Lake Cooper Dam dam
Lake Cooper Dam
Lake Cooper Dam, located in Archer, Texas, was completed in 1953 and serves as a vital structure for both recreation and water supply purposes. Designed by Ernest L Andrews, this earth dam spans 2,050 feet in length and stands at a height of 49 feet, with a storage capacity of 7,163 acre-feet. The dam overlooks Mesquite Creek and is regulated by the Texas Commission on Environmental Quality (TCEQ), ensuring state jurisdiction, permitting, inspection, and enforcement measures are in place.
Despite its historical significance, Lake Cooper Dam currently has a poor condition assessment and is considered to have a moderate risk level. The last inspection in 1987 highlighted the need for improvements, and with the hazard potential not available, there is an urgency for maintenance and risk management measures to be implemented. The dam features an uncontrolled spillway with a width of 500 feet and four uncontrolled outlet gates, emphasizing the importance of ensuring the safety and integrity of the structure for the surrounding community and environment.
As water resource and climate enthusiasts, the intriguing aspects of Lake Cooper Dam lie in its dual purpose of providing recreational opportunities while also safeguarding water supply needs. With its proximity to Mesquite Creek and the potential risks associated with its current condition, there is a call for attention and action to preserve this essential infrastructure for future generations. The collaboration between local government, regulatory agencies, and stakeholders will be key in ensuring the sustainable management and maintenance of Lake Cooper Dam for years to come.

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 Cooper Dam
Where does the data for Lake Cooper 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.
