YUP:
Kids have been legislated off the lake because they have more than 25 HP..or they are under 16..or their parents won't buy tham a small boat because it's unsafe what with all those GFBLs, .....and whatever other regulations we now have that we didn't have in the past and got along fine without.
How about this.. There must be a brilliant out of work biologist out there who can "Discover" a non native species of Snail or something, that enjoys eating milfoil and cannot survive without it in their diet.
You import the Snail... or whatever it is, and it eats up the milfoil and as the milfoil population is reduced, the Snail..or whatever, dies off because there is no more milfoil..because they ate it up.
SO now the lake is free of milfoil....AND the non native Snail that ate it up.
And the lake lived happily ever after, as it was meant to be. 
OH WAIT: In all this excitement ...I almost forgot: Some "Other" brilliant biologist will put BOTH the Milfoil AND the non native Snail..or whatever, on the
"Endangered Species List" ..... and will then be protected against those
Insensitive People who would eradicate them. .
