Morrisville dam
Morrisville
Morrisville, a hydroelectric dam located in Hyde Park, Vermont, harnesses the power of the Lamoille River to generate clean energy. Completed in 1924, this Gravity-type dam stands at 29 feet high and stretches 250 feet in length, with a storage capacity of 150 acre-feet. With a low hazard potential, Morrisville has a controlled spillway and a maximum discharge of 140,000 cubic feet per second, ensuring safety and efficiency in its operations.
Managed by the Federal Energy Regulatory Commission, Morrisville plays a crucial role in the region's energy infrastructure. Its strategic location within the New England District enables it to efficiently serve the community while minimizing environmental impact. Despite its age, Morrisville continues to operate effectively, meeting the high-risk assessment standards set by regulatory agencies.
Water resource and climate enthusiasts will appreciate Morrisville's contribution to sustainable energy production and its adherence to safety and regulatory guidelines. As a key player in Vermont's hydroelectric landscape, Morrisville exemplifies the balance between harnessing natural resources for power generation and protecting the environment for future generations. Its continued operation underscores the importance of maintaining and modernizing existing infrastructure to meet growing energy demands in a responsible manner.

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 Morrisville
Where does the data for Morrisville 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.
