Yeah, the year we tried boulder it was a foot or so low, I bumped a couple boulders but nothing damaging. Somewhere I saved a side imaging picture that was a good example of why it’s called boulder lake.
ya it is an absolute mine field right in front of the public access on Boulder. Once you get beyond that part and out towards the main lake, it is pretty manageable to run around on plane. But if you are unfamiliar with the lake, I would be very cautious going out from the launch, even when the water levels are “normal”. The first few times I took my boat out there, I only ran the trolling motor in that first part – didn’t even lower the main motor until I was in the clear.
