A.B. Brown Power Plant dam
A.B. Brown Power Plant
The A.B. Brown Power Plant in Posey, Indiana, stands as a vital piece of infrastructure in the region, with a dam completed in 1975 along an unnamed tributary of the Ohio River. Managed by a public utility, the plant is state-regulated and undergoes regular inspections to ensure compliance with environmental and safety standards. The dam, primarily designed for purposes beyond hydroelectric power generation, stands at a height of 68 feet and has a storage capacity of 3,400 acre-feet.
With a spillway type classified as "Uncontrolled" and a hazard potential rated as "High," the A.B. Brown Power Plant presents both challenges and opportunities in water resource management and climate resilience. The dam's fair condition assessment and moderate risk assessment underscore the need for ongoing monitoring and risk management measures. In the event of emergencies, the plant's emergency action plan and contact information must be up to date to ensure swift response and mitigation of any potential threats to the surrounding community and environment.
As climate change continues to impact water resources and infrastructure, the A.B. Brown Power Plant serves as a critical site for comprehensive risk assessment and management. With its strategic location and significant storage capacity, the plant plays a key role in water supply and flood control efforts in the region. Continued investment in monitoring and maintenance will be essential to ensure the long-term sustainability and safety of this important facility 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 A.B. Brown Power Plant
Where does the data for A.B. Brown Power Plant 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.
