Lake Pennington Dam dam
Lake Pennington Dam
Lake Pennington Dam, located in Houston, Texas, stands as a testament to the vital role of water resources in supporting agricultural irrigation. Completed in 1957, this earth dam, with a height of 18 feet and a length of 470 feet, serves as a critical water storage facility with a capacity of 300 acre-feet and a normal storage of 140 acre-feet. Despite its age, the dam's condition remains unrated, suggesting a need for further assessment to ensure its continued functionality.
With the absence of a spillway and limited information on its hazard potential, Lake Pennington Dam presents a potential risk, marked as high. The dam's primary purpose of irrigation underscores its importance in supporting local agriculture, while its association with the Pennington Branch emphasizes its significance in sustaining the region's water supply. As a privately owned structure, the dam's maintenance and regulatory oversight fall under state jurisdiction, highlighting the need for proactive management to address any potential risks and ensure the safety of the surrounding community and environment.
While the dam's last inspection dates back to 1983, the lack of information on emergency preparedness and risk management measures raises concerns about the dam's resilience in the face of potential hazards. As water resource and climate enthusiasts, it is imperative to advocate for the regular assessment and maintenance of structures like Lake Pennington Dam to safeguard both water security and environmental sustainability for future generations.

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 Lake Pennington Dam
Where does the data for Lake Pennington 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.
