Longview No 2 dam
Longview No 2
Longview No 2, located in Jackson County, Missouri, is a recreational earth dam completed in 1947 with a height of 25 feet and a storage capacity of 334 acre-feet. This dam, managed by the Kansas City District of the US Army Corps of Engineers, serves the primary purpose of recreation, providing opportunities for outdoor activities such as fishing, boating, and wildlife observation. Despite its low hazard potential, the dam has not been rated for its condition since its last inspection in 1980.
Situated on the TR Lumpkins Fork Offstream, Longview No 2 offers a serene environment for visitors to enjoy the surrounding natural beauty while engaging in water-based activities. Although the dam is not regulated by the state of Missouri, it still plays a crucial role in water resource management within the region, with a drainage area of 870 square miles. With its historical significance and potential for further recreational development, Longview No 2 continues to be a valuable asset for the local community and climate enthusiasts alike.
While Longview No 2 may not be the largest or most technologically advanced dam in the region, its contribution to water storage, recreation, and environmental conservation cannot be overlooked. As climate change continues to impact water resources, the maintenance and upkeep of structures like Longview No 2 are essential for ensuring the sustainability of our natural ecosystems and the enjoyment of future generations. Whether for leisure or conservation purposes, Longview No 2 stands as a symbol of the intersection between human ingenuity and the forces of nature.

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 Longview No 2
Where does the data for Longview No 2 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.
