Fish Tables, that is halved lengths of cord timber re-barred to the river bed, seem to have fallen from grace and I wonder why that is? To my knowledge they were first detailed in Hunts’ Trout Stream Therapy in 1993 and were being recommended by the GCT in 1997 but haven’t been mentioned since.
On rivers, where the banks do not under-cut, we find they create excellent holding spots when laid along steep margins and in shorter lengths, where weed is in short supply, they provide refuge for spooked fish in mid-channel.
Here is a photo of a willow trunk, sawn and hewn with wedges, with two potential tables, ready to be drilled, floated into position and propped up on full round non-treated fence post stubs before finally being re-barred to the river bed.
