Mangum Lake No 1 Dam dam
Mangum Lake No 1 Dam
Mangum Lake No 1 Dam, located in Maverick County, Texas, stands as a testament to water resource management in the region. Built in 1963, this private-owned Earth dam stretches 885 feet in length and reaches a height of 17 feet, with a storage capacity of 143 acre-feet. Situated on the TR-ELM CREEK, this dam serves a primary purpose of "Other," indicating its critical role in supporting the local ecosystem and water supply.
Despite its age, the dam has been inspected and maintained over the years, with the last inspection conducted in March 1990. While the hazard potential is marked as "Not Available," the risk assessment is classified as high (2), emphasizing the importance of ongoing monitoring and management. With no spillway and limited structural information available, it is evident that Mangum Lake No 1 Dam requires continued attention and investment to ensure its safety and effectiveness in the face of changing climate conditions.
As climate enthusiasts and water resource advocates continue to push for sustainable solutions, the story of Mangum Lake No 1 Dam serves as a reminder of the intricate balance between human infrastructure and natural ecosystems. With its location in a region prone to water scarcity and drought, the dam represents a vital lifeline for the community and surrounding environment. As discussions around climate resilience and water management evolve, the future of Mangum Lake No 1 Dam will be closely watched to ensure its continued role in supporting the local ecosystem and water security.

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 Mangum Lake No 1 Dam
Where does the data for Mangum Lake No 1 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 Not Available 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.
