The zebra mussel issue presents quite the conundrum. It seems that
every report I see, from the Muskegon becoming gin clear and healthy
to your latest report from the ponds of Nebraska, that the affects of
water purification through the filtering of our little mollusk friend,
is beneficial except that it clogs pumps and other intakes. If this is
all there is to it, this seems solvable and not a bad trade off for
the benefits derived.

So, what are the other bad 2nd order affects of the zebra mussel?

It is impossible to catch and release a wild trout.

Another problem not mentioned on that site is the proliferation of certain
algaes that used to be held in check by limited available light in turbid
water. As water clarity has "improved" some of these have bloomed, leaving
enormous quantities of stinking, rotting vegetation along the waterfronts
throughout Lake Michigan. Presumably, the other Great Lakes are similarly
afflicted.
