Anyways....are there ways to remove millfoil once it is introduced....or is that a done deal?
Right now they are in the process of trying to find out if Cultus Lake has a native weevil (may have already found out, been about 2 months since I was working there).
If the lake does have a native weevil, they will most likely go ahead and culture a whole bunch of them and release them into the lake.
Basically the weevil attacks the new growth on the plants and stops them from growing causing them to die.
Once the milfoil is gone the weevil dies off or goes back to original population sizes.
This has worked in many other heavily infested lakes and has not wrecked the ecosystem, hopefully it can work up at Cultus too.
