Lumb Bank
Lumb Bank is a private site on Colden Water that has the potential for a great scheme. With a significant head and good flow, the scheme could be capable of producing over 20kW consistently. The area around Lumb Bank is typical of the upper Calder Valley - steep sides and fast flashy rivers, with of course old mill remains all around.
Now that we have Low Flows, I'm aiming to produce flow information and flow duration curves for each of the sites.
In numbers, the flow looks like this:
Period Ntrl Qmean (m³/s) Ntrl Q95 (m³/s)
Annl 0.336 0.0380
Jan 0.527 0.0853
Feb 0.404 0.0745

Apr 0.288 0.0538
May 0.179 0.0380
Jun 0.122 0.0271
Jul 0.161 0.0321

Sep 0.257 0.0326
Oct 0.391 0.0430
Nov 0.467 0.0661
Dec 0.574 0.0971
The flow duration curve looks like this:
