As I recall and without looking at the data, the brownish pond (Mu Pond3), had a bloom when I analyzed the phytoplankton. The bloom was comprised of species with darker colored chlorophyll and pigments rather than those species with brigher green hues. There is probably a unique micro nutrient and/or dissolved substance combination in this pond that favors the browner, darker colored species of algae. I analyzed water from one of Ray Scott's ponds that had water chemistry that produced a bloom with a reddish hue.
