Potomac water is eutrophic. That means rich in nutrients.

Put baby algae in a bath of warm nutrient rich water and you unsurprisingly get a huge algal bloom.

I hope the NPS doesn't attempt to use silver carp (which do feed on algae) as a control Or we will have fish jumping out of the pool and assaulting visitors to DC (just kidding, well sort of)
