Arthur V. Ormond Lock And Dam dam
Arthur V. Ormond Lock And Dam
Arthur V. Ormond Lock and Dam, also known as Pool 9, is a federal water infrastructure located in Morrilton, Arkansas, along the Arkansas River. Completed in 1969, this concrete gravity dam stands at 57 feet tall and stretches 1850 feet in length. Its primary purpose is navigation, but it also serves hydroelectric and recreational purposes. Managed by the US Army Corps of Engineers, the dam has a significant hazard potential and a very high risk assessment rating.
The dam's risk management measures include continuous monitoring, prioritized maintenance activities, and collaboration with local emergency managers to raise awareness and develop emergency response plans. The USACE works to address all types of flood risks associated with the dam, ensuring its structural integrity and the safety of downstream areas. Regular updates to the emergency action plan and maintenance activities are essential to keep the dam functioning properly and ready to respond in case of a dam-related emergency.
Despite its limitations in water storage capacity, Arthur V. Ormond Lock and Dam plays a crucial role in managing water levels and mitigating flood risks. As severe weather events can bring inconsistent or larger amounts of water into the system, the dam's controlled spillway and lock system are essential for maintaining the safety and functionality of the structure. Ongoing efforts by the USACE ensure that the dam is well-equipped to handle potential challenges and protect surrounding communities from the impacts of flooding.

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 Arthur V. Ormond Lock And Dam
Where does the data for Arthur V. Ormond Lock And 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 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.
