The flow has been at 13 CFS for the last 2 readings, vs the median of 264 CFS -& 25th percentile at 40CFS, granted it is not at the low recorded of 6.5 CFS or '78, bit is way closer to the lowest flow than even the 25th percentile flow, so I'm gonna guess that the flow was not 'normal' on Thurs...
Some posters may not even know that the Wailuku at Rainbow Falls is partially diverted, as there is a Hydro penstock above the falls. During lower flow, water is diverted at 10% of flow rate to run the turbine, and then we only see flow increase when the hydro-power is at max capacity... so all of that river flow increase is not seen by the casual observer at the falls, but there has been no power generation for the time this thread has been alive, as the flow rate has been below 1% volume the whole time....
If HELCO is not generating power there, it is a very low flow rate...not "normal" - as an electric company would never have stated up if it was normal to NOT have electricity from their generation source, and Hawaiian Electric Light Co (HELCO) started with the Puueo hydro-generator....
