Twin Lakes Dam B dam
Twin Lakes Dam B
Twin Lakes Dam B, located in Pulaski, Arkansas, is a privately owned earth dam primarily used for recreation purposes. Completed in 1964, this dam stands at a height of 15 feet and has a hydraulic height of 12 feet, with a total length of 537 feet. It has a storage capacity of 60 acre-feet, with a normal storage level of 34 acre-feet, serving as a popular spot for outdoor enthusiasts in the area.
Situated on Rock Creek, this dam poses a high hazard potential and has not been rated for its current condition as of the last inspection in 1992. Despite its age, Twin Lakes Dam B remains a key recreational attraction in the region, drawing visitors to its serene surroundings and water activities. The dam's emergency action plan status, risk assessment, and management measures are not available, highlighting the need for ongoing monitoring and maintenance to ensure safety and continued enjoyment for all who visit.
Although not under state regulation or jurisdiction, Twin Lakes Dam B is a vital part of the local landscape and contributes to the natural beauty of Little Rock. As water resource and climate enthusiasts, it is important to appreciate and support the upkeep of such structures to preserve the ecological balance and recreational opportunities they provide. With its rich history and potential risks, Twin Lakes Dam B serves as a reminder of the importance of responsible stewardship of our water resources for future generations to enjoy.

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
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Twin Lakes Dam B
Where does the data for Twin Lakes Dam B 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.
