Goose Management 2021 Program Status Update

We have six volunteers who are managing the Fish & Wildlife Service permit that allows us to control the Canada Goose population on Truesdale Lake.

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)

Pirate Island nest with watchful pair checking our activity.

These are the nest and egg counts to date, listed by island from North to South:

Waxwing Island (northernmost island):

3/31 visit – 2 nests

  • W1 north 2 eggs
  • W2 east 0 eggs
  • 2 total eggs 3/31 visit

4/7 visit – 4 nests

  • W1 N 7 eggs
  • W2 E 5 eggs
  • W3 W 5 eggs
  • W4 E 1 eggs
  • 18 total eggs 4/7

Ant Island (middle island):

3/31 visit – 1 nest

  • A1 southeast 3 eggs
  • 3 total 3/31 visit

4/7 visit – 2 nests

  • A1 E 6 eggs
  • A2 W 2 eggs
  • 8 total eggs 4/7 visit

Pirate Island (southernmost island):

4/3 visit – 3 Nests:

  • PI-S-1: 4 eggs – south edge of island
  • PI-W-2: 4 eggs – west edge of island
  • PI-W-2: 5 eggs – west edge of island
  • 11 total 4/3 visit

4/11 visit – 6 nests: (3 existing, 3 new)

Existing nests from earlier visit:

  • PI-S-1: 3 eggs (minus one from earlier visit)
  • PI-W-2: 5 eggs (same as earlier visit)
  • PI-W-3: 3 eggs (minus one from earlier visit)
  • PI-NE-4: 3 eggs – northeast edge of island
  • PI-N-5: 6 eggs – north edge of island
  • PI-CE-6: 6 eggs – center of island (not near shoreline)
  • 26 total 4/11 visit

Summary as of 4/11 (islands listed from north to south):

  • Waxwing: 18
  • Ant: 8
  • Pirate: 26

Grand total as of 4/11: 52 eggs

Feathered nest of 5

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.

Truesdale Fishing Rules 2021

Truesdale Fishing Tag Application link

Lake Members:


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.

Link to 2020 Fishing Survey and results:

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,, 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

Comments Off on 2021 Canada Goose Control

2021 Canada Goose Control

We will resume actively oiling goose eggs on the three big islands of Lake Truesdale for spring 2021. We do this to control the population of Resident Canada Geese on the lake.

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.

March 26, 2020 on Pirate Island (southernmost island) mama goose guards her newly laid half-dozen eggs.

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 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.

What is egg oiling?

Egg oiling is a long-term strategy that reduces the number of resident Canada Geese on Truesdale and other lakes through 1.) physical intervention and 2.) behavior changes.

Physical Intervention

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.

Behavior Change

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.

Oiling Results

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.

We have gotten it much more under control relative to those days — but we can always do better. Will you step up to help?

Ice Safety Tips

With ice formed over much of the lake and deep cold overnight temps over the last week, weekend ice skating might be a thing this weekend for the first time this year!

Before venturing out, check the ice safety tips on the website here.

Always go with a buddy and tell others where you are going. Places where the water flows underneath tend to have thinner ice. Also closer to shore ice is also thinner. But these are guidelines and not always perfectly true. Exercise caution always — and note where residents have placed rescue ladders.

From the TLPOA Winter 2021 Newsletter with a handy guide to making an ice-thickness measuring device. (click image to view full newsletter)

If you go out – take photos! Send them to and we can post them here. Or if you are an instagram user tag them with #truesdaleskating #truesdalelake and mention @laketruesdale.

The History of Truesdale Lake – The First 100 Years

Lake resident Priscilla Luckow has completed a years-long research project into the history of Truesdale Lake.

The document she produced is now available on the website here and can also be downloaded as a PDF file here.

The story of the lake has many twists and turns. Priscilla has also included historic photographs and scans from the original sales documents for the TLPOA and TEA predecessor corporations.

Set aside a few minutes and read up on the lake’s history.

Comments Off on Some Lake New Year’s Resolutions for 2021

Some Lake New Year’s Resolutions for 2021

Some Lake Stewardship Resolutions:

  1. I will get my septic tank pumped and inspected. If the tank baffles are missing or damaged, I’ll have them replaced. (Wind River, formerly Kaiser-Battistone offers 15% discount for lake area residents – but you have to tell them about the discount!)
  2. I will “overseed” my lawn rather than spread fertilizer or pesticides. I’ll tell my lawn service – or myself – to cut my grass high and leave the clippings on the lawn. If I think fertilizer is needed, I’ll use phosphate-free fertilizer since it’s the law. I will also tell my lawn care company that it is illegal in Westchester County to use phosphate based fertilizer unless extensive testing has been done on the soil – and even then only on a limited basis and never within 20 feet of the lake.
  3. If I live on the lake, I’ll plant a “buffer” of native plants to slow the flow of rainwater or stormwater (and the pollutants and nutrients it carries) into the lake. I’ll pull up some invasive plants and plant some native ones.
  4. I’ll pick up after my pets and throw their poop into MY OWN trash.
  5. This year I’ll make sure no oil or gas from my mower or car spills on the ground or into the lake.
  6. If I take coolers, sand toys, or other beach or boat items to another waterbody, I’ll make sure that they are free of weeds and shells before bringing them back here so I don’t transport invasive plants and animals.
  7. If I visit the association beaches and boat launch properties, I will leave them in better condition than when I arrived. That includes putting all beach toys away and removing trash.
  8. If I fish on the lake, I will clean up my fishing tackle, monofilament, and any hooks that get snared. I will not fish in areas where fishing is prohibited (all beaches and the dam/spillway near the siphons). I will not leave fishing equipment, debris, or garbage around or in the lake. It does not disappear and it kills birds, turtles, and other wildlife.
  9. If I haven’t done so already, this is the year I’ll take a safe boating course.
  10. I will make sure my Truesdale Lake boat sticker is still affixed to all of my boats. If any have come off I will replace them. If I have new or unregistered boats I will register them and get a sticker. This applies for boats stored on private lakefronts as well as the boat launch properties.
  11. For when the lake is frozen if I have a ladder I will keep it close by the lake in case an ice rescue is needed.
  12. I’ll start or use a compost pile (away from the lake shore, wet areas, or streams).
  13. If it’s icy, I’ll minimize my use of salt by using kitty litter or sand where I can.
  14. I’ll learn more about my lake’s history, health, plants, and animals this year.
  15. I will send photos I take around the lake to us here ( or tag them #truesdalelake on our Instagram page so everyone can enjoy!
  16. I will join and volunteer with my lake association and make my voice heard and my energy felt during this coming year.
  17. I will try out sailing in the Truesdale Sunfish Fleet #27 this spring and summer. (Sunfish are available to borrow from lake residents if you’d like to give it a try – contact us ahead of the Sunday races and we can figure it out.)

Happy 2021 to all!
