Lac Shayne Dam dam
Lac Shayne Dam
Located in Washington, Missouri, the Lac Shayne Dam is a local government-owned structure that serves multiple purposes, with its primary focus being on recreation. Built in 1979, this earth dam stands at a height of 72 feet, with a length of 1600 feet, creating a reservoir with a storage capacity of 2475 acre-feet. The dam poses a high hazard potential but is currently in satisfactory condition, as per the latest assessment in March 2021.
Situated on Pond Creek, a tributary in the area, the Lac Shayne Dam is regulated and inspected by the Dam and Reservoir Safety Program of Missouri. The dam's spillway type is uncontrolled, with a maximum discharge capacity of 290 cubic feet per second. Despite its high hazard potential, the risk assessment for Lac Shayne Dam is moderate, with measures in place for risk management. The dam is a vital part of the community, offering not only recreational opportunities but also serving as a key infrastructure for water resource management in the region.
For water resource and climate enthusiasts, the Lac Shayne Dam presents an intriguing case study in dam safety and management. With its location in a high-risk area and the potential for significant impact in case of failure, the dam serves as a reminder of the importance of regular inspections, risk assessments, and emergency preparedness. As climate change continues to pose challenges to water infrastructure, understanding the role of dams like Lac Shayne in mitigating risks and ensuring water security becomes increasingly crucial.

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 Lac Shayne Dam
Where does the data for Lac Shayne 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 High 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.
