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

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.

Summer Squall Chases Harvester to Shore

A late afternoon thundershower chased the harvester back to dry land as quickly as the treads could drive it across the lake. See photo attached. Fortunately better weather is in the forecast for tomorrow.

We have contracted with Princeton Hydro to mechanically harvest weeds using their “Truxor” amphibious vehicle with multiple attachments. See photos for details.

They will be here for the next week+. Work will start tomorrow morning (Tuesday 7/19).

More “action shots” & video to follow once it is in the water and working.

Lake Survey Report – July 13th, 2016

From the report:

7/13/16 Survey of Lake Truesdale

The water column was green with unicellular algae. North of the launch and up along eastern shore displayed Elodea in sparse patches. Denser infestation in the northeastern cove covered with filamentous algae. The northern end by the spillway displayed trace patches. Down the western shoreline, the Elodea becomes sparse to moderate density to the cove area just south of west beach. Then the density increases with moderate patches scattered around the cove.  Past the island, down to the southern end and back along the launch, the Elodea becomes very dense with filamentous algae clinging to topped out plants. The lake center displayed stray patches of Elodea with 90% of the plants topped out.  Water samples collected for algae county. Spoke with Lara Gorton on site. She noted that the lake has been used more this year than compared to last year.
