Monument dam
Monument
Monument, also known as Kennedy No. 1, is a Federal-owned water resource located in Jones, South Dakota. Constructed in 1938 by the Forest Service, this earth dam stands at 22 feet high with a length of 450 feet, creating a storage capacity of 80 acre-feet. The primary purpose of Monument is for fire protection, stock watering, and as a small fish pond, catering to various wildlife needs in the area.
Despite being classified as low hazard potential, Monument plays a crucial role in providing water for both wildlife and firefighting efforts in the region. The dam is situated on Dry Draw, within the St. Paul District, and is managed by the Forest Service. With a moderate risk rating, regular inspections ensure its structural integrity and functionality, even though its condition assessment is currently not rated. The presence of Monument not only supports local ecosystems but also contributes to the overall water resource management in the area.
Monument's historical significance as a water storage facility highlights the intersection of water resource management and climate resilience. As climate change continues to impact water availability and quality, structures like Monument become increasingly vital for maintaining ecosystem balance and supporting various wildlife populations. With its strategic location and purposeful design, Monument stands as a testament to the importance of sustainable water management practices in the face of evolving climatic challenges.
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 Monument
Where does the data for Monument 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.
