John Bollinger No. 1 Dam Dam
John Bollinger No. 1 Dam
John Bollinger No. 1 Dam, located in Fredericktown, Missouri, was completed in 1978 and serves primarily for irrigation purposes. This earth dam stands at a height of 18 feet, with a storage capacity of 106 acre-feet. Situated on the TR to Saline Creek, the dam covers a surface area of 11 acres and drains a 60-square mile watershed, highlighting its significant role in managing water resources in the region.
Despite being privately owned and not regulated by the state, John Bollinger No. 1 Dam poses a high hazard potential, underscoring the importance of regular inspections and maintenance. The dam's condition is currently not rated, and its last inspection dates back to August 1980. With its buttress core type and unlisted foundation, the dam's structural integrity and safety measures should be closely monitored to prevent any potential risks or emergencies that may arise from its operations.
Water resource and climate enthusiasts will find John Bollinger No. 1 Dam a fascinating site to study, given its historical background, design features, and vital role in supporting irrigation activities in the area. As a key infrastructure for water management, the dam's characteristics and operational aspects offer valuable insights into the intersection of human intervention and natural resources, making it a compelling subject for further research and analysis in the field of water resource management and climate resilience.

About John Bollinger No. 1 Dam
Where does the data for John Bollinger No. 1 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 below 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.

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.
