When I found the lakes (the hard way) I spent a couple of hours looking for Brilliant Emeralds. They were plenty of Four-spotted Chasers, Downy Emeralds, Common & Azure Damselflies, a probable Golden-ringed Dragonfly, Large Red Damselfly and a few Keeled Skimmers.
I found a spot overlooking one of the lakes where I tried to pick up a Brilliant Emerald without much success. The funniest thing was I was sitting on a dead tree trunk overlooking the lake and suddenly it have way dumping me partially in the lake.
I Kingfisher was noted a few times over the lake.
