Branneky Lake Dam dam
Branneky Lake Dam
Branneky Lake Dam, located in Bridgeton, Missouri, is a private-owned structure that was completed in 1966 for recreational purposes. This Earth-type dam stands at a height of 34 feet and has a storage capacity of 109 acre-feet, with a normal storage level of 7 acre-feet. Situated along TR to Missouri River, the dam serves a drainage area of 90 square miles and covers a surface area of 6 acres. With a high hazard potential, the dam has not been inspected since 1981 and is currently rated as "Not Rated" in terms of condition assessment.
Despite its age, Branneky Lake Dam continues to provide recreational opportunities for visitors in the St. Louis County area. However, with the last inspection dating back to 1981, concerns about the dam's safety and maintenance have arisen, especially given its high hazard potential. The lack of recent assessments and updates on emergency action plans raise questions about the dam's readiness to handle potential risks and emergencies. Climate and water resource enthusiasts may find interest in advocating for improved monitoring and maintenance of the dam to ensure the safety of both the structure and the surrounding community.
With the Kansas City District as its overseeing authority, Branneky Lake Dam's current status as "Not Rated" in terms of condition assessment and lack of recent inspections raise concerns about its structural integrity and safety measures. As a vital structure for recreational purposes in the area, it is crucial for relevant agencies to prioritize regular inspections, maintenance, and emergency preparedness to mitigate potential risks and ensure the safety of the dam and the community it serves. Advocacy for increased oversight and updates on emergency action plans can help address these concerns and promote the sustainable management of water resources in the region.

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 Branneky Lake Dam
Where does the data for Branneky 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.
