About this dam

Munoz Lake Dam

Munoz Lake Dam, located in Starr County, Texas, stands as a testament to the importance of water resource management in the region. Built in 1964, this private earth dam serves multiple purposes including fire protection, livestock watering, and as a small fish pond. With a height of 20 feet and a length of 850 feet, the dam has a storage capacity of 127 acre-feet and covers a surface area of 8.7 acres.

Despite its age, Munoz Lake Dam remains a critical infrastructure for the local community. The dam's spillway, with a width of 100 feet, is uncontrolled, reflecting its primary focus on smaller-scale water management. While the dam is not state-regulated, it undergoes regular inspections and maintenance to ensure its structural integrity and functionality. The risk assessment for the dam is moderate, highlighting the need for continued monitoring and management to mitigate any potential hazards.

Managed by private owners, Munoz Lake Dam serves as a vital resource for water supply and conservation in the area. Its strategic location along the TR-Arroyo Grande stream underscores its importance in maintaining water levels for irrigation, livestock, and emergency fire protection. As water resource and climate enthusiasts, it is crucial to recognize the role of dams like Munoz Lake in sustaining ecosystems and supporting local communities in their water management efforts.

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.

FAQ

About Munoz Lake Dam

Where does the data for Munoz 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.
