Mccullough Lake Levee dam
Mccullough Lake Levee
Mccullough Lake Levee, located in Brazoria, Texas, was completed in 1963 and serves as a vital recreational resource in the area. The earth dam, with a height of 9 feet and a length of 8690 feet, provides a storage capacity of 928 acre-feet and a normal storage of 405 acre-feet. Despite being primarily designed for recreation, the levee is also state-regulated and regularly inspected by the Texas Commission on Environmental Quality (TCEQ) to ensure its safety and effectiveness.
The levee, situated off CH-Austin Bayou, is owned privately and falls under the jurisdiction of the state of Texas. With no spillway and a hazard potential deemed "Not Available," the structure poses a moderate risk, as reflected in its risk assessment ranking of "High (2)." While the condition assessment remains "Not Rated," the levee's emergency action plan (EAP) was last revised in 2009, indicating a proactive approach to emergency preparedness. Despite some gaps in data, Mccullough Lake Levee stands as a significant feature in the local landscape, providing both recreational enjoyment and critical water resource management.
Managed by the Fort Worth District of the US Army Corps of Engineers, Mccullough Lake Levee plays a crucial role in water resource management and flood control efforts in the region. The levee's strategic location and design contribute to the overall resilience of the area, mitigating potential risks and ensuring the safety of nearby communities. With ongoing state inspections and regulatory oversight, Mccullough Lake Levee remains a key asset in the region's water infrastructure, highlighting the importance of sustainable water resource management in the face of changing climate patterns and environmental 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 Mccullough Lake Levee
Where does the data for Mccullough Lake Levee 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.
