I think my son got some pics of two of them, shells around 6 inches across but generally only see a small head poking out of the water. We're right next to the dam and so look down on them in the water. Tend to be out early morning & late afternoon/evening.
The big lake is pretty full to the concrete sleepers byt the level declined by about a foot in the 3 weeks we were out.
The 164 lake is up and down based on golf course watering, IRM seem to let the water get pretty low before topping up rather than filling on level sensors which can make it look unattractive when the level is low.
All in all the lakes looked good when we were out in August
