Degray Dam - Reregulation Dam dam
Degray Dam - Reregulation Dam
Degray Dam-Reregulation Dam, also known as Degray Reregulating Lake, is a gravity dam located in Caddo Valley, Arkansas, and is owned and operated by the US Army Corps of Engineers. Completed in 1971, the primary purposes of this hydroelectric dam are for hydroelectric power generation and water supply. With a structural height of 52 feet and a hydraulic height of 37 feet, the dam has a storage capacity of 6,800 acre-feet and a surface area of 90 acres.
The dam has a high hazard potential and a moderate risk rating, with the US Army Corps of Engineers actively managing dam-related flood risks by monitoring its condition, performing maintenance and repairs, and engaging with local emergency managers and the public to raise awareness and preparedness for potential emergencies. While the dam does not eliminate all flood risks, it plays a crucial role in managing water levels and relieving pressure to maintain its structural integrity. Regular inspections, updates to the emergency action plan, and collaboration with local authorities are key components of the risk management measures in place for this important water resource infrastructure.
Overall, Degray Dam-Reregulation Dam serves as a vital structure for hydroelectric power generation and water supply in the region. Its strategic location on the Caddo River, efficient risk management practices, and ongoing maintenance efforts ensure the safety and functionality of the dam for both its intended purposes and the surrounding community. As climate change continues to impact water resources, the importance of well-maintained and managed dams like Degray Dam-Reregulation Dam becomes increasingly apparent in safeguarding against potential flood risks and ensuring sustainable water management practices.
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 Degray Dam - Reregulation Dam
Where does the data for Degray Dam - Reregulation 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.
