Anthropic, although the lake needs some help it is actually not a bad fishery. I have caught two largemouth over six pounds this spring even though the majority of fish caught do not show size distribution. The majority of fish appear stunted due to over population. All of that to say I hate to drain the lake and start over. Finances are definitely a factor. My first priority has been to reduce the number of lmb, and restore the forage base and forage habitat.
I may just try adding a few 100 pounds of ag lime to the feeder creek periodically as it washes out or is absorbed. Then in a few months , have another sample ran just to see if t is making any difference.

Thanks for your suggestions.
