About this dam

Adams Lake Dam

Adams Lake Dam, located in Greenland, Arkansas, was completed in 1955 and serves primarily for recreational purposes. This earth dam stands at a height of 23 feet and has a storage capacity of 260 acre-feet, with a normal storage level of 190 acre-feet. The dam's reservoir, Adams Lake, is fed by Ward Slough-Tr and covers a surface area of approximately 300 feet.

Despite its recreational function, Adams Lake Dam is classified as having a significant hazard potential and is currently not rated in terms of condition assessment. The dam, owned privately, is not regulated or inspected by state agencies, indicating the need for increased monitoring and maintenance measures. Additionally, the dam does not have an Emergency Action Plan in place, raising concerns about preparedness in case of emergencies or natural disasters.

Overall, Adams Lake Dam poses a notable risk due to its significant hazard potential and lack of regulatory oversight. As a key feature for recreation in the area, it is crucial for the dam's owners to prioritize safety measures and regular inspections to ensure the integrity and stability of the structure. With its picturesque location and importance for water resource management, Adams Lake Dam warrants increased attention and proactive risk management strategies to safeguard the community and environment it serves.

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.

FAQ

About Adams Lake Dam

Where does the data for Adams 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 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.
