The beautiful body of water now known as "Lake Sumter" was originally "Cherry Lake". Here are some pictures of the transformation that occurred when the Developer decided to do so:
1994:
1999:
2003"
2007:
2011:
The point: Paradise Lake can be "fixed". But, the Developer probably didn't have the insight (nor resources) to do it right when it was adopted as a The Villages feature.
Whether it can be "fixed" now is a good probability, on the basis of the transformation of Cherry Lake into Lake Sumter. Whether the resources to do so can be provided is unknown. But, that will not be known unless an enginnering study is performed and a cost estimte provided to allow meaningfull discussions.
Currently there is a mindset by the ACC against any improvements and this mindset has been adopted by the POA. Unfortunately, this mindset is not based on credible findings as would be obtained from an engineering study. Lay persons have presumed to "know" certain physical phenomenon that are as yet unconfirmed by scientific opinion.
