Since I made the previous post, I will comment. What you say is true about the hybrids but as long as the forage population is sufficient, everybody is happy but if anything should happen to the forage, that can be disastrous to the fishery (just take a step back and consider NO milfoil). I know of another 500 acre lake where herbicides were used to kill the milfoil, it worked but the alewife population was destroyed thus limiting fish size.
Although the grass carp may be a viable solution in some cases, people may go overboard with the stocking and put in too many carp to control the problem. In this area there are many man made lakes that may lack structure and the milfoil may be the only natural cover for fry, destroy that and you may have a big bowl with a declining fishery because the alewife fry have nowhere to hide. There are other solutions such as milfoil weevils that are indigenous to the area but they help to control the milfoil but not completely destroy it. This may not be the solution in lakes the size of Hopatcong or Candlewood (only started stocking GC a couple of years ago) but keep your eyes open and proceed with caution since it's next to impossible to put the genie back into the bottle (especially if some can reproduce). I'm sure many boaters and swimmers would love a weed free environment but is that good for aquatic life and fry?
