March 2020 generation was 12,137 kWh
At 07:00 this morning, Sunday 5th April, the hydro was not generating.
The hydro stopped automatically at 6:30 pm on Friday 6th February on a falling river level to maintain flow through the fish pass in accordance with our abstraction licence.
The hydro restarted at 8:30 pm on Saturday 7th March on initially a gradually rising river level. At 5 am on Sunday a sudden increase in upstream level of 550 mm was accompanied by an increase in generation from 20 kW to 36 kW. The river level is continuing to rise gradually.
On Sunday 8th the early morning surge turned into a gradual decline. However on Monday morning 9th, the river level is showing signs of recovering.
By midnight on Monday 9th the river reached a peak of 1.29 m above crest level. Another peak of 1.18 m was reached at 1 pm on Tuesday 10th. Up to Friday 13th the river has been fairly steady enabling the hydro to generate at a consistent rate around 36 kW.
After a steady decline, from 05:30 on Sunday 15th and following heavy overnight rain in the catchment, the river depth over the weir crest rose to 1 metre.
After declining steadily on the 16th, on Tuesday 17th at around 4 am the river rose to 630 mm over the weir crest. The level then declined until 2:30 am on Wednesday when it rose to 1.2 m over the weir crest before gradually falling to 700 mm at 7 am.
20th March - River level continues its gradual decline while the hydro's automatic control system monitors flow through the fish pass, maintaining it at the level required under the terms of our abstraction licence, to allow upstream migration of salmon and trout.
21st March - The hydro stopped generating automatically at midnight on Friday 20th March on a falling river level to maintain hands-off flow through the fish pass in accordance with our abstraction licence.
