Grindstone-Lost-Muddy Watershed Dam D-23 dam
Grindstone-Lost-Muddy Watershed Dam D-23
Grindstone-Lost-Muddy Watershed Dam D-23, located in DeKalb, Missouri, is a key structure managed by the local government for grade stabilization along the TR-N.FORK LOST CREEK. Built in 1975 by the USDA NRCS, this earth dam stands at 30 feet tall and stretches 600 feet in length. With a storage capacity of 223 acre-feet and a drainage area of 350 square miles, the dam plays a crucial role in managing water resources in the region.
Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level. The spillway, with a width of 50 feet, is uncontrolled, allowing for controlled release of water during high flow events. The dam has not been rated for its condition assessment, indicating the need for further evaluation to ensure its long-term functionality. The primary purpose of the dam is grade stabilization, with a focus on protecting surrounding areas from erosion and sediment buildup.
In the event of an emergency, it is crucial for the local government to have an Emergency Action Plan (EAP) in place. While details about the EAP for Grindstone-Lost-Muddy Watershed Dam D-23 are not available, it is essential for stakeholders to ensure that proper measures are in place to mitigate any potential risks. With its strategic location and role in managing water resources, this dam serves as a vital infrastructure for the community and underscores the importance of sustainable water resource management in the face of changing climate conditions.
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 Grindstone-Lost-Muddy Watershed Dam D-23
Where does the data for Grindstone-Lost-Muddy Watershed Dam D-23 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.
