In steep hills, the smaller diameter, taller height coastal species

the mill. The slouse is gone, the mill and the big barns is still
there.

i think the word is sluice not sure though

"Sluice" is the correct spelling, but loggers on the
West coast would not call it that, they'd call it a
"flume" (having picked up both the name and the design
from the gold miners).

Flumes were more commonly used to move rough-cut lumber
from the sawmill to a finishing mill, than they were to
move logs. Some of them were large enough to float a
small boat, and the lumbermen would knock together crude
boats from the rough lumber and ride down when they had
a day off.

Googling for "lumber flume" should get you some pictures.
