Schoharie Creek and West Canada Creek are the two principle tributaries of the Mohawk River.  Schoharie Creek flows northward from of northern flanks of the Catskill mountains, while West Canada Creek flows south from the Adirondack mountains.  It is not uncommon for one to be in flood stage, while the other is not. Both have had devastating historic floods, with the most notable being the 1996 mid-winter flood on the Schoharie, and the 1910 mid-winter flood on the West Canada.

Schoharie Creek flows through the towns of Middleburg and Schoharie, so flooding is of interest to a number of people directly impacted by high water. The Schoharie Creek has two dams that impound water.  The upper headwaters are dammed by the 120 foot high Gilboa Dam, which forms the Schoharie Reservoir, a NY City water supply that was put into service in 1926.  In 2005 the dam had clear deficiencies, which initiated a long and costly process of renovation.  An advocacy group called Dam Concerned Citizens has been active in a public information campaign and community awareness.  

Downstream from the Gilboa dam is the Blenheim-Gilboa Pumped Storage Power Project which is part of the NY power Authority, and it will be able to generate 1,160 megawatts when the ongoing modernization project is complete.

We are just now starting to investigate scientific and policy issues of Schoharie Creek.
