Saw Kill Watershed Data

The Saw Kill is 14.3 miles
long and is contained within a 26.2-square-mile watershed that includes land in the towns of Red Hook, Milan, and Rhinebeck. It is a subwatershed of the Hudson Direct Drainage system, which includes all direct drainages in western Dutchess County. 

The Bard Water Lab analyzes samples from the Saw Kill for sewage-indicating bacteria, turbidity, chlorophyll a, colored dissolved organic material (CDOM), phycocyanin, and optical brighteners (OB). We also record temperature and conductivity data for the Saw Kill that our volunteers collect while sampling. The lab maintains a data archive for the Saw Kill Watershed Community that houses historic water-quality data, maps of subbasins, riparian buffers, wetlands, impervious surfaces, and dams in the Saw Kill watershed, and a collection of relevant scientific literature.

Saw Kill Watershed

The Saw Kill includes portions of three towns—Red Hook, Milan, and Rhinebeck—the village of Red Hook, and the Bard College campus within its 26-square-mile watershed. It is a “direct drainage” tributary to the Hudson River, a source of drinking water, and also a place where treated water is released. The stream and its watershed contain a variety of ecological communities—aquatic, wetland, woodland, field—that support diverse populations of plants, fish, and wildlife. Interest in the Saw Kill’s water quality began with sampling in the late 1970s and with several ecological studies originating at Bard College. The sampling program was revived in 2016 with the development of the Bard Water Lab.
