Truesdale Lake Update – December 2016

Sharing this note from David Sachs, TLPOA President, about results from some testing and lake plans for next summer. More to come in regular updates:

Truesdale Lake Update – 2016-12-29

Greetings and Happy Hanukah and Merry Christmas to you all. I hope that you are having ample time to spend with friends and family and food this week and..

I wanted to provide you all with a quick update about Truesdale Lake and plans for this coming summer – even though there is currently a lot of ice on the lake.

  1. First of all, the copper study that was mandated by NYS DEC has been completed by Pond and Lake Connection. They took 26 samples from the lake bottom, and then sent all of the samples to a lab for testing. There were several sites that had readings that were higher than those recommended. Now everyone (including the DEC) is trying to figure out what the implications (if any) are. They have not ever required such testing before, so it is definitely a “work in progress”. We will let you know more as we learn more.   And, one thing that we do not yet know, is if the new attention to copper might impact permissions to continue to use copper sulfate treatments.
  2. Second, Pond and Lake Connection has completed the necessary permits for treating Truesdale Lake for summer of 2017. They are to be submitted to NYS DEC during the first two weeks of January, 2017 about three months prior to their intended use.
  3. The first permit is for the use of Clipper, an algaecide that is used to kill weeds. It is described as follows: A contact herbicide, the active ingredient in Clipper, flumioxazin, has demonstrated in research trials fast-acting control of aquatic weeds such as cabomba, watermeal, water lettuce, duckweed and, as part of a tank mix, hydrilla. Clipper, which worked best during the early-growth stage of most weeds, also has shown promise for control of some species of algae. Because studies show Clipper dissipated quickly from the water column and did not accumulate in the sediment, Valent Professional Products research and development manager Mike Riffle said it is less of an environmental concern than other, more persistent herbicides. Studies have also shown that Clipper can be applied to control floating or submersed weeds, providing flexibility to applicators. It is anticipated that Clipper will be used during the April time frame to inhibit the growth of weeds in the lake.
  4. The second permit is for SeClear, an algaecide that will be used to prohibit the growth of algae during July and August. SeClear is basically copper sulfate (58.9%) and other ingredients. It will be used approximately every two weeks, and, as in the past, on an “as needed basis” depending upon weather conditions and oxygen levels and DEC permitting restrictions.
  5. The third permit is for Green Clean Pro – a chemical used to treat for algae – it is really concentrated hydrogen peroxide – works quickly and effectively – but does cost about twice as much as copper sulfate treatments. We have tried this before and it is usually permitted for use AFTER the 1st of September – and also if you have to use a treatment quickly because there is a problem with algae. The DEC does need a 7-day window for treatments – but that is sometimes quicker than the alternatives.
  6. Finally, we are anticipating hearing from Michael Martin from Princeton Hydro during the month of January. He had indicated that he would have a report for us during the mid to late January time frame.

Enjoy this holiday season. Happy New Year in advance.

We will continue to keep you updated about Truesdale Lake during the coming months on a regular basis.

Truesdale Lake Update 2017


Sharing this note from David Sachs, TLPOA President, about the past summer and preliminary plans for next summer. More to come in regular updates.

As of 2016-10-24

Good day to you all on this brisk and beautiful October afternoon. I wanted to bring you up to date about Truesdale Lake – some information about this past summer and then more information about plans for Summer 2017.

First of all, this past summer was one of the most challenging and frustrating in memory. Permits to treat the lake were not granted by the DEC until mid-July – and that was only after we begged and pleaded and cajoled them to approve them. DEC had changed their permitting process – and they did so late last spring – and then it all fell apart after that.

When we were able to treat, we did so – but by mid-July that means that you are treating for algae, since weed treating is normally done in the April time frame. Some people said that the water quality was good – which it was in some parts of the lake – but the south end of the lake clearly was not good – with weeds and algae everywhere. Frustration levels were (and probably are) high.

Weed harvester July 2016

Weed harvester July 2016

For the first time ever, we tried some weed harvesting – in late July, when it became clear that the TEA beach was unusable. Weed harvesting can be helpful, but many have said that it is a lot like mowing your lawn in the middle of the summer; it looks good for a week or so, and then it must be done again. Weed harvesting seems to be a lot like that, at least during the summer, when weeds and algae are actively growing.

All of this has caused a lot of thinking about where the lake is today and where we are going. As many of you are aware, there has been a study underway for the past two years through a partnership with SUNY Oneonta, and Christian Jenne has been collecting lots of information about the lake, and has also been preparing a final report. We have his data and are expecting the report imminently.

