Time to start a blog ...

The summer is over, leaves are falling from the trees and rain is also steadily falling from a leaden sky, - all factors I take note of as together they mean ground water will be building up. Soon there will be sufficient gushing from the spring which is the source powering my turbine.  
This start to another "water year", the second year of operation of my turbine, seems an opportune time to start a blog about it.
I need a minimum of 1.2 litres per second (lps) and this morning it was just 0.57 lps.  So some way to go yet. But with the steady drizzle and rain we're having at the moment, the flow should be there in a week.
Yet I have come to learn in its first year of operation that you cannot predict anything. You are entirely in the lap of the weather and being so creates a humble appreciation of the natural world.
Hope and expectation spring eternal nevertheless... the hope being to better the first year's output figures:
