I am in the process of buying some property with a 15-acre pond on that has been there for approximately +30 years. I have had the water and vegetation tested and her are the results:
Water
Visibility 3.0ft
pH: 6.25 (range of 6.0 � 6.5)
Hardness 20ppm
Alkalinity: 30ppm
Avg Depth: 4.0ft. with a Max depth of 7.5ft
Vegetation
Coottail, Eurasion Milfoil, Bladderwort & variable leaf/Pondweed
The Pond is spring fed, so I plan to just do the best with the water situation as it would seem to be an uphill battle and the Coontail & Eurasion was recommend to be treated in April using Sonar (expensive stuff!). There are tons of Channels in the pond with 7-9 ponders cruising the dock and the owner says that he catches bass, sunfish and crappie but I suspect they are relatively small as the catfish probably need to be harvested.
My goal is to rebalance the pond for bass, but I know that it will not produce trophy bass and perhaps at best 4-5 ponders � I think.
That said I am looking for some advice on whether my goal is unrealistic and am I pretty much relegated to a catfish fry every weekend? No offense to catfishers, but I sure would like some variety. Any help, advise or observation would be much appreciated.

Thanks.
