Summary
With a height of 40 feet and a length of 1867 feet, this earth dam on the Gurley Draw river serves to protect the surrounding area from potential flooding events. The dam has a normal storage capacity of 179 acre-feet and a maximum discharge of 22,572 cubic feet per second.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Johnsons Draw WS SCS Site 7 Dam is regularly inspected and maintained to ensure its structural integrity. The dam features an uncontrolled spillway with a width of 253 feet and is equipped with five outlet gates for effective water flow management. Despite being assessed as in fair condition in 2016, the dam poses a moderate risk level and has not had an Emergency Action Plan update since 2011.
For water resource and climate enthusiasts, the Johnsons Draw WS SCS Site 7 Dam offers a fascinating example of engineering ingenuity in flood risk reduction. Its strategic location and design highlight the importance of proactive measures in safeguarding communities against the impact of natural disasters. As efforts continue to monitor and maintain the dam's condition, its role in water resource management in the region remains a critical aspect of sustainable development and climate resilience.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
