Shahan Dam dam
Shahan Dam
Shahan Dam, located in Louisiana, Missouri, was completed in 1993 for the primary purpose of grade stabilization. This private-owned earth dam sits on TR-Bear Creek and has a height of 26 feet, with a maximum storage capacity of 47 acre-feet and a drainage area of 155 acres. The dam's spillway type is uncontrolled, with a width of 10 feet, and it has a low hazard potential and a moderate risk assessment rating.
Despite not being regulated or permitted by the state, Shahan Dam serves various purposes such as fire protection, stock, and small fish pond in addition to grade stabilization. The dam, constructed with a stone core and resting on a soil foundation, has a length of 362 feet and a surface area of 2 acres. While the dam's condition is currently not rated, it is listed as having moderate risk with no emergency action plan in place.
Water resource and climate enthusiasts may find Shahan Dam intriguing for its unique design and multi-purpose functionality. With its strategic location and moderate risk assessment, the dam presents an opportunity for further study and assessment in the realm of water resource management and climate change adaptation. Its construction and operational details, coupled with its low hazard potential, make Shahan Dam an interesting case study for those interested in the intersection of dam infrastructure, environmental stewardship, and risk management.

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 Shahan Dam
Where does the data for Shahan 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.
