Dwiggins Lake Dam dam
Dwiggins Lake Dam
Dwiggins Lake Dam, located in Clark County, Arkansas, was completed in 1948 with a primary purpose of recreation, as well as water supply. The dam, designed by USDA NRCS, is an earth dam with a structural height of 23 feet and a hydraulic height of 18 feet. It impounds Mathews Creek-TR and has a storage capacity of 70 acre-feet, with a normal storage level of 43 acre-feet.
Despite its low hazard potential, Dwiggins Lake Dam has not been rated for its condition assessment. It is privately owned and not regulated by the state, with no inspections or enforcement actions reported. The dam does not have a spillway and has not been modified in recent years. The lack of updated emergency action plans and risk assessments raise concerns about the dam's readiness for potential emergencies.
For water resource and climate enthusiasts, Dwiggins Lake Dam presents an interesting case study in the management of private dams for recreational and water supply purposes. The dam's location in Antoine, Arkansas, and its association with Mathews Creek-TR highlight the importance of sustainable water management practices in the region. As stakeholders monitor the condition and safety of the dam, there is an opportunity to implement risk management measures and update emergency preparedness plans to ensure the long-term resilience of this vital water infrastructure.
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.
Plan around the weather

About Dwiggins Lake Dam
Where does the data for Dwiggins Lake 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 Low 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.
