Spangler Lake Dam dam
Spangler Lake Dam
Spangler Lake Dam, located in Harrisonville, Missouri, is a private earth dam built in 1989 with a height of 20 feet and a storage capacity of 160 acre-feet. The dam is situated on Tributary Big Creek and serves as a vital resource for water storage and flood control in the region. With a low hazard potential and a condition assessment of "Not Rated," the dam plays a crucial role in maintaining water resources for the surrounding area.
Owned and managed privately, Spangler Lake Dam does not fall under state regulation or inspection. Despite its unlisted foundation and buttress core type, the dam stands as a sturdy structure with a normal storage capacity of 100 acre-feet and a surface area of 15 acres. The dam's location in Cass County, Missouri, contributes to the overall drainage area of 450 acres, making it an essential feature for water resource and climate enthusiasts to monitor and study.
With its completion in 1989, Spangler Lake Dam has become a key component in the water management infrastructure of the area. While its emergency action plan status and risk assessment remain unknown, the dam's role in controlling water flow and providing storage capabilities is undeniable. As water resource and climate enthusiasts continue to explore and analyze the impact of such structures, Spangler Lake Dam stands as a testament to the importance of sustainable water management practices in the face of changing climate patterns.

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 Spangler Lake Dam
Where does the data for Spangler Lake Dam 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.
