Ripple Lake Dam dam
Ripple Lake Dam
Ripple Lake Dam, located in Clarksville, Missouri, is a private-owned structure primarily used for fish and wildlife pond purposes. Completed in 1975, this earth-type dam stands at a height of 25 feet and has a maximum storage capacity of 49 acre-feet. With a surface area of 2 acres and a drainage area of 38.4 square miles, the dam serves as a significant water resource in the region.
The dam's spillway type is uncontrolled with a width of 14 feet, and it has a maximum discharge capacity of 116 cubic feet per second. While the dam is rated as not assessed for condition, it has been categorized as having a significant hazard potential. The risk assessment for Ripple Lake Dam is considered moderate, and it is not under the jurisdiction of state regulation or inspection. Despite its moderate risk, the dam remains a vital structure for water conservation and wildlife preservation in the area.
Overall, Ripple Lake Dam plays a crucial role in maintaining the ecosystem and water supply in Pike County, Missouri. As a key feature in the TR-Calumet Creek watershed, the dam provides essential benefits for fire protection, stock, small fish ponds, grade stabilization, and recreation. While it may pose some risks, the dam's importance for fish and wildlife habitats and water conservation cannot be understated, making it a valuable asset for water resource and climate enthusiasts to appreciate and monitor.

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 Ripple Lake Dam
Where does the data for Ripple 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 Significant 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.
