The brand new lake in 1958 doesn't seem like like it tackled the problems that it faced before the deepening to thwart algae and creating a large lake paradise.   

It didn't take long for algae issue to re-emerge just three years later.    

I have to wonder if it was a all just a failed 1950's dream of the future that people have hung onto?  Like the giant shopping malls?   

Or do you think it was all just part of bad forward thinking design?    I am leaning this direction now, with good design, a maintenance free lake could have been had.   But since the lake raising, the south lake bank has had to be repaired and I wonder what the state of the private lake shore properties will be in the future if they are all slowly being eroded at?
