Green Valley Farm dam
Green Valley Farm
Green Valley Farm in St. Charles, Missouri, is home to a private Earth dam built in 1972 for fire protection, stock, or as a small fish pond. This dam stands at a height of 25 feet and has a storage capacity of 54 acre-feet, with a normal storage level of 29 acre-feet. The dam is located on TR-SEHRT CREEK and serves as a crucial water resource for the farm.
Despite its importance, the dam at Green Valley Farm poses a high hazard potential and has not been rated for its condition since its last inspection in 1981. The lack of recent assessments raises concerns about the dam's safety and the potential risks it poses to the surrounding area. With its primary purpose being fire protection and stock, it is crucial for the owners to prioritize regular inspections and maintenance to ensure the dam's structural integrity and prevent any potential disasters.
Green Valley Farm's Earth dam serves as a vital resource for water storage and fire protection in the area. As enthusiasts of water resources and climate, it is essential to monitor and address any potential risks associated with the dam to safeguard the farm and its surrounding environment. By staying informed and taking proactive measures, the owners can ensure the sustainability and safety of this important water infrastructure for future generations.

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 Green Valley Farm
Where does the data for Green Valley Farm 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.
