In reply to APS: we had nearly record low water levels last year when you filled that bottle on the right. Low rainfall = minimal runoff into the lake = really clear water. We've had a fair amount of rain this year and the lake is at or very nearly full. I'll take a little discoloration in the lake for regular rainfall.
I've seen the boat that's the subject of this thread. It's WAY above my pay grade and not my personal cup of Joe but it was wicked quiet going by our place. To each their own, I'll admit I'd like a ride!
