Lake Bono Del Dam dam
Lake Bono Del Dam
Lake Bono Del Dam in Missouri stands as a marvel of engineering, completed in 1954 for the primary purpose of recreation. This private earth dam, with a height of 27 feet, holds a maximum storage capacity of 58 acre-feet and a normal storage of 35 acre-feet. Situated on the TR to Belew Creek, the dam boasts a surface area of 4 acres and serves a drainage area of 60 square miles. Despite its high hazard potential, the dam's condition assessment remains unrated, with its last inspection dating back to November 1980.
Surrounded by the picturesque landscape of Jefferson County, Missouri, Lake Bono Del Dam offers an oasis for water resource and climate enthusiasts seeking adventure and tranquility. With its buttress core design and unlisted foundations, the dam exudes a sense of resilience and strength amidst its natural surroundings. Although not regulated by the state, this dam continues to provide a haven for outdoor activities such as fishing, boating, and wildlife observation. Its location near Cedar Hill adds to its charm, making it a hidden gem for those looking to escape the hustle and bustle of city life.
As a relic of the past with its construction dating back over half a century ago, Lake Bono Del Dam remains a testament to human ingenuity and the enduring connection between water resources and climate. While its emergency action plan and risk assessment are yet to be fully realized, the dam's historical significance and recreational value cannot be understated. As visitors explore its shores and waters, they are reminded of the delicate balance between nature and human intervention, making Lake Bono Del Dam a beacon of sustainability and stewardship in the heart of Missouri.

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 Lake Bono Del Dam
Where does the data for Lake Bono Del 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.
