The industrial pipeline used to be a solid pipe above and below ground from the noch intake to Hoquiam and y's to cross the Chehalis to Cosmopolis. The wooden section across Aberdeeen Lake was removed and it flows into the lake and water is then pumped from the lake near the hatchery. I am not sure that water coming from the lake is suiteable for humans and in the summer fish have problems with it.

Years back prior to the dam the Daily World had pictures of Wynoochee being nearly dry below the intake in dry years and a bit down stream the ground water brought back some flows. The dam releases insure that will not happen anymore but if used to full water rights the flows below the industrial intake would not look like what exist now.
