Lake Ninevah dam
Lake Ninevah
Lake Ninevah, also known as Patch Lake, is a private water resource located in Mount Holly, Vermont. This picturesque lake is nestled in the Rutland County area, with its primary purpose being recreation. The dam constructed in 1930 is primarily an earth dam with stone core types, standing at a height of 13 feet and a length of 176 feet. With a storage capacity of 1500 acre-feet and a surface area of 237 acres, Lake Ninevah offers a tranquil setting for outdoor enthusiasts to enjoy various water activities.
Managed by the Vermont Department of Environmental Conservation (DEC), Lake Ninevah is regulated, inspected, and enforced by the state agency to ensure its safety and compliance with environmental standards. The dam, spanning Patch Brook, plays a significant role in water management and flood control in the region, with a drainage area of 1.2 square miles. Despite being classified as having a significant hazard potential, the dam's condition was assessed as fair as of July 2018, indicating ongoing efforts to maintain its integrity and safety for the surrounding community.
With its rich history dating back to the early 20th century, Lake Ninevah continues to be a beloved destination for water and climate enthusiasts seeking a peaceful retreat in the heart of Vermont. As one of the state's regulated water resources, the lake offers a blend of natural beauty and recreational opportunities, inviting visitors to immerse themselves in its serene surroundings while appreciating the careful management and maintenance efforts that preserve this valuable ecosystem for future generations.
Dam data reference
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 Lake Ninevah
Where does the data for Lake Ninevah 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 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.
