Johnsons Draw Ws Scs Site 4 Dam dam
Johnsons Draw Ws Scs Site 4 Dam
Johnsons Draw WS SCS Site 4 Dam, located in Crockett, Texas, serves as a critical infrastructure designed by the USDA NRCS to mitigate flood risks along Garrett Draw. Completed in 1959, this earth dam stands at a height of 45 feet with a hydraulic height of 54 feet, providing a storage capacity of 8,091 acre-feet and a drainage area of 17.76 square miles. The dam's primary purpose is flood risk reduction, with a spillway width of 504 feet and a maximum discharge of 30,217 cubic feet per second.
The dam's structural integrity has been assessed as satisfactory, with the last inspection carried out in May 2016. It is regulated by the Texas Commission on Environmental Quality (TCEQ) and has state permitting, inspection, and enforcement mechanisms in place. Despite the moderate risk assessment level, the dam has not been rated for hazard potential, indicating a relatively stable condition. With a history of successful flood risk reduction and a well-maintained operational status, Johnsons Draw WS SCS Site 4 Dam remains a crucial component of water resource management in the region.
As an essential part of the flood control infrastructure in the area, Johnsons Draw WS SCS Site 4 Dam plays a vital role in protecting the community of Ozona and the surrounding areas from potential flood events. With its strategic design, reliable operation, and satisfactory condition, this dam stands as a testament to the importance of effective water resource management and climate resilience in safeguarding communities against natural disasters.
Dam data reference
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 Johnsons Draw Ws Scs Site 4 Dam
Where does the data for Johnsons Draw Ws Scs Site 4 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.
