About this dam

Tmpa Gibbons Creek Mine Dam Sp-1

Tmpa Gibbons Creek Mine Dam Sp-1, located in Grimes, Texas, is a local government-owned structure designed by Morrison Knudson. This earth dam, standing at a height of 25 feet, was completed in 1987 and serves a primary purpose that is classified as 'Other'. The dam has a storage capacity of 1095 acre-feet, with a normal storage level of 440 acre-feet and a surface area of 87.5 acres.

The dam, situated on Rock Lake Creek, is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes state permitting, inspection, and enforcement. With a spillway type classified as 'Uncontrolled' and two uncontrolled outlet gates, the dam has a moderate risk assessment rating. Despite not having a hazard potential or condition assessment rating available, the structure is considered to have a moderate risk level (3) associated with it.

Overall, Tmpa Gibbons Creek Mine Dam Sp-1 presents an intriguing case study for water resource and climate enthusiasts due to its unique design elements, regulatory oversight, and risk assessment profile. The dam's historical significance, operational details, and environmental impact make it a noteworthy subject for further research and analysis in the field of water resource management and climate resilience.

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.

FAQ

About Tmpa Gibbons Creek Mine Dam Sp-1

Where does the data for Tmpa Gibbons Creek Mine Dam Sp-1 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.
