About this dam

Mcallister Pond

Mcallister Pond, located in Stowe, Vermont, is a private water resource primarily used for recreation. The pond is associated with Barrows Brook-TR and has a storage capacity of 10 acre-feet and a surface area of 1.5 acres, serving as a significant water source with a fair condition assessment. While the dam type is listed as earth with a buttress core, specific structural details such as height and length are unknown.

Despite being privately owned and not regulated by the state, Mcallister Pond poses a significant hazard potential and has been assessed as fair in condition as of July 2004. Emergency action plans and risk management measures are not currently in place, suggesting a need for updated safety protocols and guidelines to mitigate potential risks associated with the dam. With its scenic location in Lamoille County, Vermont, Mcallister Pond offers opportunities for outdoor enthusiasts to enjoy recreational activities such as fishing and boating in a natural setting.

Overall, Mcallister Pond serves as a valuable water resource in the region, providing both recreational opportunities and potential risks that warrant attention from stakeholders and authorities. As a privately owned dam with a significant hazard potential, continued monitoring and maintenance efforts are essential to ensure the safety and sustainability of this water source for future generations. Climate enthusiasts and water resource professionals alike can appreciate the importance of balancing recreational use with safety measures to protect the integrity of Mcallister Pond and its surrounding ecosystem.

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.

FAQ

About Mcallister Pond

Where does the data for Mcallister Pond 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.
