Comstock Pond Dam dam
Comstock Pond Dam
Comstock Pond Dam, located in Ivoryton, Connecticut, is a local government-owned structure built in 1874 for regulating the flow of Falls River. This Earth-type dam stands at a height of 7 feet and spans 540 feet, with a storage capacity of 57 acre-feet and a surface area of 5.5 acres. The dam's primary purpose is classified as 'Other', serving various functions related to water resource management in the area.
Despite being categorized as having a low hazard potential, Comstock Pond Dam is subject to state regulation, inspection, and enforcement by the Connecticut Department of Energy and Environmental Protection (DEEP). The dam's spillway, with a width of 25 feet, is of the uncontrolled type, capable of accommodating a maximum discharge of 186 cubic feet per second. With a moderate risk assessment rating of 3, the dam remains in a 'Not Rated' condition, suggesting a need for further evaluation and maintenance to ensure its continued safety and functionality.
For water resource and climate enthusiasts, Comstock Pond Dam serves as a vital infrastructure component in managing water flow and storage in the region. With its historical significance dating back to the 19th century, the dam represents a tangible connection to the area's past while also playing a crucial role in supporting present-day water management efforts. As discussions around climate change and water resource sustainability continue to evolve, the maintenance and upkeep of structures like Comstock Pond Dam will be essential in ensuring the resilience of local ecosystems and communities in the face of changing environmental conditions.

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 Comstock Pond Dam
Where does the data for Comstock Pond Dam 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.
