Mulberry Reservoir Dam dam
Mulberry Reservoir Dam
Mulberry Reservoir Dam, located in Naugatuck, Connecticut, is a crucial public utility structure designed for water supply purposes. Completed in 1897, this Earth-type dam stands at a height of 66 feet and spans 580 feet in length, with a storage capacity of 205 acre-feet. Situated on the Naugatuck River Tributary, the dam serves as a vital resource for the surrounding area, with a normal storage capacity of 145 acre-feet and a maximum discharge of 1600 cubic feet per second.
State regulated by the Connecticut Department of Energy and Environmental Protection (DEEP), Mulberry Reservoir Dam has a high hazard potential but is currently deemed to be in satisfactory condition following the most recent assessment in November 2020. The dam's emergency action plan (EAP) was last revised in June 2018, and it meets regulatory guidelines. With a history of regular inspections and a designated inspection frequency of every 2 years, Mulberry Reservoir Dam remains a critical piece of infrastructure for water resource management in the region.
Managed by a public utility owner, Mulberry Reservoir Dam plays a vital role in water supply infrastructure in New Haven County. With its strategic location and efficient design, the dam ensures a reliable water source for the local community while adhering to state regulatory standards for inspection, enforcement, and permitting. As climate change continues to impact water resources, Mulberry Reservoir Dam stands as a testament to the importance of resilient and well-maintained infrastructure in the face of evolving environmental challenges.
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 Mulberry Reservoir Dam
Where does the data for Mulberry Reservoir 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 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.
