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

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.

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.

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.” Continue reading →

Comments Off on Lake Treatment and Survey Report – July 21st, 2016

Lake Treatment and Survey Report – July 21st, 2016

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.”

Comments Off on 2016 Lake Treatment Notification

2016 Lake Treatment Notification

Truesdale Lake Property Owners Association (TLPOA) and Truesdale Estates Association (TEA) will continue the Lake Management Program for Truesdale Lake in 2016. The Program is intended to control pondweeds (Potamogeton crispus and P. foliosus) and algae, thus improving water quality conditions as well as the recreational and aesthetic value of the lake. We hope to bring a more natural balance to the lake in 2016 by reducing the herbicide treatment allowing a moderate growth of pondweeds in an effort to offset the significant algae growth we have seen over the past few seasons.

>Note: Mark June 16th as Lake Management Day:
> – 7-8pm TLPOA Annual Meeting (TLPOA Members only please)
> – 8:15 – 9:45pm presentation at South Salem Presbyterian Church on Lake Management status – all lake residents welcome

The Program is being carried out by NYSDEC certified personnel from the lake management firm SÅŒLitude Lake Management, (formerly ALLIED BIOLOGICAL INC.), registered with the New York State Department of Environmental Conservation (16506). NYSDEC permit applications will be submitted requesting approval for the application of the herbicide Aquathol-K (endothall) and the algaecide Copper sulfate.

Treatments are anticipated to occur between April 1 and August 31, 2016 and will proceed only after the issuance of NYSDEC permits and authorization from the Client. Aquatic pesticide applications will only occur if sufficient aquatic vegetation is present to warrant treatment and favorable weather conditions exist. Prior notification of the exact dates of treatment will be provided to the Association and NYSDEC 7 days prior to treatment and by shoreline posting on the day of application. Water use restrictions are as follows: Continue reading →

Truesdale Lake – End of Year Report

Allied Biological issued their first of a kind end of year report for Truesdale Lake.

It summarizes the state of the lake and the treatments made to the lake. It’s a quick read and a good reference. Hopefully they continue producing these annual reports. Continue reading →

Lake Manager Talk December 10th at 7:30pm

Forwarding a note From David Sachs via Next-door Truesdale website:

“Good afternoon on this overcast and damp and chilly December afternoon. Just a quick reminder – Michael Martin from Princeton Hydro will be speaking tomorrow evening – about lake management in general and Truesdale Lake in specific.

We will begin at 7:30 promptly and will end, I would assume, about 9 or 9:30. Michael has managed lakes for 30 years, and has a lot of interesting ideas to share. Some are similar to things you have heard before, and others are new and different. Come and join us if you can.”

Truesdale Lake Treatment Update – 2015-07-30

Note from David Sachs, TLPOA President:

Good morning to you all. As many of you know, treating the lake is a complex business, and sometimes we are unable to treat it even when we are ready, willing and eager to do so. After the treatment this past Tuesday (July 28) was cancelled, we conferred with Allied Biological – the firm that manages the actual treatments – and also with the NYSDEC to get an expedited treatment for today. After many phone calls between Allied, NYSDEC and us, expedited permission was granted (usually you have to wait a full week, or sometimes two, between treatments). Allied was supposed to treat today – and we took a number of Secchi readings (indicators of lake clarity) to help. Allied had someone here on the lake at 7 a.m. this morning. Sadly, here is what we were told:

“Jeff was on the lake at 7:00 this morning. Secchi measured at 13 inches (too low) throughout the lake and the dissolved oxygen reading was 16 (too high). Treatment cannot be conducted at these measurements. NYSDEC has been notified that the next visit is scheduled for Tuesday 8/4.”
