One would expect that even small % algae left, that is enough to completely 'reseed' for next year. So, does this algae kill need to be redone next year and ongoing as a control? If so, probably benefit to the company. Additionally, survival of 'some' and 'rebound' seems to mean they really don't know or perhaps anticipate the result. Either way, I expect DNR had little to say regarding impact to a nice fishery.
Usually, yes, it would be an annual or "as needed" treatment. (although I don't have inside info on the Mantua case)
If the water managers do indeed feel the treatment was a "success", then it could be bad news for Mantua as a fishery as those in charge will likely reach for a repeat treatment every time some algae pops up. It certainly appears that algae issues in general are not going away in our lakes and fisheries.
