Cover... not much in the main part of the lake.
I left all the timber standing up one creek.
It is about 60' wide 10' deep in the middle maybe 1/2 acre.
I put two large brush piles out in the middle of the lake that is 35' deep. i added 16 of the store bought balls with pvc sticking out around the lake in about 6 to 8' of water.

The sides are really steep. I damned up between three large hills I would guess around a 45 degree slope on most of the lake.

The fish were maybe 2" long

Not sure on the chemistry.
I put 40,0000 pounds of lime down before it filled up and a fellow comes 3 or 4 times a year to test the water and fertilize
