Here is a couple of paragraphs from an article about rivers which suggests
that hatches and sluices are perhaps the same thing or that at least they do
the same job. A river warden writes:-
"Opening a main hatch six inches drops the level of the river by an inch and
a half, but if that same hatch is blocked, the water will rise at an
alarming rate. Maintaining a constant level is a continuous game of open
this one, close that one, with the river levels changing all the while. It’s
no so bad in fishing season, but during winter floods the hatches have to be
monitored twenty-four hours a day. One pint of Guinness too many, forget to
open a hatch and, oh bollocks, I’ve just flooded Romsey.
All sorts of rubbish and debris come down the river during flood and the
hatches can block very quickly, and frequently do. I’ve had some strange
things caught in the hatches and in the pools behind them. Telegraph poles
are a favourite, as are life buoys, and the ever-present traffic cones. We
get a seemingly endless supply of balls: footballs, tennis balls, beach
balls, rugby balls and hockey balls—loads of balls. Lots of fly boxes come
downstream along with hundreds of floatant bottles"

Could anyone please enlighten me as to the exact meaning of the term 'hutch'
in the context
of 18th century water power? Also, was the term 'penstock' used at that time
for just the
trough immediately spilling onto a wheel, or might it be also used for a
longer section of
raised launder running from the dam to the wheel?
Thanks!
Tim
