Question #7:
I read a report that said that in 2006 the Quarry Lake was inundated with sago pondweed. It was found in all parts of the lake, in very high density. The association members explored possibilities for eradication. The next three years however, there was virtually no sago pondweed to be found. Speculate on why 2006 might have been such a bad year for this submergent vegetation.
The map at the beginning of the thread was not taken in 2006
Clue above? Here's where my pond ignorance kicks in and kicks my butt! Assuming the repost of Question #7 is to suggest none of us have hit it yet, how about the emergence of whatever that is in the picture snuffing out the growth of the Sago PW? Maybe it's a type of vegetation that does even better in nice clear water than does Sago, and it simply took over, dominated the growing conditions for Sago, and basically did a natural job of eliminating it? I like this thinking out loud bit and the exercise of guessing at the answers, but kills me to wait to see if I'm even on the right track!
