Magruder Dam dam
Magruder Dam
Magruder Dam, located in Shelby, Missouri, is a privately owned structure on Crooked Creek that serves the primary purpose of grade stabilization. Built in 1995, this earth dam stands at a height of 22 feet and spans a length of 813 feet, with a storage capacity of 73 acre-feet. Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level, indicating the need for ongoing monitoring and risk management measures.
With a spillway width of 10 feet and no outlet gates, Magruder Dam features an uncontrolled spillway type and utilizes stone core materials on a soil foundation. The dam's condition remains unrated, but its risk assessment suggests a moderate level of risk, prompting further evaluation and potential action to mitigate any potential hazards. Although not under federal oversight, the dam plays a crucial role in water resource management within the region, highlighting the importance of maintaining and monitoring dams for both safety and environmental sustainability.
As a key infrastructure for water management in the area, Magruder Dam is an essential component in maintaining the stability of Crooked Creek and surrounding areas. While the dam currently poses a low hazard potential, its moderate risk level underscores the need for ongoing assessment and management to ensure the safety and integrity of the structure. With no recent inspection data available, stakeholders should prioritize regular monitoring and maintenance to address any potential issues and uphold the dam's functionality for the community and the environment.

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 Magruder Dam
Where does the data for Magruder 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 Low 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.
