Missile 249 (Nid) dam
Missile 249 (Nid)
Missile 249 (Nid), also known as Church Dam, is a captivating water resource structure located in Quinn, South Dakota. Built in 1936 by the Forest Service, this Earth-type dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 24 feet and a length of 450 feet, Missile 249 has a storage capacity of 60 acre-feet and is situated on the Dry Draw river in Pennington County.
Despite its low hazard potential and moderate risk assessment, Missile 249 has not been rated for its condition as of yet. The dam, which is federally owned and operated, does not fall under state regulation and inspection. However, it is interesting to note that the last inspection was conducted in October 2006 with a recommended frequency of every 10 years. With a maximum discharge of 445 cubic feet per second and an uncontrolled spillway type, this dam continues to play a crucial role in water management and conservation efforts in the region.
Overall, Missile 249 (Nid) is a historic water resource structure that not only serves practical purposes such as fire protection and stock watering but also contributes to the local ecosystem by providing a habitat for fish and wildlife. As an essential part of the Forest Service's operations, this dam stands as a testament to early 20th-century engineering and continues to be a valuable asset in managing water resources in South Dakota. With its unique design and functionality, Missile 249 remains a fascinating site for water resource and climate enthusiasts to explore and appreciate.
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 Missile 249 (Nid)
Where does the data for Missile 249 (Nid) 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.
