderson’s and most of them will probably remain unseen as they can swim from adequate depth below. I suppose time will tell.
Anderson’s from downstream. The wider gap can be seen clearly and this will reduce the velocity of water going over the weir.
looking good been long and frustrating at times but looks the part send on the salmon
well done lads
Aye as Ian said looking good as long as it help’s the salmon get by that mess o. a fish pass finger’s cross . well done use all.
All credit for pulling the stops out goes to the Contractors. Once they realised that we were actually trying to help them, the process moved along without any conflict. They did more than was in the contract in an effort to accommodate my requests and suggestions and I’m very grateful that the site agent understood my concerns. An example of this was widening the excavation in Anderson’s Pool in response to ART’s request and the removal of a 4 tonne lump of concrete that was cracked and would eventually have collapsed, perhaps blocking the gap and leaving us all to figure out who was responsible for its removal. I hope they manage to complete the fish pass extension as a priority because I’m sure they would again come under fire from the anglers if they shut this down in the middle of a salmon run. The sooner they do this, the sooner they will be free of us all and able to complete the encapsulation of the dam without moans and groans from all directions (all justified of course).
