Fighting the same situation on a 12 acre lake in NC. Did a huge amount of hand work last year with some success. Also tried the Aquacide Pellets which in my experience did little or nothing.
Questions on the Ecomazapyr for the experts out there:
1). Our dogs and some swim in the lake pretty much daily. Any safety concerns?
2). Maybe I am just missing it or too inexperienced with all of this, but looking over this thread I guess I do not really understand what ratio to mix. For example, if I am spraying round up on my lawn I buy the concentrate and use X tablespoons per gallon to achieve the desired concentration in my sprayer. What ratio should I use with a large back pack sprayer and the Ecomazapyr?
