Lake Erling Dam dam
Lake Erling Dam
Lake Erling Dam, also known as Percy Cobb Dam, is a private-owned structure located in Lafayette County, Arkansas. Completed in 1956, this rockfill dam serves primarily for recreation and water supply purposes, with a storage capacity of 138,250 acre-feet and a surface area of 2,350 acres. The dam stands at 43 feet high, with a hydraulic height of 30 feet and a structural height of 42 feet, contributing to its significant hazard potential.
Managed by the Arkansas Natural Resources Commission (ANRC), Lake Erling Dam is subject to state regulation, permitting, inspection, and enforcement. Situated on the Bodcau River, the dam not only provides recreational opportunities but also plays a crucial role in water resource management for the surrounding area. With a maximum discharge capacity of 8,000 cubic feet per second, the dam ensures the safety and sustainability of the water supply for the community.
Despite its age, Lake Erling Dam has not been rated for its condition assessment, and details regarding emergency preparedness, risk assessment, and management measures are not readily available. However, the dam's location in a highly regulated state and its compliance with inspection and permitting requirements suggest a commitment to maintaining its structural integrity and safeguarding the water resources it manages for the benefit of 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 Lake Erling Dam
Where does the data for Lake Erling 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.
