Mcmannis Lake Dam dam
Mcmannis Lake Dam
Mcmannis Lake Dam, located in Cuero, Texas, was completed in 1960 by the USDA NRCS and serves multiple purposes, including fire protection, stock, and small fish pond management. The earth dam stands at a height of 15 feet and has a length of 792 feet, providing a storage capacity of 104 acre-feet. With a surface area of 8.6 acres, the dam plays a crucial role in water resource management in the region.
Despite not being regulated by the state, Mcmannis Lake Dam poses a high risk due to its hazard potential being classified as "Not Available." The dam lacks a spillway and has limited emergency preparedness measures in place, raising concerns for potential flooding and safety risks in the event of a breach. Climate enthusiasts and water resource professionals may find interest in monitoring and assessing the condition of the dam to ensure its continued safety and effectiveness in water management.
With its location on TR-Denton Creek, Mcmannis Lake Dam is a key infrastructure for the local community, providing essential water resources for agriculture, fire protection, and recreational purposes. As climate change continues to impact water availability and quality, the maintenance and monitoring of dams like Mcmannis Lake Dam become increasingly important to ensure sustainable water management practices in the face of evolving climate challenges.

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 Mcmannis Lake Dam
Where does the data for Mcmannis 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 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.
