A Dam Too Far: Million Dollar Dam & McGregor Powerhouse

Not currently being offered
2020

William H. Miner is perhaps best known as the wealthy railroad industrialist who returned to his modest Chazy farm to construct a 15,000-acre model farm in the early 20th century, but he also undertook numerous hydroelectric projects throughout the North Country. Located eight miles from Miner Institute is a 6,800-acre sandstone pavement barren known as the Altona Flat Rock. Within this rare ecosystem are a series of reservoirs and small streams that were once the site of one of Miner’s hydroelectric projects – a 2,300-foot long “Million Dollar” dam. Constructed in 22 months by 500 workers, this engineering marvel held approximately 1 billion gallons of water and operated for seven years. The tour will include a walk to the crest of the dam to view its expanse, the cement road, and the “scarpit” reservoir.

After we will visit the Altona Flat Rock Dam and will see the second of Miner’s hydroelectric marvels in Altona – the intact McGregor Powerhouse. To power this, Miner constructed a 1,500-foot-long dam on McGregor Pond in 1922 to create Miner Lake. The imposing powerhouse is like nothing else surrounding it, and remains standing as an elaborate, concrete-stucco Spanish Revival-style building, which once featured apartments upstairs for workers and their families. This tour will give you an up-close, behind-the-scenes look at both of these historic hydroelectric sites.

This tour will be led by William H. Miner Agricultural Research Institute Librarian Amy Bedard and additional staff. The tour begins at 10 AM and ends around 3 PM.

The fee is $50 for members and $60 for non-members.

Please note that this tour includes just under two miles of walking over some uneven terrain.

Please note that there are a limited number of seats in two Miner Institute vehicles, which will be filled by the lottery, then subsequent requests from AARCH Staff. If you have a vehicle that drives over rough terrain, you may take your own vehicle, and possibly allow for carpooling as well.
