NEW YORK (AP)– New York City has finished a $138 million reconstruction of an 87-year-old dam in its upstate watershed.

Work on the Gilboa Dam being unveiled Friday includes replacement of the old bluestone face with poured concrete and an inspection gallery running along the dam’s length. Work started on Gilboa after inspections revealed the dam could fail under extreme stress, raising alarms among the roughly 8,000 people living in the downstream towns and villages east of Albany.

The Gilboa Dam, completed in 1927, holds back the Schoharie Reservoir. It is the northernmost reservoir in the city’s sprawling upstate watershed.

Water from the 19.2 billion-gallon reservoir flows more than 100 miles south to city faucets, largely through tunnels.
