Grindstome-Lost-Muddy Watershed Dam Lt-125 dam
Grindstome-Lost-Muddy Watershed Dam Lt-125
Located in DeKalb, Missouri, the Grindstome-Lost-Muddy Watershed Dam Lt-125, also known as the John Donovan Dam Lt-125, was completed in 1985 by the USDA NRCS. This private dam, with a primary purpose of grade stabilization, stands at a height of 30 feet and spans a length of 450 feet along the TR-GRINDSTONE CREEK. With a storage capacity of 46 acre-feet and a drainage area of 325 square miles, the dam plays a crucial role in managing water resources in the region.
The dam's spillway, with a width of 14 feet, is uncontrolled and has a low hazard potential. While the condition assessment is not rated, the risk assessment deems the dam to have a moderate risk level. Despite not being regulated by the state or federal agencies, the dam serves as a valuable infrastructure for flood control and water management within the watershed. With its earth and stone core construction, the Grindstome-Lost-Muddy Watershed Dam Lt-125 is a key component in safeguarding the surrounding environment and communities from potential water-related hazards.
As a significant structure in the Rock Island District, the Grindstome-Lost-Muddy Watershed Dam Lt-125 stands as a testament to the collaborative efforts of the Natural Resources Conservation Service and private owners in promoting sustainable water resource management. With its strategic location and essential role in grade stabilization, this dam serves as a vital asset in mitigating the impacts of climate change and ensuring the resilience of the local ecosystem. Its completion in 1985 marks a milestone in the region's water infrastructure development, highlighting the importance of proactive measures in adapting to changing environmental 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 Grindstome-Lost-Muddy Watershed Dam Lt-125
Where does the data for Grindstome-Lost-Muddy Watershed Dam Lt-125 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.
