Koepke Lake Dam North dam
Koepke Lake Dam North
Located in Innsbrook, Missouri, the Koepke Lake Dam North is a private earth dam that serves multiple purposes including fire protection, stock maintenance, and small fish pond creation. Built in 1967, this dam stands at a height of 39 feet with a structural height of 40 feet and a length of 600 feet. It holds a maximum storage capacity of 152 acre-feet and covers a surface area of 10 acres, making it an essential water resource for the surrounding area.
Managed by the DAM AND RESERVOIR SAFETY PROG, the Koepke Lake Dam North is regulated, permitted, inspected, and enforced by the state of Missouri to ensure its safety and integrity. With a high hazard potential and a satisfactory condition assessment, this dam poses a moderate risk level (3) and follows an inspection frequency of 3 years. Although no emergency action plan (EAP) has been prepared, the dam meets safety guidelines and is equipped with an uncontrolled spillway system to manage overflow.
Enthusiasts of water resources and climate will find the Koepke Lake Dam North an intriguing structure, not only for its functional purposes but also for its role in maintaining the ecosystem of TR CHARRETTE CREEK. With a focus on safety and risk management, this dam serves as a vital component in the region's water infrastructure, highlighting the importance of maintaining and monitoring such structures in the face of changing climate conditions.

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 Koepke Lake Dam North
Where does the data for Koepke Lake Dam North 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.
