Henning Lake Dam dam
Henning Lake Dam
Henning Lake Dam, located in Purdin, Missouri, was completed in 1951 and serves as a private recreational facility with a primary purpose of providing leisure activities for water resource and climate enthusiasts. The dam is of Earth type with a height of 30 feet, offering a storage capacity of 64 acre-feet and covering a surface area of 4 acres. While the dam has a low hazard potential, its condition assessment is currently not rated, indicating a need for further evaluation.
Situated along the TR-West Locust Creek, Henning Lake Dam falls under the jurisdiction of the state of Missouri and is not regulated or permitted by any state agency. The dam's design features a buttress core type and an unlisted/unknown foundation. Despite a lack of official inspections and enforcement, the dam's emergency action plan status, risk assessment, and inundation maps preparedness are not currently available. However, the dam's location in a tranquil setting with a scenic backdrop makes it an ideal destination for outdoor recreation enthusiasts seeking a peaceful getaway.
With its serene surroundings and recreational opportunities, Henning Lake Dam offers a charming escape for those interested in water resources and climate-related activities. While the dam's infrastructure and regulatory oversight may require further attention, its low hazard potential and beautiful setting make it an inviting destination for individuals looking to enjoy nature and engage in outdoor pursuits. Whether for fishing, boating, or simply relaxing by the water, Henning Lake Dam provides a picturesque retreat for enthusiasts seeking a peaceful and rejuvenating experience in Linn County, 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 Henning Lake Dam
Where does the data for Henning 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 Low 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.
