So this is a very interesting and (IMO) a huge issue.
When I met with Mitch Leninger last year regarding golf course maintenance, I casually mentioned this to him. It is NOT within Mitch's purview, but having dealt with this situation for many years at golf course, I brought it up, as there's some interaction between golf course maintenance and pond/impoundment health.
(I'm going to use the words "ponds", when talking about the various areas of TV that hold water).
Ponds need consistent movement and aeration, to remain "ponds". Without movement and aeration, the can become choked with aquatic growth and at some point, almost completely atrophy and at the worse produce excessive methane gas.
From a more simplistic viewpoint, the increase in aquatic growth, changes the value of the ponds as wildlife habitat and water impoundment areas (marshes support different flora and fauna that open water). That's not to even mention the aesthetic degradation.
The pond on the approached to the 17th green at TDS has been choked off considerably, since I started playing there, 4 years ago. Just a guess, but I'd said that area has lost at least 30% of its "open area".
The ponds at Palmer seem to have lost at least 30%-40% of their "open water". Lake Sumter seems to be closing in on becoming a "swamp". The boat trips now go out to the middle and travel around in a little circle.
I don't claim to be an expert on ponds or water impoundments, but do have a reasonable amount of experience with drainage and wetland activities. That said, I think this is going to become a huge issue for TV in the very near future. Keep in mind, this is a District issue, as they maintain the drainage appurtenances. Those pesky "maintenance fees" people have been talking about, will be at issue.
There are generally 3 things (that I know of) that adversely effect drainage impoundments: 1) increased nitrogen (fertilizers), 2) lack of aeration, 3) lack of movement (which relates to 2).
What can be done? Again, not trying to be an expert, I just know a little.
EVERY culvert, drainage swale and pipe in TV should be subject to a regular maintenance schedule, to keep them clean and free-running. That's imperative. The volume and velocity at which water runs through a pipe is calculated based on size, hydraulic head, surface type of the pipe and a few other things (Manning's Equation). Once even a small amount of debris, weeds, growth, rocks, whatever becomes stuck in a pipe, swale or ditch, the water velocity slows down. 2 things result. Potential erosion and the drainage system no longer functions as designed, because the water isn't running fast enough (not enough nor fast enough movement).
The other thing that has to be done, is we have to work harder at preventing nutrients from entering the water impoundment areas. Fertilizers, particularly.
I think TV should immediate start removing aquatic weed growth from the ponds. There are company that specialize in this and somewhere you may have seen "weed harvesting" boats, pulling weeds out of shallower ponds (the more shallow a pond is, the harder it is to keep free of aquatic weeds).
Everyone who golfs, has seen "fountains" blowing water in the middle of golf course ponds. They are NOT there for decoration. They are necessary to aerate the water and prevent stagnation.
The Villages has one of the most sophisticated drainage systems I've ever seen. It's huge, complicated, expensive ... and in my opinion, not being properly maintained. This could very well become the next big expense/maintenance boondoggle in TV.
This is an interesting and important subject. I'm thrilled someone has actually brought it up, because it's been on my agenda for discussion since last year. I even wrote a letter to send to the District about it, but didn't send it as I was more focused on golf issues. BTW, if anyone is interested in taking up this cause with the District, I'm all in and willing to help in any way i can. This is a huge and important issue.
For anyone who would like some professional information about the subject, this a good article to read. I recently posted it on X, when a discussion of irrigation ponds was raised ("CountryClubSnob [Eldricks_hoes]" was claiming that the inclusion of "fountains" at golf courses, reeked of "phony prestige", not understanding that they are indeed a necessity.)
