Harriman is a privately owned hydroelectric dam located on the Deerfield River in Readsboro, Vermont. Constructed in 1924, this dam stands at a height of 186 feet and has a length of 1250 feet, providing storage for up to 116,075 acre-feet of water. With a maximum discharge capacity of 35,200 cubic feet per second and a surface area of 1,875 acres, Harriman serves as a critical resource for both hydroelectric power generation and recreational activities.

Managed by the Federal Energy Regulatory Commission, Harriman has a high hazard potential due to its size and location, although the current condition assessment is not available. Despite its age, the dam has undergone no recent modifications and has a moderate risk assessment rating of 3. Emergency action plans have been prepared and updated in compliance with guidelines, ensuring that appropriate measures are in place in the event of a potential risk or emergency situation.

For water resource and climate enthusiasts, Harriman represents a historic feat of engineering that continues to play a vital role in Vermont's energy infrastructure. Its blend of hydroelectric power generation and recreational opportunities highlights the importance of sustainable water management practices in balancing environmental conservation with human needs. As efforts to address climate change intensify, the careful monitoring and maintenance of dams like Harriman will be crucial in safeguarding water resources for future generations.
