Hello all...i am a new member to pond boss as i have only recently discovered it.

My dilemma is our family pond. We always have enjoyed fishing their and have caught some great fish and have some amazing stories from the old pond. About 5 years ago a guy who leases our pasture for his cows spread chicken litter on the pasture to fertilize it. That night it came a torrential rain which washed a ton into the pond. Im assuming this is what caused the fish kill. We ended up with dead fish floating everywhere over the next few days. I found 6 lmb over 5lbs and over 500 eating size bream belly up on the banks. It was devastating to watch. Since then we have the most scroungy starving fish i have ever seen. Everything is horribly skinny. Even with our auto feeder they are still dinky. It used to be nothing to go catch a mess of bluegill the size of your hand for dinner or go have a heck of a time catching nice fiesty largemouth. Now your lucky to catch a bream big enough to fillet or a bass over 10 inches. My dad suggested killing the pond out and starting over. I am here for suggestions and help as what to do about fixing our problem to restore the pond back to its former glory...watching fish break the surface chasing bugs or minnows...not just a stagnant puddle anymore...Thanks in advance for your help and advice...
