Update:
Pond has a definite greenish hue and no longer looks silty. I have not had a sunny day to check the seechi dish reading but would almost bet it's about 17 inches.
I've removed about 30 bass now from 2 to 4 lbs by hook and line in the last 3 weeks that I sell to taxidermy schools and taxidermists. Still lots of bass. I will be liberating 300 bass from the cages as soon as they reach 10 to 12 inches. (I feed my bass).
