Hudson Valley Stream Conservancy (HVSC) is once again very proud to announce that our intern, Sinduja Narayanan of Briarcliff High School, won second prize at the Somers Science Competition for her work on water quality in the Sparta Brook in Ossining and Briarcliff! Congratulations Sinduja!

This work involved a full year of sampling, sometimes at 4:30 AM in February! Undaunted, Sinduja got the data we needed to show that it is the Ossining branch of the Sparta Brook that is, by far, the more problematic of the two branches. She located specific pipe outpours with extremely high f***l bacteria content, even on non-rainy days! These locations and a year's worth of supporting data was issued as a report to the municipality for mitigation planning.

(In related news, the Village of Ossining sought and received an Environmental Planning grant from the NYSEAC to investigate these, and other Ossining sources of sewage pollution to the Hudson River that may be negatively affecting the water quality at the Louis Engel Park waterfront beach. Thank you Ossining for taking this seriously!)

Congratulations again Sinduja!!

I am pleased to report that the Sing Sing Kill (also known as Kill Brook) in Ossining was once again successfully cleared of trash as part of the 2026 Riverkeeper Sweep.

Hudson Valley Stream Conservancy (HVSC) and Green Ossining partnered with Riverkeeper for the 15th consecutive year, restoring different sections of this important stream each year.

We are deeply grateful to the many volunteers who came out—getting wet and dirty—to remove debris from the reach beneath the historic Double Arches along the Sing Sing Kill Greenway. We also thank Melrose Lumber, Union FG (Union Ornamental Iron Works), and the Ossining Department of Public Works for their generous support.

For those who have not yet visited the Greenway, it offers a peaceful—and now even more beautiful—walk through a dramatic gorge, recognized beyond our community, including its appearance in the Spike Lee film BlacKkKlansman. The trail can be accessed from the Ossining Recreation Center parking lot.

Thank you to all who help care for this local treasure.

Sincerely,
Gareth Hougham, Ph.D.
Pres. Hudson Valley Stream Conservancy

Earthday, 2026. Cold, raining and wonderful. Lots of people came out and stayed despite the harsh conditions. We made some new contacts, caught up with many and got some new volunteers lined up for our summer water quality projects!
Thanks for coming out!
