East Brass Mill Dam dam
East Brass Mill Dam
East Brass Mill Dam, also known as Scovill Aka Century Brass Aka City Mills, is a privately owned structure located in Waterbury, Connecticut. Completed in 1916, this concrete dam stands at 25 feet high and stretches 420 feet in length, with a primary purpose of water supply. Situated on the Mad River, it has a normal storage capacity of 120 acre-feet and a maximum discharge rate of 4000 cubic feet per second.
Owned by a private entity, East Brass Mill Dam is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP). While its hazard potential is currently classified as undetermined and its condition not rated, the dam's safety and maintenance are regularly inspected and enforced by state authorities. Despite being non-federally owned, this dam plays a crucial role in water resource management within the region, serving as a key infrastructure for water supply in the area.
For water resource and climate enthusiasts, East Brass Mill Dam presents an intriguing case study of a historic concrete structure that continues to provide essential water supply functions in the modern era. With its location in the New Haven County and proximity to the city of Waterbury, this dam serves as a vital component of the local water infrastructure, ensuring reliable water storage and distribution for the surrounding community. As efforts to monitor and assess the dam's condition and safety continue, it remains an integral part of the region's water management efforts and a fascinating example of early 20th-century engineering in action.
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 East Brass Mill Dam
Where does the data for East Brass Mill 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 Undetermined 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.
