Perry County Comm. Lake Dam dam
Perry County Comm. Lake Dam
Perry County Comm. Lake Dam, located in Saint Marys, Missouri, is a state-regulated earth dam completed in 1971 for recreational purposes. With a structural height of 47 feet and a length of 900 feet, this dam holds a maximum storage capacity of 1690 acre-feet and covers a surface area of 87 acres. The dam is designed by USDA NRCS and is inspected by the DAM AND RESERVOIR SAFETY PROG, ensuring its safety and regulatory compliance.
This high hazard potential dam on the TR-SOUTH FORK SALINE CR river has a spillway width of 240 feet and an uncontrolled spillway type. With a satisfactory condition assessment and a moderate risk rating, the dam has emergency action plans in place and meets regulatory guidelines. The last inspection in December 2017 showed the dam to be in good condition, providing residents and visitors with a safe and enjoyable recreational resource in Perry County.
In case of emergencies, the dam is equipped with valve outlet gates, and the local congressman representing the area is Jason Smith (R). With its solid construction, satisfactory condition, and regulatory compliance, Perry County Comm. Lake Dam stands as a vital water resource for the community while also serving as a recreational haven for outdoor enthusiasts and climate advocates alike.
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.
Plan around the weather

About Perry County Comm. Lake Dam
Where does the data for Perry County Comm. 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 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.
