Schoharie Creek in New York, USA flows north 93 miles (150 km) from the foot of Indian Head Mountain in the Catskill Mountains through the Schoharie Valley to the Mohawk River. It is twice impounded north of Prattsville to create New York City's Schoharie Reservoir and the Blenheim-Gilboa Power Project.
During the American Revolutionary War, Iroquois Indian attacks against the cluster of farms in the valley of the Cobleskill Creek tributary was the site of the Cobleskill Massacre (May 1778), virtually depopulating settlements in the southern Mohawk valley. News of this and two other mixed Tory-Indian guerrilla attacks lead to an appropriation of funds for the Sullivan Expedition dispatched by General Washington in 1779 to break the threat of Indian raids.
Two notable bridge collapses have occurred on the Schoharie Creek. In 1987, two spans of the New York State Thruway collapsed. On August 28, 2011, the covered Old Blenheim Bridge collapsed due to flooding from Hurricane Irene.
Watershed and tributary streams
Schoharie Creek is part of the drainage system of the Hudson River watershed and a direct tributary of the Mohawk River. It has the sister-tributaries: Alplaus Kill, Plotter Kill, North Chuctanunda Creek, South Chuctanunda Creek. These regional streams are tributaries of Schoharie Creek (and its tributaries):
In the 18th century, areas of the south (or right bank) side of Mohawk Valley were sparsely settled in the face of the periodically warlike and always militant Iroquois peoples, who, while diminished by European diseases during colonial times still retained ample war powers after the French and Indian War ended in 1763. Reorganized by then as the Six Nations the tribes had conducted internecine war with other powerful eastern tribes until the 1770s, weakening or eliminating the power of the Delaware, the Susquehanna, and Shawnee tribes— affecting Amerindian populations and power both East and West of the Alleghenies as far south as northern Kentucky in the west, and southern Maryland in the east. By the end of the French and Indian War, they were the one remaining group of eastern native peoples that retained sufficient military power to give even the British authorities pause. Consequently, those authorities cultivated political arrangements with the Iroquois and as a prelude to the revolution, the British Crown acted to block trans-Appalachian settlements before the opening of the American Revolution, one of the lesser known grievances of many held by the settlers.
During the Revolution, farms in the valley acted as a breadbasket providing important food supplies to the Colonial forces. The lower Mohawk valley was a scene of uneasy native Amerindian–Colonial Settler contention throughout most of the 18th century until after the American Revolutionary War's Sullivan Expedition pacified the region by permanently weakening the Six Nations of the Iroquois. That campaign was a direct result of two atrocities in the region: The May 1778 Battle of Cobleskill (or Cobleskill Creek Massacre) signaled a new guerrilla war offensive by mixed troops of Loyalists and members of the four Iroquois tribes allied to the British in 1778. The incursions resulted in three major raids with major loss of life ranging from Southern New York to Wilkes-Barre, Pennsylvania.
Old Blenheim Bridge
The Old Blenheim Bridge, one of the longest and oldest single-span covered bridges in the world, formerly spanned the creek. The bridge was destroyed on August 28, 2011 by flooding resulting from Hurricane Irene.
New York State Thruway
- Bridge collapses
On the morning of April 5, 1987, after 30 years of service, two spans of the New York State Thruway bridge over the Schoharie Creek near Fort Hunter collapsed. Five vehicles fell into the flooded river, ten of the occupants died.
