Summary
This local government-owned earth dam stands at a height of 27 feet and serves primarily for grade stabilization along the TR-West Fork Lost Creek. With a storage capacity of 26 acre-feet and a drainage area of 301 acres, this dam plays a vital role in managing water resources in the region.
Despite being classified as having a low hazard potential, the Grindstone-Lost-Muddy Watershed Dam Lt-107 is rated as not assessed for its condition. The spillway is uncontrolled with a width of 14 feet, and there are no outlet gates associated with the structure. The risk assessment for this dam is considered moderate, with a DSAC assigned date and risk management measures pending evaluation. As climate change continues to impact water resources, the importance of maintaining and assessing infrastructure like Grindstone-Lost-Muddy Watershed Dam Lt-107 becomes increasingly critical for ensuring the safety and resilience of communities in the area.
In the face of changing weather patterns and increasing water demands, the Grindstone-Lost-Muddy Watershed Dam Lt-107 stands as a key structure for grade stabilization and water management in DeKalb, Missouri. As stakeholders work towards evaluating and improving the condition and risk management of this dam, it serves as a reminder of the interconnectedness between water resources, climate change, and infrastructure resilience. The collaboration between local government and federal agencies like the USDA NRCS underscores the importance of proactive measures in safeguarding water resources for future generations in the region.

Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
