The Onesquethaw-Coeymans Creek


From its source in the Helderberg Mountains to its confluence with the Hudson River, the scenic Onesquethaw-Coeymans creek meanders 19 miles from Helderberg Lake in Berne, through southern Albany County crossing the towns of New Scotland, Bethlehem, and Coeymans.

Helderberg Lake


The Creek is an important natural resource, supporting a high diversity of plants and animals, and feeds the Vly Creek Reservoir, a water supply for the Town of Bethlehem. The watershed also supports many private wells used for drinking water and agriculture.


The surrounding watershed is also rich in cultural resources. Historic buildings and Native American artifacts found in the area are reminders of Albany’s diverse history. The stream corridor also provides many recreational opportunities including trout fishing, hiking, and spelunking.
