About this dam

Smith Farm

Smith Farm in Aroostook, Maine, is home to a significant earth dam constructed in 1966 by the USDA NRCS, with the primary purpose of flood risk reduction along Smith Brook. The dam stands at a structural height of 35 feet with a hydraulic height of 30 feet, providing a storage capacity of 180 acre-feet and covering a surface area of 10 acres. With a spillway width of 60 feet, the dam plays a crucial role in mitigating flood risks and ensuring irrigation for the surrounding agricultural lands.

Maintained by the Natural Resources Conservation Service, Smith Farm dam is regulated by MEMA and undergoes inspections every 6 years to assess its fair condition and significant hazard potential. Despite its age, the dam continues to serve its purpose effectively, reflecting the sound engineering and design principles implemented by the USDA NRCS. The dam's location within the New England District further underscores its importance in water resource management and climate resilience efforts, highlighting the collaboration between federal and state agencies to safeguard the community from potential flood events.

As a private-owned structure, Smith Farm dam remains a vital asset in the region's water infrastructure, contributing to flood risk reduction, irrigation, and other purposes. With its historical significance and ongoing regulatory oversight, the dam at Smith Farm stands as a testament to the enduring commitment towards sustainable water resource management and climate adaptation in the face of evolving environmental challenges.

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 Smith Farm

Where does the data for Smith Farm 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.
