Lake Hortonia Dam
Lake Hortonia
Lake Hortonia, located in Hubbardton, Vermont, is a picturesque water resource with a primary purpose of recreation. The dam at Lake Hortonia is a concrete structure with a height of 16 feet and a length of 150 feet, completed in 1955. With a storage capacity of 4500 acre-feet and a surface area of 449 acres, the lake provides ample opportunities for outdoor activities such as boating, fishing, and swimming.
Managed by the Vermont Department of Environmental Conservation, Lake Hortonia is regulated, permitted, inspected, and enforced by the state agency to ensure its safety and compliance with environmental standards. The dam is classified as having a significant hazard potential, but is currently assessed to be in fair condition as of the last inspection in August 2016. While there are no associated structures or spillways, the dam serves as a key element in maintaining the water levels of the Hubbardton River-TR tributary.
Water and climate enthusiasts visiting Lake Hortonia can appreciate its serene beauty and recreational offerings, while also recognizing the importance of responsible management and maintenance of the dam to ensure the safety of the surrounding community and environment. As one of the many water resources in Vermont, Lake Hortonia serves as a reminder of the delicate balance between human enjoyment of natural resources and the need for sustainable conservation practices in the face of climate change.

About Lake Hortonia
Where does the data for Lake Hortonia 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 Significant 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 below 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.

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.
