The nutrients from the stream to lake would help, but it was METROs removal of nutrients that lowered production.

Saw a study from Redfish Lake in Idaho that said if the sockeye run were restored to historic levels that water clarity would substantially decrease.

And a zooplankton hatchery won't work unless the phytoplankton are there to fed on and the phytos won't be there unless the nutrients are in the water.

As has been alluded to, the lake might produce a whole lot more sockeye if it wasn't for all the exotics in there.
