The TEA will be holding a “moonrise BBQ” at the Truesdale Lake Drive beach starting at 5:30 p.m. and going until around 8 p.m.
Lake association residents are invited to join in – come over via boat if you can and have a burger, hot dog, chicken, or veggie burger as we count down to the full moonrise at 8:32pm. Stop by for an a few hours or a few minutes! Just don’t miss the moonlight regatta.
The permits allow us to addle and oil the eggs to prevent the eggs from developing and greatly reduces the number of Canada Geese on Lake truesdale not only the current year but also in subsequent years as it changes the migratory behavior of the targeted geese.
The mated geese end up spending their valuable incubation time on the nest with intact but non-developing eggs. Then after a failed nesting the geese pair continues their migration to the Canadian Tundra which is their natural summer feeding grounds. (See PDF information for more detail)

We also noted a Swan Nest with 3 eggs on west side of Pirate Island and Mallard Duck nest with 10 eggs in center of Pirate Island. Neither of these nests were disturbed.

As many of you are aware, last year we had a substantial increase in folks who were not members of the associations fishing on our dam and bringing boats into the lake.
This resulted in fishing in restricted areas, blocked traffic, the death of wildlife entangled in snared and discarded fishing lines, and significant amounts of garbage left behind for residents to clean up.
This has led to the unfortunate need to increase enforcement of our private lake rights to reduce the harm to our ecosystem and property.
To keep our lake community and wildlife safe, the boards of TLPOA and TEA have jointly agreed to require and issue a Fishing Permit Tag to association members in good standing who would like to fish on association properties.
There is no cost for a tag. Tag request link is below.
Signs will be installed reminding everyone that this is a private lake and fishing permits are required. These actions were implemented based on the results of the lake wide survey from 2020 and some good old fashioned common sense. The link to the survey results is below.

These steps will help to mitigate the increased issues experienced over the past couple of years and will empower the police to help us enforce the law and rules of our lake if they are called.
Any member can nicely ask the folks using our dam to fish to see their tag if it is not displayed, politely ask them to leave if they are not a property owner.
If you wish to avoid the conversation completely you can contact the boards at TLPOAboard@gmail.com, email@example.com, or call the Lewisboro Police directly at (914) 763-8903.
If any member feels they are fine with non-owners using the dam, just keep enjoying your walk or drive. No one is forced into being a security guard for the neighborhood.
The summary of our rules are really simple…
1 – You must be a member of one of the Lake Associations and required to have your new Fishing Permit Tag with you while fishing on the dam, boatyards, and in a boat
2 – You must accompany any guests you may invite over while they are fishing
3 – No fishing on the beaches
4 – Clean up after yourself

by rob Comments Off on 2021 Canada Goose Control
We have checked the three islands of the lake as of today and we have not found any nests. We will continue to monitor the islands through the spring and act as needed.
Egg oiling requires a permit from the Fish & Wildlife Service (FWS) which we have obtained. Truesdale Estates Association has renewed its FWS RCGR (Resident Canada Goose Registration) permit #13757A and currently there are six residents who are named on the permit.
We can add anyone from the lake community who is interested in helping! See below for more info.
The program on Truesdale Lake started in 2008 and has been very successful in controlling the population of resident Canadian Geese on the lake. The number of geese was in the hundreds in the early and mid-2000s and the oiling program has been successful in reducing these to several dozen in the past 10 years.
In 2019 the program did not have anyone oiling the eggs and the resident geese population shot back up into the 70-80 range – and possibly more. In 2020 we resumed the FWS program and there was only one resident family of Canada Geese on the lake for the summer. (There are frequently transient geese but they usually do not stay long.)
If you are interested in helping out, please contact us via email at firstname.lastname@example.org or via our Contact Form. The process is not too difficult and training is easy. We would need to add your name to our FWS permit before you can be involved with the oiling program.
The physical intervention is the actual oiling of the eggs after mating has occurred but before the eggs have developed embryos. In our lake this typically takes place in late March or early April and can be pinpointed by observing the mating ritual of the local geese couples and finding their island nests about a week later.
Oiling works best with a crew of two or three working together. One person finds the nests, one person keeps the geese away from the nest, and one person oils the eggs. It is possible to do this with one person if they bring along two umbrellas to shield the activity over the nests.
Oiled eggs are marked with sharpies to keep track of which ones have been treated. Records are kept for the number and location of the nests and the number of eggs in each nest as a requirement of permission from the Fish & Wildlife Service.
The behavior change for the geese is the most important long term consequence of oiling the eggs.
We oil the eggs rather than simply break them because if the eggs are broken the goose simply lays more eggs. However, if the eggs are oiled, the development of the egg is stopped by preventing oxygen flow into the egg. This prevents the egg from hatching.
Since the geese do not know this, they sit on the eggs for the 5-6 weeks it takes for hatching. When the oiled eggs do not hatch, the geese view it as a “failed nesting.”
Resident Geese bad, Migratory Geese good
In a successful nesting, the adults shed their flight feathers and take up residence with their new goslings on the lake.
This is NOT the outcome we want.
It is important to get all of the eggs and all nests oiled – or as many that are found. If there are enough goslings in a flock, even other members of the flock who may have had failed nestings stick around and lose their flight feathers to support the new parents in the flock. This creates a resident flock for the entire summer.
In a failed nesting, they keep their flight feathers, take off, and head further south for the summer. They do not have the time to lay more eggs and have the goslings fledge and fly before the end of the season.
This is the outcome we want.
These geese also do not develop a preference for returning to Lake Truesdale next summer and resume being Migratory Canada Geese rather than Resident Canada Geese.
Keeping the geese migratory means the problem is reduced both in the current year and in subsequent years.
Other geese will find and take up residence on Truesdale if we stop oiling the eggs, so we must keep up the program to head off more future residents.
We will also always have transient migratory geese — you can tell these geese since they are willing and able to fly away and visit other lakes since they do not have goslings to protect.
Last year, the crew of egg oilers has oiled over 100 eggs between the three islands. This prevented the hatching of those eggs and has broken the resident behavior of those goose parents. The aim is to not have them return for 2021.
To be successful, there has to be an initial oiling treatment and several follow up oiling treatments. Timing is the key to successful outcomes. New couples appeared and new nests were created after our first and second trips to the islands. Each island ultimately required 4-5 trips.
Egg oiling has made a huge difference in controlling the resident goose population on Lake Truesdale.
When we first moved here in 1999, we would arrive home to 60-80 geese/goslings on our lawn. There was easily double or triple that number on the lake. Lawns were covered in goose droppings. The beaches were favorite spots for goose gatherings. I have photos (deep in the archive) that I can dig up in case you think I am egg-agerating.
