Lake New Moon Dam dam
Lake New Moon Dam
Lake New Moon Dam, located in Saline, Arkansas, was completed in 1938 and is primarily used for water supply purposes. The dam, with a hydraulic height of 13 feet and a structural height of 15 feet, impounds Caney Creek-TR and has a maximum storage capacity of 54 acre-feet. With a low hazard potential and a moderate risk assessment rating, the dam is not currently regulated by the state and has not been subject to recent inspections.
Owned by a private entity, Lake New Moon Dam was designed by the USDA NRCS and is operated by the Natural Resources Conservation Service. The dam features an uncontrolled spillway type and spans 805 feet in length. Despite its age, the dam's condition assessment is listed as "Not Rated," indicating that its structural integrity has not been recently evaluated. With no emergency action plan in place and limited risk management measures identified, the dam presents a moderate risk in the event of a breach or failure.
Although not currently under state jurisdiction or regulation, Lake New Moon Dam serves as a vital water resource for the area, storing up to 54 acre-feet of water for various purposes. With its historical significance dating back to the late 1930s, the dam stands as a testament to early water supply infrastructure in Arkansas. As climate change continues to impact water resources, the maintenance and monitoring of dams like Lake New Moon Dam become increasingly important to ensure the safety and reliability of water supplies in the region.
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 Lake New Moon Dam
Where does the data for Lake New Moon 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.
