Use a Fa Rake. It takes much of the work and time out of the chore...

The FA rake made from a landscaping rake, pool noodles, and some rope is the best way have have found to remove it from the pond. Throw the rake out into the FA mats with the rope around your wrist or ankle and then pull it back. There is no sense throwing really far, just 20 feet or so. As you drag the rake back in (rather slow), the FA further out will kinda follow the rake in so that it will be closer for the next throw. Also, take some 5 gallon buckets and drill about twenty 1/2" holes in the bottom. I used this to put the FA in at the shore, squish it down to de-water it so that it can be taken elsewhere. It's amazing how much surface coverage fits in a bucket. I utilize the wind to push the FA to one side and get what I can, then check daily for it to congregate again. Of course my BOW is small and I've only had a couple small outbreaks.

Here's my rake...