At the same time, we have been thinking a lot about having a long-term plan developed by professionals. Towards that end, we have signed a contract with Princeton Hydro to develop such a plan. The plan will have a “short term” (1 year) component, along with a longer term (5 year) component. This should enable us to think more proactively about seeking external funding (grants) and doing things for the lake that might improve the situation. We have been working primarily with Michael Martin from Princeton Hydro. A brief bio of Michael states that:

“Michael has extensive experience in lake and watershed management, agricultural BMPs, aquatic plant and invasive species management, algal identification and control, environmental habitat and impact assessment, wetland design and restoration, and development of environmental resource geographic information systems. He has implemented monitoring and management programs on hundreds of lakes and ponds throughout New York, New Hampshire, Pennsylvania, New Jersey, Delaware, West Virginia, Virginia, and Indiana. He specializes in the statistical analysis of long-term water quality, water quality response modeling and the development of TMDLs and numeric nutrient criteria.”

In addition, we have decided to work with a company called The Pond and Lake Connection, located in Newtown Connecticut. They will do much of the day-to-day work on the lake (primarily because Princeton Hydro does NOT do that). Meaning, they will be the ones who will apply for the permits, treat the weeds (hopefully in April 2017) and then treat for algae during the summer. They bring a lot of knowledge and experience to the discussion. Right now they are testing the lake for copper, in response to a new mandate from New York State that we do that, if we intend to continue to use copper sulfate (which we may or may not do). Their plan is to have our application in to the DEC by early December, so that there is ample time for it to be approved long before we need to have it in place. They also have some creative ideas about how to improve the lake, and we are looking forward to hearing what they are.

In all likelihood, there is no “quick fix” for the issues with the lake. But we do need a plan, and we do need more proactive actions. We might also need some additional funding, which we probably need to begin to think about as well. We currently receive and then spend about $25,000 each year on Truesdale Lake ($15K from TLPOA (150 members); $8K from TEA (80 members) and $2K from non-affiliated individuals (20 members). We are hopeful that a plan might provide some guidance about what needs to be done, and what it might cost to do it.

We will continue to provide monthly updates about Truesdale Lake throughout this coming year, and will hold a meeting as soon as we have more concrete information to share.

Invasive Plants Guide

Screenshot 9:5:15, 4:23 PM-2If you have ever wondered whether certain plants in Truesdale Lake are invasive, this free PDF booklet will tell you. We have a couple of species shown in the book, but fortunately not many.

The book is a project of Michigan State University. It has a substantial listing of plants from in, above, and around lakes. Even though it was written with Michigan lakes in mind, the possible invasive species are the same ones that can be found around the Northeast.

Thanks to the New York State Federation of Lake Associations for making us aware of this fantastic free lake resource.

Available for Download Here.

And please don’t forget to get boat stickers for your boats — it helps to keep the invasive plant and animal species out of the lake by keeping boats local.

Comments Off on Septic Pumping Discount for Truesdale Lake Residents

Septic Pumping Discount for Truesdale Lake Residents

Older (circa 2014) septic tank pumping map.

Older (circa 2014) septic tank pumping map.

We have good news: Earth Care is offering a discount on septic pumping and maintenance to Truesdale Lake area residents (EarthCare was formerly Kaiser-Battistone, both are now part of Wind River Environmental) . Cost for pumping tanks 1,000 gallons or smaller is $280.00 (regular cost is $320.00) with an additional environmental disposal fee and a digging fee. I have attached their Truesdale Lake letter to this article.

A well maintained population of septic tanks and systems in our watershed is vital to the ongoing health of Truesdale Lake.

EarthCare Letter to Truesdale Residents

EarthCare Letter to Truesdale Residents

Westchester County law requires septic systems be pumped at a minimum every 5 years. Septic pumping companies in Westchester have been required to report their pumping activities to the county since 2011. The county now has a list of the status of all septic tanks in the county. At some point this information will be publicly available online in the Westchester County GIS system.

Starting in May 2016 if you have not pumped your septic in the last 5 years, you can be fined starting at a minimum of $200 and increasing from there.


Click above image to view EPA brochure on Septic Systems

Most households need pumping done more frequently than every 5 years. Recommendations are at least every 2-3 years to maintain an optimal working septic system. This is dependent on the number in the household and the size of the septic tank. Many lake area septic tanks are smaller size and need more frequent pumping — some as much as once a year.

A septic system is not something you want failing at your house. It is very expensive ($10-20,000 and up) to rebuild a failed septic system, especially with limited acres to place a new field.

Earth Care included a brochure for septic systems that has helpful information on septic systems. Or you can click on the image to the right for the EPA Septic Brochure.

Contact name and number for Earth Care is Angela Warren at 800-428-6166 ext. 101.

Treatment Report from September 1, 2016

Solitude Lake Management came to inspect and treat the lake Thursday, September 1st, 2016. They were able to do only a partial treatment due to lake conditions. Excerpt of report below:

Water column heavy with unicellular algae.  Elodea throughout the lake. Less filamentous algae along shorelines than previous visit.  South end of lake looks very bad as topped out Elodea and dead filamentous algae are causing stagnant water. Unable to treat this area.

