About this dam

Grindstone-Lost-Muddy Watershed Dam C- 39a

Grindstone-Lost-Muddy Watershed Dam C-39a, located in DeKalb, Missouri, was completed in 1975 with a primary purpose of grade stabilization. This earth dam, standing at a height of 22 feet and stretching 600 feet in length, serves to manage the flow of TR-LOST CREEK and has a storage capacity of 180 acre-feet. Despite being uncontrolled, the spillway of this dam is 40 feet wide, allowing for a maximum discharge of 300 cubic feet per second.

Owned by the local government and designed by USDA NRCS, this dam plays a crucial role in managing water resources in the region. With a low hazard potential and a moderate risk assessment rating, Grindstone-Lost-Muddy Watershed Dam C-39a is vital for mitigating the impact of potential floods and ensuring the stability of the surrounding environment. While it is not currently rated for condition, the dam continues to serve its purpose effectively, enhancing the resilience of the watershed against climatic challenges.

Overall, Grindstone-Lost-Muddy Watershed Dam C-39a stands as a testament to effective water resource management in DeKalb, Missouri. With its sturdy earth structure, ample storage capacity, and strategic location, this dam plays a crucial role in maintaining the ecological balance of the region. As climate change continues to pose challenges to water resources, the presence of well-designed structures like Grindstone-Lost-Muddy Watershed Dam C-39a is essential for ensuring the sustainability and resilience of communities in the face of evolving environmental conditions.

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.

FAQ

About Grindstone-Lost-Muddy Watershed Dam C- 39a

Where does the data for Grindstone-Lost-Muddy Watershed Dam C- 39a 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.
