Johnsons Draw Ws Scs Site 7 Dam dam
Johnsons Draw Ws Scs Site 7 Dam
Located in Crockett County, Texas, the Johnsons Draw WS SCS Site 7 Dam is a crucial flood risk reduction structure designed by the USDA NRCS in 1959. 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
- 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 7 Dam
Where does the data for Johnsons Draw Ws Scs Site 7 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.