This is likely the final treatment for the 2016 season.

Algae Treatment Report from August 18th, 2016

Solitude Lake Management came on Thursday August 18th to inspect, test, and treat the lake. Since the conditions were favorable (good dissolved oxygen levels), the algae treatment was performed.

From the report (also attached):

Inspected Lake: Observed elodea, lilies, unicellular and floating filamentous algae. Lake conditions similar to previous visit with slightly diminished water quality.

Moderate filamentous algae remains in south end of lake, but over 50% of visible floating algae is dead. It is just sitting on top of moderate bed of elodea (topped out or just below surface). Lake green throughout, but previous treatment seems to have gotten rid of trace blue-green clumps. North lake clear of plants in corner but maintains moderate band of elodea and filamentous algae.

Some of this algae is dead as well, but has no place to drop out because of plants. Copper sulfate applied for unicellular algae control.

Lake Loop in Church Tavern Biathlon Labor Day Monday

2016-08-10 18.35.22Who Will Take The Tankards?” – The sign at the end of Spring Street near St John’s Church has popped up again! What does it mean?

It means the Church Tavern Biathlon is ready for its 6th year! The 7 mile biking portion of the course circles Lake Truesdale in a counter-clockwise manner while the run portion follows a shorter 4 mile course where runners catch a glimpse of the lake.

DSC_5728-X3The South Salem Church Tavern Biathlon, is hosted by St. John’s Church and will take place on Labor Day, September 5th at 9:30am. The biathlon is returning for its sixth year in 2016.

The bike course starts at St. John’s at the corner of Spring Street and Route 35, travels down Spring Street, up Church Tavern road and back down to Spring Street where it backtracks to Lake Shore Drive then Truesdale Lake Drive. The course takes a right onto Salem Lane and then rejoins Truesdale Lake Drive for a bit (right turn) before making a left onto Boway then next left onto Country Lane onto Hoyt over the dam and then up Bouton Street (not Gilbert) up the hill.

Church Tavern Biathlon Bike Course

Church Tavern Biathlon Bike Course

At the intersection of Bouton and Lake Shore the course continues down Lake Shore Drive on the west side of the lake. Bikers make the final right turn onto Spring Street for the last half mile and then transition to the running leg.

The running course is out and back on Spring Street with the Church Tavern loop thrown in again in case you didn’t get enough of the hill the first time around on the bike!

There will be prizesBBQ, and music immediately following the event.


Will you be taking a tankard?

Locally the event supports The Community Center of Northern Westchester. Nationally, it supports Puppies Behind Bars – benefiting veterans with guide and support dogs. Each is a very worthy cause and each does a great job fulfilling their missions responsibly.

To sign up for the Biathlon (7 mile bike, 4 mile run) visit the registration page here: You can register as individual ($35), team relay ($50) or to walk the course ($20).

The Run/Walk participants will be timed this year and will leave soon after the Biathlon start. You still get a medal, free BBQ, and the satisfaction of knowing you helped three great charities.

If you are not planning to run, come out and cheer the runners & bikers on! Or volunteer!

Contact Fred Rueck with any questions about the race ( or if you’d like to become a volunteer, a sponsor, or a booster.

August 4th, 2016 Algae Treatment

Solitude came to the lake and did a survey and algae treatment today. Photo and report below.


From Report:

Aquatic Plants Observed: Elodea, Lilies, Duckweed

Algae Observed: Benthic and Floating filamentous algae, Unicellular

Heavy Elodea throughout almost entire lake with plants at the surface in most of south lake and just below surface along shorelines. Patches of moderate to heavy floating filamentous algae cover approximately 20% of the lake surface, mostly in the coves and along shorelines. Benthic filamentous algae also collecting on the Elodea plants throughout the lake. Water appears very green with unicellular algae, especially in northern end of lake, resulting in poor water clarity. Blue-green algae is beginning to clump up in some areas. Trace Duckweed and Lilies in north end of lake along shoreline.

A Treatment was performed with copper sulfate to combat algae problems.

Lake Treatment and Survey Report – July 21st, 2016

Screenshot 7:30:16, 3:42 PM

Truesdale Lake was treated with Copper Sulfate for algae control on 7/21/16.

From the report:

7/21/16 Treatment and Survey of Lake Truesdale

Observed elodea, white lilies, and duckweed along with floating filamentous algae and unicellular algae. Princeton hydro is working hard with harvester on tracks. I applied copper sulfate to the entire shoreline for floating filamentous algae. There are dense patches of elodea scattered around the shoreline where there are dense matts of FFA colonizing on it. Fragments of elodea floating on the surface of the entire lake. Water is turning green.
