Would catching and removing some of the LMB help with the situation?
I turned my old pond around that was over run with GSF by removing GSF and adding 4-6" BG from my main pond.
I believe my BG have the upper hand now by adding the larger BG.
A similar plan might work for you Kirk B. Only in your case, remove LMB and add larger BG.
