River Coquet Hydropower
With the feed-in-tariffs for hydropower ending in March after little activity over the past couple of years, the beginning of 2019 has seen a flurry of applications for new hydro schemes.
For us, this has once again highlighted the importance of our Riverfly Census data to provide evidence, not just anecdote, on the state of our rivers.
We recently used data from the Census in our response to a hydropower application on the river Coquet.
On this important salmon river, the Census results, which are collected at a higher resolution and frequency than the Environment Agency’s own data, indicate some phosphate, sediment and pesticide pressures already impacting the reach in question.
This, coupled with the Coquet salmon currently classified as ‘probably at risk’ and seatrout ‘at risk,’ surely means we should take a precautionary approach to such developments?
The recent closure of the north east drift nets will be a very important step to improving salmon stocks in this area, but this is by no means a silver bullet.
We must use every opportunity to remove in-river barriers to migration, both upstream and downstream, such as the weir mentioned in this application, as well as improving water quality and salmon habitat too.
The power of the Riverfly Census has led us to develop SMARTRivers – taking the Riverfly Census out to local rivers by training volunteers to sample and analyse aquatic invertebrates to species level, to provide the evidence to drive change.
