Mustang Lake East Dam dam
Mustang Lake East Dam
Mustang Lake East Dam, located in Brazoria, Texas, along the Mustang Bayou, was completed in 1938 for irrigation purposes. This privately owned earth dam stands at a height of 13 feet and has a length of 21,500 feet, providing storage capacity for 8,482 acre-feet of water. Despite its age, the dam is still regulated and inspected by the Texas Commission on Environmental Quality (TCEQ) to ensure its structural integrity and safety.
The dam, designed by Baker and Wachtstetter, features a buttress core type and is situated in a high-risk area, according to the hazard potential assessment. Although the dam has not been rated for its condition, it is important to note that it has not been modified in recent years and lacks a spillway. Furthermore, the last inspection conducted on the dam dates back to April 1985, emphasizing the need for updated assessments and emergency action plans to mitigate potential risks associated with its operation.
Water resource and climate enthusiasts interested in the Mustang Lake East Dam will find its historical significance and structural characteristics intriguing. As a vital component of the local irrigation system, this dam plays a crucial role in water management and agricultural activities in the region. The dam's association with the Mustang Bayou watershed underscores its importance in sustaining water resources for both human and environmental needs, making it a significant landmark for conservation efforts in Texas.

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 Mustang Lake East Dam
Where does the data for Mustang Lake East 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.
