Lewisboro Comprehensive Master Plan Update

The Town of Lewisboro is in the process of rewriting the Town Comprehensive Plan.

There was no significant mention of the lakes in the 1985 Master Plan or the 1999 update and we believe it’s essential for the new Plan to specifically include the goals of lake communities which coincide with priorities of the Town.

The current survey link is at the main page for the Comprehensive Plan Steering Committee: https://www.lewisborogov.com/cmpsc.

The deadline for responses to this survey is 10/31. This survey is looking for people who are interested in helping represent their area of Lewisboro.

Examples of lake community interests include preserving air and water quality, reducing stormwater runoff, eliminating invasive species, ensuring that our lakes remain healthy, etc. 

The Comprehensive Plan Steering Committee will be compiling data from individual residents instead of from groups. 

It’s important that as many lake residents as possible respond to the first survey in which they would agree to participate in the ongoing process of collecting input as community representatives.

Their commitment will be to help get the word out to their friends and neighbors that this is going on.

I have been asked to reach out to our lake communities and need your help.

Let me know if you have any questions.

Take care,
Rob Cummings
TEA President

Why is the lake green? Late summer lake management.

Welcome to August 🙂 The lake is always some shade of green in (late) August.

This is due to several things:

  • Lack of water turnover. It hasn’t rained in a while, at least not a significant amount that wasn’t immediately absorbed by the dry ground. (this is common in August and early September)
  • The water is warmer because of the warmer temperatures. (August)
  • These factors combined contribute to additional algae in the lake.

The lake will (eventually) cool down, the rains will (hopefully) return, and the lake will turn less green in a week, or two, or three. It depends on the weather.

Most of the time our algae is the green algae type. Occasionally the algae type we see can be blue-green algae (cyanobacteria) which can overwhelm a water body temporarily after an extended heat wave. We last had a potential harmful algae bloom (HAB) in 2013 (see article here). Please let us know (Contact us) if you suspect a bloom of this type on the lake. We have testing companies that can examine samples to determine what is present. We have not had these weather conditions this year and most likely will not as the end of the summer is approaching.

Some other things to keep in mind, in no particular order:

  • We manage our lake, we don’t have an on/off switch for the conditions.
  • Truesdale is a lake, which has natural living things in it. We need to maintain a balance. This is for the health of the lake and the other animals and plants we share it with. 
  • The lake’s “filter” is the land around it. Pavement, lawn, and fertilizer are not good for this filtering system. The more pavement there is, the faster water travels into the lake. The faster the water travels, the more nutrients it brings in. More nutrients = more plant and algae growth.
  • Fertilizer on lawns near the lake or in the lake watershed go directly to fertilizing the weeds and algae. Don’t use fertilizer on your lawn. The best lakeside lawns are the smallest ones. Lawns are monocultures that don’t help the local ecosystem and attract geese to the lake (another source of unwanted nutrients). Please read this article about native vegetative buffers and why they are essential for lake health: https://truesdalelake.com/2016/03/article-link-plants-to-use-and-avoid-when-planting-a-vegetative-buffer/
  • The lake will never be a swimming pool. I think many understand this after having lived here for years, but occasionally new residents move in who are unfamiliar with the annual cycle. They may have expectations of water clarity and plant-free water that are neither realistic nor healthy.
  • Truesdale is a shallow lake. (deepest part overall is 16 feet, with the south end near the TEA beach having a deepest point around 8-10 feet). That means the sun is always able to reach the bottom of the lake. This means the entire 83 acres is fertile ground for plant growth. Plant (and algae) growth is going to happen. We can only affect it a certain amount.
  • Herbicides and Algaecides are not perfect by any stretch. They are effective in the short term, but they dissipate and dilute by their nature. However, they are the most cost-effective solution we have for managing lake appearance and conditions.
  • Solutions other than herbicide treatment can be very expensive (dredging, mechanical harvesting) and would require a steady source of tax-based revenue and a tax district to do on a lake-wide scale. Some smaller scale (i.e beach area, or several household lakefront) efforts that have been undertaken to address specific areas at specific times. These projects funded financially by individual homeowners or groups of homeowners, not lake-wide.
  • Other weed control alternatives like grass carp are essentially undirected biological weapons that give no guarantee that the carp will eat 1.) where your want them eat to and 2.) what you want them to eat. They are also invasive species and must be sterilized before introducing them or they will overwhelm the ecosystem.
  • Even under reproductive control, non-native grass carp can end up decimating the native plant life and allowing invasive plants to gain even more of a foothold if they prefer the taste of the native plants more than the invasives. These fish can also root around the bottom of our lake, stirring up muck and introducing previously buried nutrients back into the water column. This may actually end up causing more problems with water clarity and weed spread and growth. They also cannot be fished out (removed) if they become a nuisance.
  • Everything we do is a trade-off between time, money, and effectiveness. In addition to keeping a balance of nature, we are trying to balance the checkbook.

