Springer-Sharon Site Ca-33-H-55-1 dam
Springer-Sharon Site Ca-33-H-55-1
The Springer-Sharon Site Ca-33-H-55-1, also known as the Norman Gibson Structure, is a local government-owned dam located in Chillicothe, Missouri. Built in 1977, this Earth dam serves the primary purpose of grade stabilization along the Thompson River. With a height of 30 feet and a length of 320 feet, the dam has a storage capacity of 30 acre-feet and covers a surface area of 21 acres.
Despite being categorized as a low hazard potential structure, the dam has a moderate risk assessment rating. It features an uncontrolled spillway with a width of 10 feet and has a maximum discharge capacity of 79 cubic feet per second. The condition assessment of the dam is currently marked as "Not Rated," with no recent inspection date available. The structure has not been modified over the years and does not have any outlet gates or associated structures.
Given the important role of dams in managing water resources and mitigating the impacts of climate change, the Springer-Sharon Site Ca-33-H-55-1 stands as a key infrastructure contributing to the protection of the surrounding area from potential flooding and erosion. As water resource and climate enthusiasts continue to monitor and assess the condition of such structures, the Springer-Sharon Site serves as a valuable asset in maintaining the stability and resilience of the Thompson River watershed in Missouri.
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 Springer-Sharon Site Ca-33-H-55-1
Where does the data for Springer-Sharon Site Ca-33-H-55-1 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.
