Dieterich Dam #2 dam
Dieterich Dam #2
Dieterich Dam #2 is a historic masonry dam located in Millbrook, New York, along the Mill Brook river. Built in 1910, the dam serves multiple purposes including fire protection, stock, and small fish pond. With a height of 14 feet and a length of 525 feet, the dam has a maximum storage capacity of 14 acre-feet and a normal storage of 12 acre-feet. Despite its age, the dam has a significant hazard potential and a poor condition assessment, indicating the need for ongoing maintenance and potential upgrades to ensure its safety and integrity.
The dam features an uncontrolled spillway with a width of 50 feet and has a maximum discharge capacity of 1150 cubic feet per second. It is regulated by the New York State Department of Environmental Conservation and undergoes regular inspections, with the last one conducted in April 2019. The dam's risk assessment is rated as moderate, highlighting the importance of implementing proper risk management measures to mitigate potential hazards and protect surrounding areas from flooding or other safety concerns. Overall, Dieterich Dam #2 is a vital structure for local water resource management and climate resilience efforts in Dutchess County, New York.
As a privately owned dam, Dieterich Dam #2 plays a crucial role in providing essential water services for the community while also posing a significant risk due to its poor condition and aging infrastructure. It is important for the dam's owners to work closely with regulatory agencies and implement necessary maintenance and upgrades to ensure its long-term stability and safety. With its rich history and functional importance, the dam serves as a reminder of the ongoing challenges and opportunities in managing water resources and adapting to changing climate conditions in the region.

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 Dieterich Dam #2
Where does the data for Dieterich Dam #2 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 Significant 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.
