Here’s the newsletter. If you could distribute this to your contact list for those who may be interested.

We will be dropping the gates at New Mills in order to understand the impacts upstream on Monday 10 Feb until the 12 Feb (lunchtime). The drop will be gradual in order to minimise impacts on fish populations and other river ecology.

The drawdown will actually happen over three days, and not two as stated on the newsletter, due to the tide times and Fisheries advice. The gates will start to drop from Monday morning, stabilise over-night, drop further on Tuesday, again stabilise and the water will be at its lowest point on Wednesday morning at low tide.

Fisheries will be monitoring the situation throughout the trial and will have a fish rescue equipment at hand. We have undertaken an initial scope of the project and highlighted one area of high risk and have a rescue plan in place. Other lower risk areas will be monitored.

Although dropping the levels sounds dramatic, trials of this type have been undertaken at New Mills before with no impact on fish populations. The most recent was done to enable work to be done on the upstream bridge by the Council a few years ago. We completed a similar trial at Hellesdon a few years ago, again with no impact.

Should there be significant unforeseen impacts on fish the trial will be terminated.
