Congrats, Jaymz! That is just outstanding! I fully appreciate the sense of hope and satisfaction that comes with knowing you got one up on such an invasive plant, at least for this season. My best recommendation is that you tackle it proactively next year - hit the pond with another dose of fluoridone before anything starts growing. In my case, late application like yours in the first year followed by early application the next (last year) led to absolutely none showing up this year even though I didn't use fluoridone this year. Best of luck keeping ahead of it - that was one mutha of an infestation you had, bud!
