Grindstone-Lost-Muddy Watershed Dam A-26 dam
Grindstone-Lost-Muddy Watershed Dam A-26
Grindstone-Lost-Muddy Watershed Dam A-26, located in DeKalb, Missouri, is a vital structure designed by the USDA NRCS for grade stabilization along the TR-GRINDSTONE CREEK. Completed in 1969, this earth dam stands at a height of 25 feet and has a length of 615 feet, providing a storage capacity of 78 acre-feet to help manage the drainage area of 32 square miles. With a spillway width of 30 feet and a maximum discharge of 174 cubic feet per second, this dam plays a crucial role in controlling water flow and preventing erosion in the region.
Owned by the local government, Grindstone-Lost-Muddy Watershed Dam A-26 serves the primary purpose of grade stabilization and is primarily constructed of earth and stone materials on a soil foundation. With a high hazard potential and a moderate risk assessment rating, it is essential to ensure the proper maintenance and inspection of this dam to safeguard against any potential risks or emergencies. Despite not being regulated by the state, the dam's strategic location and design make it a key component in the water resource management of the area.
As part of the Rock Island District, Grindstone-Lost-Muddy Watershed Dam A-26 highlights the collaborative efforts between different agencies and organizations in managing water resources and climate challenges in Missouri. With its unique design and functionality, this dam stands as a testament to the importance of sustainable water infrastructure for the community's resilience and environmental protection.

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 A-26
Where does the data for Grindstone-Lost-Muddy Watershed Dam A-26 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.
