About this dam

Milton

Milton, also known as Great Falls Dam, is a captivating hydroelectric structure located in West Milton, Vermont. Built in 1929, this concrete gravity dam stands at 25 feet tall and spans 144 feet in length, harnessing the power of the Lamoille River to generate clean energy. With a storage capacity of 93 acre-feet and a maximum discharge of 83,000 cubic feet per second, Milton plays a crucial role in providing renewable energy to the region.

Managed by a public utility, Milton falls under the jurisdiction of the Federal Energy Regulatory Commission (FERC) and is not subject to state regulation. Despite its low hazard potential, Milton poses a very high risk due to its age and the lack of recent condition assessments. The dam's controlled spillway and outlet gates contribute to its safe operation and the surrounding area's protection from potential flooding events. As an essential part of Vermont's water infrastructure, Milton serves as a reminder of the importance of sustainable energy production and resource management in the face of a changing climate.

Overall, Milton stands as a testament to the ingenuity of early hydroelectric engineering and the ongoing need for responsible maintenance and regulation of water resources. Its historical significance and continued operation in the modern era highlight the intersection of environmental conservation, renewable energy production, and climate resilience. As water resource and climate enthusiasts, we must continue to monitor and support structures like Milton to ensure their long-term viability and contribution to a sustainable future.

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 Milton

Where does the data for Milton 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.

Premium feature

Favorites and alerts are part of Snoflo Premium. Save reservoirs, set storage thresholds, and get push notifications when conditions cross.
