Thank you for the welcome and replies,
I am told 200 grass carp was added to the pond in 2014 in an attempt to rid the summer algae,
The research I have found suggest 7 carp per acre x 11 acres 77 total so yes any aquatic vegetation has been depleted.

Normally the water is clear enough to see 6-10 ft deep just rock bank with sand bottom then the bottom drops quickly to 15' + Lots of LMB, bluegill, sunfish patrolling the shoreline.
While I am fishing for LMB and I do see may 2 schools of 12 or so in the summer most are close to 3' long , I have been feeding them some bread from my dock and then wrap a slice around a topwater lure to catch and remove them slow process. But fun!
I have never seen a bullhead in the pond we do have a few maybe a handful of flathead catfish 10-12lbs avg.
I am going to try the jar test that Rainman has suggested.

esshup,
I will keep a lookout for a moving periscope. lol that had to be a site to see.
We have do about 20 Mallard ducks they are wild and beautiful , but they are a demise to any newly planted vegetation.
I wish I could get rid the carp and then find some type of bottom grass that we could grow from seed.
Thanks again,
Tom Ryan
