Lake Tishomingo Dam dam
Lake Tishomingo Dam
Lake Tishomingo Dam, located in Cedar Hill, Missouri, stands as a vital recreational site for water resource and climate enthusiasts. Constructed in 1950, this rockfill dam is designed to provide not only leisure activities but also essential water storage capabilities. With a height of 68 feet and a storage capacity of 3,128 acre-feet, the dam ensures a reliable water source for the surrounding area.
Managed by private owners but regulated by the state of Missouri, Lake Tishomingo Dam undergoes regular inspections to maintain its satisfactory condition and high hazard potential. The dam's spillway, outlet gates, and valve system are designed to manage potential risks and ensure the safety of the surrounding community. Despite its moderate risk assessment, the dam serves as a critical infrastructure for water management and recreation in the region, highlighting the importance of sustainable water resource practices in the face of changing climate conditions.
Surrounded by the scenic beauty of Jefferson County and Belew Creek, Lake Tishomingo Dam not only provides a picturesque backdrop for outdoor enthusiasts but also serves as a reminder of the delicate balance between water resource management and climate resilience. With its rich history and strategic location, the dam continues to play a crucial role in meeting the recreational needs of the community while safeguarding against potential hazards, making it an essential site for water and climate enthusiasts alike.

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
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Lake Tishomingo Dam
Where does the data for Lake Tishomingo 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.
