Hudson River Tributaries



Tributaries are the streams and rivers that feed a downstream river. There are hundreds of small streams that contribute water and pollutants to the Hudson. They are vital passageways for migrating and spawning fish.


Tributary Projects:

i.Sing Sing Kill (SSK) :-

Over the summers of 2016 and 2017 an extensive DEC funded study was carried out on the SSK regarding the fish ecology, , the water quality, culvert conditions regarding fish pass ability and the stream hydrology. The SSK is also referred to as the Kill Brook. Eight different species of fish, American eel and crayfish were documented whereas only one species was previously confirmed to live in the stream. Sewage inflow remains a problem upstream of the extensive rebuilding of the sewer main. The status report, here, details this work which will continue into the spring of 2018.Sing Sing Kill status Report.

ii. Sparta Brook :-

In 2015 a study funded by the Hudson River foundation was carried out. Fish ecology and water quality were studied. Three types of fish were documented as well as eel (which is also a fish) and crayfish (which are of course not a fish). Sewage levels were measured as concentrations of E.coli and enterococcus bacteria and found to be as high as several thousand. A level of 200 is the DEC standard for recreational waters. Future work will seek to identify sources. Further, artistic signage using historic paintings of the Sparta Brook was designed and mounted next to the stream in two locations. For one, a new sitting park across the street from the Jug Tavern was created by the Village of Ossining. The second sign is located at the Sunoco Station on South Highland Avenue.

iii. Kemeys Cove :-

A grant proposal was written in 2016 to reconnect the Sparta Brook with its historic outpouring of Kemeys Cove. This would reintroduce fresh water to the cove and provide extensive fish and wildlife habitat that was lost when they were separated during the construction of the railroad. Negotiations with private property owners along the cove broke down at the last minute and this opportunity for restoration was lost. Hopefully it can be revisited in the future. See grant proposal here.

iv. Sing Sing Kill fish ladder :-

A grant proposal was submitted to the DEC in the spring of 2017 for a fish ladder just below the double arches to allow alewife (herring) to migrate upstream from the Hudson to spawn. It was not funded but the DEC encouraged resubmission at the next funding opportunity. It would be a fascinating to watch from the SSK walkway as the fish climb the ladder. And it would help the restore the Alewife population to the Hudson River and Atlantic Ocean. See summary of proposal here.Fishladder photos and maps.