The bottom line is any solutions we employ are management, not control. We have a limited number of levers to move to affect weeds and algae, and we (and the professionals we hire) do their best in the environment we have.

New ideas and undertakings are always welcome — we are all in this together. If you are looking to do wetland buffer zone work, waterfront work, or lake floor work, a wetlands permit is needed from the town. Please visit their website for more information. Please consult them *before* starting anything since fines can be steep for work done without proper permits.

Full Moon Regatta – Sept 10, 2022

Get yourself and your boat(s) ready. Bring the kids. Bring the lights!

Meet out in the center of the lake starting between 7:00-7:30pm. Sunset on 9/10 is 7:13pm and “nautical twilight” ends 8:13pm (stars start to appear). Astronomical twilight ends at 8:47pm (darkness). The moon is full on this day, so it will rise in the east at 7:45pm and it will start to be visible above the treeline about 30 minutes later.

See you out there!

Comments Off on Summer 2022 Sunfish Sailing Kickoff Weekend Coming Up

Summer 2022 Sunfish Sailing Kickoff Weekend Coming Up

Dear Truesdale Sunfish Sailors and Aspiring Sailors,

Truesdale Lake Sunfish race buoys are out — and the course is ready to go. All we need are sailors!

The typical Truesdale Sunfish Fleet #27 season consists of a 10-week series over the summer and a special one-time race “The President’s Cup” on Labor Day Monday (weather permitting).

We run two races every Sunday starting at 1:30pm from the start of summer through Labor day (Sunday, Jul 3 – Sunday, Sept 4, 2022).

“Preseason” practices were in June to give everyone a chance for a shakedown cruise.

We score the two races and add up only the best 10 races for each sailor, dropping their lowest point races. This means you don’t need to race every week to be competitive, and if you improve during the season your early scores don’t count.

These races are strictly for local fun and challenge — very low pressure. We don’t report results anywhere but here. Beginners and kids welcome and encouraged — and they usually pick it up pretty quickly.

The races starting line is off the dock of 43 Truesdale Lake Drive which is just north of the southernmost island on the lake (aka “Pirate Island”). Look for the pair of blue and white buoys that make the start line. And check the sailing race buoy chart at the bottom of this post.

More information about the series, rules, and scoring is available on the Truesdale Lake website:  http://truesdalelake.com/boats/sunfish-fleet-27/

The Truesdale Sunfish Fleet #27 is one of the oldest in the world. The Sunfish was designed and developed by Alcort, Inc. not far from here in Waterbury, CT.

Truesdale Lake was one of the early lakes that the Sunfish design was tested on before going into production in the mid-1950s. The fleet numbers are sequentially handed out, so #27 is a very old fleet number designation. Current fleet numbers for new sunfish fleets are in the 800+ range now.

Check some Sunfish history in this article: Sunfish at sixty: Most popular boat ever still keeps them busy at Portsmouth plant.

Please pass this on to anyone you think might be interested in joining us.

Many of our regular sailors have extra boats and can lend one out if given enough lead time to get it rigged and ready.

We can also help with beginning sailors pre-race. Please get in touch before race day — and come a bit early to see the start area.

Hope to hear from you or see you out there!

Ira Sanchick, Sunfish Fleet #27 Commodore

We had well over 25 boats out on the lake lighting up the night under the nearly full moon Saturday, June 11th on Truesdale Lake. (The June full moon is nicknamed the “Strawberry Moon” which fit the strawberry shortcake cupcakes served mid-lake!)

Thanks to Lisa Capobianco for organizing and setting up the summer kickoff BBQ at the TEA beach on Truesdale Lake Drive. Many new faces joined in with old-timers at this annual party.

The weather was great and the clouds parted in time for the moon to show up and boaters and floaters to shove off from the launch.

Check out the photos below to get a flavor of what it was like.

Next nearly full moon on a weekend is Saturday, July 9th (the July full moon is Wednesday, July 13th, the “Buck Moon”). Weather permitting we can do a 2022 encore!
