Pinson Gravel Company Dam dam
Pinson Gravel Company Dam
Pinson Gravel Company Dam, located in Cruise Mill, Missouri, is a privately owned structure that serves the primary purpose of storing tailings. Completed in 1973, this dam stands at a height of 79 feet and has a length of 3234 feet. With a storage capacity of 875 acre-feet and a drainage area of 631 square miles, the dam plays a crucial role in managing water resources in the area.
The dam, which is regulated by the DAM AND RESERVOIR SAFETY PROG in Missouri, has a high hazard potential but is currently assessed to be in satisfactory condition. It features an uncontrolled spillway with a width of 90 feet and has no outlet gates. The latest inspection in March 2018 deemed the structure to be in good standing, with a moderate risk assessment rating of 3. While no emergency action plan or inundation maps have been prepared, the dam is subject to regular state inspections and enforcement measures to ensure public safety and environmental protection.
Overall, Pinson Gravel Company Dam plays a vital role in water management and conservation efforts in Washington County, Missouri. With its solid design and satisfactory condition, the dam continues to serve its intended purpose effectively while being subject to rigorous state regulations and inspections. This structure stands as a testament to the importance of responsible dam operation and maintenance in safeguarding water resources and mitigating risks associated with potential emergencies.

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 Pinson Gravel Company Dam
Where does the data for Pinson Gravel Company 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 High 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.
