Curtis Dam

Rehabilitation of Curtis Dam

Curtis Dam is located on the upper Hudson River inside the Adirondack park (New York) and is owned by TransCanada Power. In 2001, Regional Power was engaged by TransCanada to manage the rehabilitating project for the Curtis Dam. The rehabilitation project was the replace the wooden flashboard system with an inflatable rubber crest gate within two years to meet their operating agreement. The dam’s existing wooden flashboard system failed every year during high flow season and winter ice jams resulting in loss of power generation and revenue.

Regional Power identified innovative design, fabrication, and installation approaches which reduced costs and shortened the construction schedule:

  • Coffer dam concept eliminated the need for two federal agency reviews and permit processes
  • Dam alteration concept eliminated the need for one lengthy state agency review and permit
  • Parallel field preparation / shop fabrication approach enabled tight control of final crest shape

The rehabilitation of Curtis Dam was successful. Its benefits included the enhancement of seasonal fish production and higher power generation.
