North Pond Reservoir Dikes dam
North Pond Reservoir Dikes
The North Pond Reservoir Dikes in Norfolk, Connecticut, are vital structures owned by a public utility for water supply purposes. These dikes, constructed with stone core types, have a dam height of 17 feet and a length of 840 feet, providing a storage capacity of 2300 acre-feet. Despite their high hazard potential, the dikes are in satisfactory condition and have been inspected regularly, with the last assessment conducted in June 2019.
Located in Litchfield County, the North Pond Reservoir Dikes are regulated by the Connecticut Department of Energy and Environmental Protection (DEEP) and have state jurisdiction for permitting, inspection, and enforcement. The surrounding area benefits from the reservoir's water supply function, ensuring a reliable source of water for various uses. The dikes have no spillway and are not associated with any federal agencies, making them solely under state oversight, with a high-risk classification of 2.
In the event of an emergency, the dikes have a satisfactory emergency action plan (EAP) in place, although the last revision was in February 2017. With a high risk assessment, it is crucial for the responsible authorities to ensure that the necessary risk management measures are in place to protect the surrounding community and maintain the structural integrity of the North Pond Reservoir Dikes. For water resource and climate enthusiasts, these dikes represent a crucial infrastructure piece in Connecticut's water supply system, highlighting the importance of proper maintenance and regulation in safeguarding our water resources.
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 North Pond Reservoir Dikes
Where does the data for North Pond Reservoir Dikes 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 High 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.
