Woodside dam
Woodside
Woodside, also known as the Hyde Park Dam, is a private-owned structure located in East Johnson, Vermont along the Gihon River. Built in 1895, this gravity dam stands at a height of 22 feet and has a length of 156 feet, with a primary purpose of generating hydroelectric power. The dam has a storage capacity of 60 acre-feet and a maximum discharge of 927 cubic feet per second, making it a significant contributor to the region's energy production.
Managed by the Federal Energy Regulatory Commission, Woodside has a low hazard potential and is categorized as having a moderate risk level. While it is not state regulated, it falls under federal oversight for operations, inspections, and regulatory compliance. The dam's spillway is uncontrolled, with a width of 34 feet, and it is situated within the New England District of the US Army Corps of Engineers. With its historical significance and role in renewable energy generation, Woodside serves as a notable feature in Vermont's water resource infrastructure.
Overall, Woodside represents a blend of historical significance and modern functionality, playing a crucial role in the region's energy landscape. As a privately-owned hydroelectric facility, it stands as a testament to the state's commitment to sustainable energy practices. With its controlled water storage and discharge capabilities, Woodside contributes to the efficient management of the Gihon River while providing renewable energy to the local community.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Woodside
Where does the data for Woodside come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
