An excellent project. If you are successful it will benefit all the river's wildlife. Keep me informed?

Not sure about the use of existing species being best. If the species were suitable to the stretches you have chosen, would they not already have estabhlished themselves in those areas? It seems possible that totally new species might have a better chance of filling those niches?

The water quality in the Goyt is certainly good enough: look at the prolific streamer weed growth just above where the river meets the Tame. The Tame water quality is probably less good than the Goyt, but the Tame has more areas where the combination of shallow water, gravel and sunshine combine to form a suitable environment. And it does not have the high levels of gravel transit that the Goyt carries in spate. You don't see significant remodelling of the riverbed contours on the Tame. Less moving rocks to rip up established weeds.
