fishindude12,
A couple of things come to mind from your description. First, if possible get those areas that have bare ground around the pond covered in grass. That will help some with the cloudy water. Second, like roadtrip said get a water/soil test. In our area of East Texas, most ponds need lime...generally about 4 tons per acre. If your pond had been managed before, then maybe it already had lime applied, but the effect could have worn out. Lime lasts about 5 years in our soils.
Another thing you should try is to get a five gallon bucket of pond water. Let it sit for a couple of days. If the water clears and settles out, then your cloudy condition is due to suspended clay particles from run-off. If it stays cloudy, then you probably have ionized charged suspended matter which will need to be treated with something to neutralize the charge in order to get clearing.
Some things that work for that include gypsum, alum, and ag. lime. You could find some gypsum and add it to the 5 gallon bucket until the water clears and get a reading on what it would take to clear the entire pond. I don't like alum myself because if used improperly it can kill your fish by changing the ph too fast.
I've had that same condition many times in East Texas ponds, and if you are patient. it will almost always clear within about 4 to 6 weeks with the proper additon of agricultural lime.
This time of year with all the rain, most ponds in our area are somewhat cloudy...so remedies you may try right now may take a little longer than they would in summer. Also, if you have a high population of mature catfish, you can expect to have cloudy water, especially if they are not provided artificial feed.
I'm curious about "The striped perch". Maybe you could post a picture? I suspect they are coppernosed bluegill which when feeding show those lines you mentioned.
One last thought, as those large cats get more and more mature, they become the top of the line predators in a pond and generally the bass fishing suffers as a result...but if that doesn't matter to you, then don't worry about it.
If true (and you know how fishermen are) a 13 pound pond raised bass is quite an accomplishment and is not done generally without management. Somebody has been doing something right, again if true.
Personally, I don't like electro-shocking of ponds. I've had it done and would not ever do it again. I prefer fishing the pond to really find out what you have augmented by trapping.
Your BG will tell the story of the status of your pond. The size distribution and condition of the BG reveal what's going on in most ponds.
One thing about "free" pond advice that I have learned the hard way...get your advice from someone who is local to your area, who understands the dynamics of your environment. Some good folks in "Yankee" country will give lots of advice, but East Texas is a lot different from other areas of this great Country and even other areas of our great State.
Enjoy your journey with ponds...it's a lot of fun and very rewarding.
p.s. down the road some, you may want to consider removing trees on the dam.
