Hi, we just moved to the neighborhood and I've been really curious about the health of the lake so I've done some research and spoken with city and county officials. The lake is actually not owned by the city, per the tax parcel map it is "dedicated to the public". The city official I spoke with last week was very kind and let me know that they are encouraging the homeowners on the lake to care for the lakefront on their property. There is an easement but this only means so they can access stormdrains and the lakefront and such (ie no fences or blockades down to the waterline). We have neighbors with cattails and you're correct, if not maintained they spread quickly. One positive is that their rhizomes/roots are strong which helps stabilize your lake bank section. I plan on looking into native plants that will help stabilize the shoreline and act as a filter for our nutrient-loaded lake. I'd be happy to let you know how it goes if you're interested?

Hello, welcome to the area. I hope one doesn't mind that I'm posting here to add some clarification. I'd take what the city says with a grain of salt.

The lake is a retention pond the city manages. So, a part of that storm water management is vegetation control. For decades, the city sprayed cattails for residents. They still provide this service to other retention ponds. So, from what Carolyn was told, and what the prior commenter said, they are just avoiding the effort, it seems.

The cattails actually do minimal for bank stabilization, I've lived with and around them for years and the shoreline has eroded away the same. The land still washes away, it just goes around the rhizomes and you have the same problem now, just a bigger mess of cattails to clear away as they filled in more and more of the collapsed bank.

The only way to truly control erosion is by making a barrier that stops the dirt/land from washing away-- which is a seawall or a geotextile fabric.

The lake has been degraded for years-- and has been very bad in recent years with the toxic blue-green algae blooms I've learned about...

The hoa has some city data reports here: https://harborislehoa.wildapricot.org/SOLitude-MANAGMENT-REPORTS

I also learned, without putting oxygen at the lake's bottom, to improve the low or nonexistent dissolved oxygen levels there, as the reports show, the lake will always have problems, like algae and high nutrients.

We need aeration at the bottom of the lake, like this...

There's plenty of research online about it... and even the city knows about this type of option, but they have yet to try it out.

The harbor isle hoa has some city data water quality reports online. Without putting oxygen at the lake's bottom, to improve the low or nonexistent dissolved oxygen levels there, as the reports show, the lake will always have problems, like algae and high nutrients.

We need aeration at the bottom of the lake, if you just google "lake bottom aeration" there's plenty of research online about it... and even the city knows about this type of option, but they have yet to try it out.

Has the City considered addressing this issue, or are you just going to ignore it? Thank you.

See.
Click.
Ignore.

It's the new motto & web site for this issue.

I see my property taxes raising each year as I literally see my property eroding into this toxic lake/pond/cesspool.
