Horseshoe Pond question

One of my wife's cousins is looking at a property for sale on Horseshoe Pond (it connects to the Deer River Flow) and asked me what I know about the summer water condition or recreation quality of the pond. I couldn't say; have never paddled it. Yet I know it is a small and shallow pond, and is probably "nutrient rich" due to septic leakage. I suspect it must get fairly clogged with milfoil in July and August. Does anyone here know?

Thanks.
