Grindstone-Lost-Muddy Watershed Dam C-75 dam
Grindstone-Lost-Muddy Watershed Dam C-75
Located in DeKalb County, Missouri, the Grindstone-Lost-Muddy Watershed Dam C-75 is a key structure designed for grade stabilization by the USDA NRCS. Built in 1973, this earth dam stands at a height of 24 feet and spans 580 feet across TR-LOST CREEK. With a storage capacity of 120 acre-feet and a drainage area of 240 acres, the dam plays a crucial role in managing water resources in the region.
The dam's primary purpose is grade stabilization, serving to control soil erosion and prevent sediment runoff into the surrounding waterways. Despite its low hazard potential, the dam has a moderate risk assessment rating of 3, highlighting the importance of ongoing monitoring and maintenance. With a spillway width of 40 feet and uncontrolled spillway type, the dam is equipped to handle a maximum discharge of 295 cubic feet per second in the event of heavy rainfall or flooding, ensuring the safety of downstream communities.
While the dam's condition is currently not rated, its strategic location in the Grindstone-Lost-Muddy watershed underscores its significance in water resource management efforts. With a focus on sustainability and risk mitigation, the dam serves as a vital infrastructure asset in protecting the local environment and enhancing climate resilience in the region.

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 Grindstone-Lost-Muddy Watershed Dam C-75
Where does the data for Grindstone-Lost-Muddy Watershed Dam C-75 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.
