Upper Moore Lake Dam dam
Upper Moore Lake Dam
Upper Moore Lake Dam, located in Miller County, Arkansas, was completed in 1950 and stands at a height of 22 feet with a maximum storage capacity of 198 acre-feet. The dam, primarily used for recreation, is classified as an earth dam and spans a length of 1705 feet along Turkey Creek. Despite its low hazard potential and not being regulated by the state, the dam has a hydraulic height of 17 feet and a normal storage capacity of 88 acre-feet.
Owned privately, Upper Moore Lake Dam has not been subject to state inspection, regulation, or enforcement. While the dam has not been rated for its condition assessment, it is unlikely to pose a significant risk to the surrounding area. With a surface area of 17 acres and a drainage area of 4.2 square miles, the dam has a maximum discharge capacity of 3522 cubic feet per second, serving as a vital resource for water storage and recreation in the region.
As a key feature in the Fort Worth District, Upper Moore Lake Dam plays a crucial role in water management and recreational activities along Turkey Creek. Despite not having an Emergency Action Plan in place, the dam's low hazard potential and its historical significance highlight its importance in the local ecosystem. Water resource and climate enthusiasts will find this dam to be a noteworthy structure that contributes to the sustainable use of water resources in Arkansas.
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 Upper Moore Lake Dam
Where does the data for Upper Moore 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.
