40 years ago you drowned minnows in buckbrush and willow trees that were everywhere... that stuff's not there anymore. 40 years ago you couldn't walk across the two biggest draws for crappie bays on the fishing boats without getting your feet wet. 40 years ago the water was nowhere near as clear as it is now.

I don't know that the numbers are any different now than they were then... but the lake has sure changed a bunch since then.
