Gordon Cobb Lake Dam dam
Gordon Cobb Lake Dam
Gordon Cobb Lake Dam in Hockley, Texas, is a vital structure for water supply, serving as a primary source of water for the region since its completion in 1934. This Earth-type dam stands at a height of 24 feet and has a storage capacity of 178 acre-feet, with a normal storage level of 96 acre-feet. The dam overlooks the Yellow House Draw and is owned privately, with state permitting and inspection in place.
Despite its historical significance and importance for water resource management, Gordon Cobb Lake Dam faces some challenges in terms of risk assessment. It has been rated as having a high risk potential (2) due to its hazard potential not being available, and its condition assessment remains unrated. However, the dam has not been assigned an Emergency Action Plan (EAP) or undergone a risk management assessment yet, highlighting the need for proactive measures to ensure its safety and resilience in the face of potential hazards.
As a water resource and climate enthusiast, Gordon Cobb Lake Dam presents an intriguing case study for understanding the complexities of managing aging infrastructure and ensuring the safety and efficiency of water supply systems. Its location in Hockley, Texas, within the Fort Worth District, underscores the importance of ongoing monitoring and maintenance to address the identified risks and improve the overall resilience of the dam in the face of changing environmental conditions and potential emergencies.

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 Gordon Cobb Lake Dam
Where does the data for Gordon Cobb 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.
