Renns Lake Dam dam
Renns Lake Dam
Renns Lake Dam, located in Jefferson City, Missouri, was completed in 1950 for the primary purpose of recreation. This private dam, with a height of 30 feet and a storage capacity of 112 acre-feet, is situated on the TR-Moreau River within the St. Louis District. Despite being privately owned and not state-regulated, the dam poses a high hazard potential due to its condition being labeled as "Not Rated."
With a surface area of 7 acres and a drainage area of 450 square miles, Renns Lake Dam provides a picturesque setting for outdoor enthusiasts to enjoy water-based activities. Although there have been no recent inspections or assessments of its condition, the dam continues to serve its recreational purpose for the local community. As climate change impacts water resources and infrastructure, the need for regular maintenance and monitoring of dams like Renns Lake becomes crucial to ensure public safety and environmental sustainability.
As climate and water resource enthusiasts, the data on Renns Lake Dam highlights the importance of balancing recreational benefits with the potential risks associated with aging infrastructure. With its high hazard potential and unknown condition assessment, the dam serves as a reminder of the ongoing need for proactive management and maintenance of water-related structures in the face of changing environmental conditions. By staying informed and advocating for responsible stewardship of water resources, enthusiasts can contribute to safeguarding the integrity and safety of dams like Renns Lake for future generations to enjoy.

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 Renns Lake Dam
Where does the data for Renns 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.
