Tmpa Gibbons Creek Mine Dam 5a dam
Tmpa Gibbons Creek Mine Dam 5a
Tmpa Gibbons Creek Mine Dam 5a in Grimes, Texas, is a vital water resource structure regulated by the Texas Commission on Environmental Quality (TCEQ). Completed in 1982, this earth dam stands at a height of 26 feet and spans a length of 4200 feet, serving as a key component in managing water flow along Dry Creek. With a maximum storage capacity of 969 acre-feet and a normal storage level of 204 acre-feet, the dam plays a crucial role in flood control and water supply management in the region.
Despite being uncontrolled, the spillway of Tmpa Gibbons Creek Mine Dam 5a is designed with a width of 300 feet to handle a maximum discharge of 24,308 cubic feet per second. The dam's hazard potential is deemed not available, with a moderate risk assessment rating of 3. While the structure's condition is not rated, it is subject to regular state inspections and enforcement measures to ensure its reliability and safety. The dam's emergency action plan status, risk management measures, and inundation maps readiness are currently undisclosed.
Owned by the local government and designed by Morrison Knudsen, Tmpa Gibbons Creek Mine Dam 5a is a critical infrastructure supporting various purposes beyond flood control, reflecting its significance in water resource management. With its strategic location, sizeable storage capacity, and regulated operation, this dam serves as a key asset in safeguarding the water supply and mitigating potential hazards in the region. Enthusiasts of water resources and climate resilience would find this structure a compelling case study in sustainable dam management practices.

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 Tmpa Gibbons Creek Mine Dam 5a
Where does the data for Tmpa Gibbons Creek Mine Dam 5a 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.
